This paper proposes color affine subspace pursuit (CASSP) for color artifact removal. Local patches in natural color images tend to exhibit a line distribution, so-called a color line. According to this characteristic, a convex-optimization-based image recovery with a local color nuclear norm (LCNN)…
We propose an image colorization method using fast soft-thresholding of singular values (singular value thresholding). An image colorization method with nuclear norm minimization (NNM) has been proposed and brings good results. NNM usually requires iterative application of singular value decompositi…
We propose a new regularization function, named as Arranged Structure tensor Total Variation (ASTV), for multichannel image restoration. Since the standard structure tensor is a matrix whose eigenvalues well encodes local neighborhood information of an image, there has been proposed vectorial total…
