Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0040] The present invention provides a kind of cooperative sparse representation self-adaptive fast face recognition method, it is characterized in that comprising the following steps:
[0041] Step S1: Design a local sparse representation classifier system that does not violate the basic assumptions of the sparse representation definition, denoted as the first system. In order to further improve the calculation rate of the system, this system uses l 2 Norm cooperativity to solve for coefficients, such as figure 1 shown, including the following steps:
[0042] Step S11: read in images of training samples and test samples;
[0043] Step S12: Initialize the training samples and test samples, use bilinear interpolation to scale the training samples and test samples into fixed-size images and integrate them into column vectors, and perform normalization ...
