Embodiment Construction
[0041] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0042] figure 1 It is a system frame diagram of a high-resolution face image synthesis method based on a deep sparse representation algorithm of the present invention. It mainly includes dictionary learning algorithm, deep sparse representation algorithm, training and testing.
[0043] Dictionary learning algorithm, let X=[x 1 |x 2 |...|x n ] is the input training data of n samples; the dictionary learning algorithm uses the data (X) to learn the dictionary (D) and sparse representation (A); the objective function of dictionary learning is:
[0044]
[0045] Among them, A=[α 1 |α 2 |...|α n ] is sparse coding, ‖·‖ 1 on behalf of l 1 Norm, λ is a regularization constant; in ...
