Image video Big Data: How to gold in the sand

In the fields of intelligent monitoring, attendance security, robot, remote sensing surveying, network information filtering, public security criminal investigation and so on, the big data of image and video are very promising.

The era of massive images and video has come.

Today, Facebook has more than 800 million users. Internet users upload more than 300 million pictures a day, more than 3 million videos. AV video has become a way of entertainment for many people, bringing many opportunities for industry development.

On the other hand, many people use the internet to spread violent, obscene images and videos, and even terrorists use video for teaching. The two sides of large data of image video are becoming more and more prominent.

How to find the gold of industry development in massive image video large data? What is the development opportunity and obstacle of the large data industry in China? A few days ago, "China Science Daily" reporter interviewed a number of experts on this.

Involved in many industries

Lei, a researcher at the first research Institute of the Ministry of Public Security, gave a reporter an example description of the importance of image video large data: In the Yunnan railway station in the detection of the incident, police officers will be the Yunnan railway station in the photo input system of the terror, and the former Xinjiang, the suspect Image Library of the incident, and then found a suspect. Investigators follow this clue and make a breakthrough.

Video surveillance technology has played an important role in public security monitoring, and it has become a sharp weapon to combat illegal crime, but also brought new difficulties to the public security department, such as mass video retrieval, comprehensive ability to judge, lack of identification of fuzzy video image processing. "Lei said.

In the field of Earth observation, large data of image video is also a hotspot. According to Wang Lizhe, a researcher at the Institute of Remote Sensing and digital Earth, the Chinese Academy of Sciences, the new digital Earth Business platform provides a large number of observational data sets. Therefore, it is not only possible to analyze the digital Earth, to obtain multi-scale and large data, but also to analyze the complex socioeconomic data.

"In intelligent monitoring, attendance security, robotics, remote sensing mapping, network information filtering, public security criminal investigation and other fields, image video large data are promising." CAS Academician Tan Tienuo said.

Has entered a large-scale application

In tan-Niu's view, now, image video large data analysis and understanding by leaps and bounds, research and application, and gradually into large-scale industrial application phase.

Relevant data show that the current image video large data industry development, has been the attention of Governments, and through policies to lead.

February 2012, the EU in the new research and Innovation Framework Program horizon2020 and grdi2020, the "large data-oriented data information infrastructure" as a priority area of funding. March 2012, the United States government announced the investment of 200 million dollars to launch the "Big Data Research and development plan", the big data research into the national will. July 2012, Japan launched the "New ICT Strategic Research Plan", focusing on the large data applications required by the network of social media technology.

Tan Tienuo that at present, visual content generation and related industries (video surveillance, machine vision, online video, biometric identification, etc.) to show rapid growth, China's image video data technology and industry are facing important development opportunities.

However, how to realize the Shari of large image data and promote the development of related industries is still facing many problems. Lei for example, in the field of security, video active warning is a research hotspot, because the video can only be used for hindsight, but faced with a database problem.

Tan Tienuo that for the technology and industry of Chinese image video large data, there are some problems, such as relatively few independent innovation, low price competition of homogeneous quality and low degree of internationalization, and weak position in international standard setting.

In addition, the current lack of authoritative evaluation and certification platform, resulting in mixed products and market disorderly competition, foreign products into the country's important areas of security risks. "said Tan-niu.

Standard and algorithmic issues need to be addressed

To exploit the value of large data in image video, experts believe that standard issues and algorithmic innovation are critical.

A few days ago, the first domestic image video large data industry technology innovation Strategic Alliance was formally established. Tan Ox Hope, can use this to establish the test, evaluation, authentication image video data processing technology and product performance and safety performance of technical standards, the establishment of scientific standards, operability of a strong performance evaluation system.

Archie, chief scientist of the Arts, Wang Tao introduced, the current state of video audit is very strict, for the yellow and the problem of terror video, need a suitable algorithm to solve the identification problem. At the same time, the current h.265 and other video standards of patented technology has been in the hands of foreign companies, China is very urgent to establish its own video standards to have the Chinese video industry's own intellectual property rights.

Lei said, image video analysis must be combined with the business to the landing, good algorithms need business to apply, and good business can weaken the problem of the algorithm. In addition, application teams need to be more specialized. ”
