[Research Focus]

1. Intelligent vision: We explore the mechanism and model of compressed sensing and machine learning, and use it for visual perception, stereo reconstruction, image (video) retrieval and mining, intelligent machine detection, intelligent UAV, intelligent medical, VR / AR, and develop intelligent billion pixel dynamic light field imaging for scientific observation and urban monitoring.

2. Intelligent imaging: by combining intelligent technology with optical imaging technology, the research on multi-dimensional, multi-scale and high-resolution intelligent computing imaging technology can provide observation tools and massive basic data for discovering new phenomena of brain perception and operation, revealing neural network computer system, exploring brain disease pathology and mechanism, establishing a bridge between brain science and artificial intelligence, and providing theoretical basis for the development of artificial intelligence New ideas.
