LIC (Local Intensity Compensation) is an intra-frame motion compensation for video coding, and was a candidate for HEVC. To obtain reference blocks and their coefficients in linear combination, Inoue et al. have applied AHIT (Accelerated Hard Iterative Thresholding) as a solver. However, this algori...
