In this paper, a convolutional neural network (CNN) detection analysis is performed for live face detection by binocular cameras, and a binocular stereo matching network with fused edge detection is designed and implemented to target the quality of image details and parallax prediction at edges. Experiments show that the random sample pair confusion loss function can effectively improve the accuracy and generalization of the face live detection algorithm; the multi-task training approach can improve the performance of both faces live detection and face recognition; the algorithm shows excellent performance in both faces live detection and face recognition, especially the generalization of face live detection is greatly improved. A pre-trained convolutional neural network is used to extract features, and a content loss function and a domain loss function are designed to measure the feature distance between two images, and a feedforward neural network is trained as an image transformation network to migrate samples to the same domain. Experiments show that the algorithm can reduce the feature differences between the face live detection data of the two domains and can be used to improve the generalization of the face live detection algorithm.
The systematical report presents our studies on the gecko that integrated biological fundaments for biomimetics -morphology, locomotive mechanics, neural signal decoding and adhesive mechanism that developed a gecko-inspired robot and gecko-robot. A 3 dimensional locomotion gait for a gecko moving on the floor, wall and ceiling was obtained by using one high speed camera recording and image processing. The effect of electric potential on the adhesion was studied. The gecko's foot-toe, a 22 degree-of-freedom motion system, was modulated by stimulating the three neurons on the limb. A stereotaxis method was proposed and the instrument was developed. The brain atlas for the gecko was primarily set up. Based on biological understanding, a bio-inspired geckolike robot was developed and the characteristics of the mechanics were investigated. The robot's gait and motion coordination was introduced from the three dimensional gait results. Locomotion of the gecko was modulated by implanting electrodes into the gecko's middle brain and stimulating by a wireless controlling system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
