Figure 1From: Image inpainting based on sparse representations with a perceptual metric Brief overview of the sparse representation. (a) Sparse linear combination D x approximating y, where ||x||0 = 6 and (b) two matrices D and X calculated in K-SVD algorithm[36] from Y, where D is a dictionary matrix, X is a matrix including representation coefficient vectors, and Y is a matrix including target signals.Back to article page
