Want computers to see better in the real world? Train them in a virtual reality

Training and testing object detectors with virtual images.


Researchers have built up another approach to enhance how computers “see” and “understand” protests in reality via preparing the computer vision frameworks in a virtual domain.

For computers to learn and precisely perceive objects, for example, a building, a road, or people, the machines must depend on handling tremendous measure of named information, for this situation, pictures of items with exact comments. A self-driving auto, for example, needs a large number of pictures of streets and autos to gain from.

Datasets consequently assume a significant part in the preparation and testing of the computer vision frameworks. Utilizing physically named preparing datasets, a computer vision framework looks at its present circumstance to known circumstances and makes the best move it can “think” or – whatever that happens to be.

Kunfeng Wang, an associate professor at China’s State Key Laboratory for Management and Control for Complex Systems said, “However, collecting and annotating images from the real world is too demanding in terms of labor and money investments. We actually wanted to tackle the problem that real-world image datasets are not sufficient for training and testing computers vision systems.”

To solve this issue, Wang and his colleagues created a dataset called ParallelEye. ParallelEye was virtually generated by using commercially available computer software, primarily the video game engine Unity3D.

Utilizing a guide of Zhongguancun, one of the busiest urban regions in Beijing, China, as their reference, they reproduced the urban setting essentially by including different structures, autos, and even extraordinary climate conditions. At that point, they set a virtual “camera” on a virtual auto. The auto drove around the virtual Zhongguancun and made datasets that are illustrative of this present reality.

Through their “total control” of the virtual condition, Wang’s group could make greatly particular usable information for their protest distinguishing framework – a reenacted self-sufficient vehicle. The outcomes were great: a checked increment in execution on almost every tried metric. By outlining uniquely designed datasets, a more prominent assortment of independent frameworks will be more useful to prepare.

While their most noteworthy execution increments originated from joining ParallelEye datasets with true datasets, Wang’s group has exhibited that their strategy is prepared to do effortlessly making assorted arrangements of pictures.

Wang said, “Using the ParallelEye vision framework, massive and diversified images can be synthesized flexibly and this can help build more robust computer vision systems.”

Scientists proposed that the approach can be applied to many visual computing scenarios, including visual surveillance, medical image processing, and biometrics. Later, they are planning to an even larger set of virtual images, improve the realism of virtual images, and explore the utility of virtual images for other computer vision tasks.

Wang says: “Our ultimate goal is to build a systematic theory of Parallel Vision, which is able to train, test, understand and optimize computer vision models with virtual images and make the models work well in complex scenes.”

The research team published their findings in IEEE/CAA Journal of Autmatica Sinica, a joint publication of the IEEE and the Chinese Association of Automation.
