The Internet is evolving from the human-centered connection network by which humans create and consume information to the Internet of Things (IoT) network by which information is communicated and processed between things or other distributedcomponents. The Internet of Everything (IoE) technology could be an example of a mix of Big data processing technology and IoT technology through, e.g., a connection with a cloud server.
IoT implementation involves the use of technical elements such as sensors, wired and wireless communications, infrastructure for networks services interface, and security technology. The latest research on technology for connecting things to things has focused on methods for sensor networking, machine-to-machine communication (M2M) or machine-type communications (MTC).
In the IoT environment, intelligent Internet Technology (IT) services may be offered that analyze and collect data produced by the objects connected with one another to provide new value to human life. IoT can have a variety of applications, such as smart home smart building, smart city connected car, smart grid health-care, or smart appliance industry, or state-of-art medical services through the integration or conversion of existing IT technology and different industries.
Moving Picture Experts Group (MPEG), an international standardization organization for multimedia is a standardization organization for multimedia. It has MPEG-2 and MPEG-4, MPEG-7 and MPEG-21. It began with MPEG in 1998. Multimedia application format (MAF)may raise the usability of the standards by responding to the demand from industry by using non-MPEG standards together with traditional MPEG standards. MAF standardization is designed to let the industry benefit of MPEG technology. MAF standardization has two main goals: spread the MPEG standard and make it simple for industries to utilize relevant software.
Meanwhile, data for three dimensional images may be presented as the form of a point cloud. Point cloud is a collection of huge points. Point refers to a point in a three-dimensional space and may be represented in the shape of a vector containing the color and positioncoordinates. The point could be represented by R G, B, and R for instance.
A point cloud that has the 3D image is a large amount of memory. This makes it imperative to employ a point-cloud compression technique. But conventional point cloud compression techniques take time to create and distribute an entirely new codec.Thus it is necessary for an efficient way to utilize a legacy codec (e.g. the two-dimensional video compression technique).
According to the disclosure the invention, a method and device is provided to compress data effectively for point clouds by using a codec that is a an older network.
The objects of the invention described herein are not only limited to those mentioned above and any other non-described objects would be apparent to one who is skilled in the art by the following description.
According to one version of the disclosure, a method of transmitting data to create 3D images involves generating a plurality voxelized point respectively which corresponds to a plurality of voxels from an aplurality points constituting the 3D picture, grouping the plurality voxelized point into a plurality segments, with each segment having at least one of the plurality points, creating a pack of 2D images from the plurality generated 2D images, decoding data and then transmitting the 2D image and sending the encoded data
A different embodiment of the disclosure describes a method of processing data to create the creation of a 3D image. It includes receiving the data, decoding it and packing the 3D data, resulting in a compressed 2D photo, and then getting a number of 2D images by unpacking it. The plurality of 2D images are generated by projecting a plurality voxelized segments and the plurality Voxelized points into a plurality 2D images. In the end it is the 3D reconstruction is done using the 3D image
The following are some of the results of embodiments of the invention
According to the disclosure data for point clouds could be effectively compressed.
According to the report the disclosure, the old 2D compression scheme may still be utilized. This could help to lower costs for development of new technology.
The present invention can have many other effects.Click here to view the patent on USPTO website.

What is a patent?
Granted by the government to protect an invention a patent provides the inventor exclusive rights to create, use to sell, and promote the invention? society gains when a new technology is brought to the market. The benefits can be realized directly as people are able to perform feats previously thought impossible, or indirectly through the economic opportunities that innovation provides (business expansion, job creation).
Patent protection is demanded by many universities and pharmaceutical companies for their research and development. Patents can be granted for a product, process, or method of creating new materials. In order to be granted protection under a patent an invention has to be innovative, novel, and not obvious to other people within the same field.
Patents reward inventors for their commercially profitable inventions. They provide a motivation for inventors to come up with new ideas. Small-scale businesses and inventors are sure that they will earn a return on the investment they make in technology development through patents. They can earn money from their work.
Patents are a crucial part of businesses with the ability to:
Protect the latest products and services;
Enhance the visibility and worth of your products ‘ presence on the market
Make your brand stand out from the competition.

Patents effectively transform the inventor’s information into a tradeable asset which opens new opportunities for employment creation and business growth through licensing or joint ventures.
Small-scale businesses with patent protection are more appealing to investors who are involved in the development and commercialization of technology.
Patenting can generate new ideas and new inventions. These information may be protected by patents.
Patents can be used as an effective deterrent for untrustworthy third parties that profit from an invention’s efforts.
Commercially successful patent-protected technology revenues could be used to finance technological research and development (R&D) and boost the likelihood of improved technology in the near future.
Intellectual ownership of property can be used to convince lenders and investors that there are genuine opportunities to commercialize your product. Sometimes, one powerful patent can open the door to multiple financing opportunities. Patents can be used in conjunction with other IP assets as collateral or security for financing. Investors are also able to view the patents you own to boost the value of their company. Forbes and others have noted that each patent could increase anything from $500,000 to a million dollars in company valuation.

Interested in finding more similar patents? Here are the steps to follow:
1. Create a list of terms to describe your invention based upon the purpose, composition and application.
Write down a concise detailed description of your idea. Do not use generic terms such as “device”, “process,” or “system”. Consider synonyms for the terms you initially chose. Next, take note of crucial technical terms, as well as key words.
Utilize the following questions to help you identify the keywords or concepts.
- What is the objective of the invention? Is it a utilitarian device or an ornamental design?
- Is invention a way to create something or perform an action? Is it a product or procedure?
- What is the composition and function of the invention? What is the physical structure of the invention?
- What is the goal of the invention?
- What are the terms in the technical field and keywords that describe the nature of an invention? A technical dictionary can help you locate the right phrases.
2. These terms will let you look up pertinent Cooperative Patent Classifications at Classification Search Tool. To find the most appropriate classification to your invention, look through the class scheme of the classification (class schedules). You may want to consider substituting the terms you’re using to describe your invention if you don’t find any results in your Classification Text Search with synonyms similar to the words you used in Step 1.
3. Examine the CPC Classification Definition for confirmation of the CPC classification you found. If the classification you have selected has a blue box with an “D” to its left, clicking on the hyperlink will take you to the CPC classification description. CPC classification definitions can aid you in determining the classification’s scope so that you can select the most relevant. The definitions could also contain search tips or other suggestions which could prove useful in further investigation.
4. The Patents Full-Text Database and the Image Database allow you to search for patent documents that have the CPC classification. By focusing on abstracts and drawings that are representative, you can narrow down your search for the relevant patent documents.
5. Utilize this selection of most pertinent patent documents to examine each one thoroughly for similarity to your invention. Take note of the claims and specifications. Contact the applicant as well as the patent examiner for any additional patents.
6. It is possible to find the patent application that has been published and match the CPC classification that you chose in Step 3. You may also employ the same search strategy that you utilized in Step 4 to narrow down your search results to just the most relevant patents by reading the abstracts and representative drawings for each page. Then, you must carefully review the published patent applications, paying particular attention to the claims and the additional drawings.
7. Locate additional US patent publications using keyword searching in PatFT or AppFT databases, classification searching of non-U.S. patents in the below, and searching non-patent literature disclosures of inventions using web search engines. For example:
- Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
- Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
- European Patent Office (EPO) provides esp@cenet to access a network of Europe’s patent databases with access to machine translation of European patents.
- Japan Patent Office (JPO) – with access to machine translations of Japanese patents.
- World Intellectual Property Organization (WIPO) offers PATENTSCOPE with a full-text search of published international patent applications and machine translations for some documents, as well as a list of international patent databases.
- Korean Intellectual Property Rights Information Service (KIPRIS)
- State Intellectual Property Office (SIPO) with machine translation of Chinese patents.
- Other International Intellectual Property Offices with online patent databases include Australia, Canada, Denmark, Finland, France, Germany, Great Britain, India, Israel, Netherlands, Norway, Sweden, Switzerland, and Taiwan.
- Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.
To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
