Embodiment Construction

[0024] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0025] The "terminal" referred to in this context, also known as "smart terminal", refers to an intelligent electronic device that can perform predetermined processing procedures such as numerical calculations and / or logic calculations by running predetermined programs or instructions, which may include a processor and The memory is realized by the processor ex...

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a feature extraction calculation method and equipment for face recognition. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. A series of related technologies that use a video camera or camera to collect images or video streams containing human faces, automatically detect and track human faces in the images, and then perform facial recognition on the detected faces, usually also called portrait recognition and facial recognition. . [0003] Face recognition needs to extract features, and then perform multi-layer neural network operations on the extracted features to obtain calculation results. The existing face recognition feature extraction has a large amount of data, and the large amount of data not only increases the calculation of the processing chip. , and increased energy consumptio...
