Abstract

The invention provides a deep convolutional network for human face identification in a complex scene and a learning method. The network structurally consists of four full convolutional modules and three full connection modules; and parameters of the deep convolutional network are optimized by utilizing a stochastic gradient descent algorithm. The designed deep convolutional network for human face identification is expected to have stable identification performance under multiple view angles for complex illumination in a real application scene; and engineering application demands are met based on relatively high calculation degree under the support of a high-performance GPU.

Description

technical field [0001] The invention relates to a deep convolutional network and a learning method for face recognition in complex scenes, belonging to the field of computer technology. Background technique [0002] The early face recognition algorithms mainly include image preprocessing, proposing traditional face features such as LBP, and applying vector machines to learn and classify the extracted features. Among them, image preprocessing algorithms are particularly critical, including preprocessing algorithms for different lighting conditions, denoising algorithms for image noise, and alignment algorithms for face objects from different angles. After being optimized for a certain face recognition database, such as the classic LFW face recognition database, it has achieved results similar to human recognition levels. [0003] In recent years, with the rapid increase of a wide variety of shooting equipment, a large number of exponentially growing face images appear in var...
