WebNov 10, 2024 · One of the most popular image restoration methods is total variation (TV) model [ 3 ], which has a successful regularization term. The TV model can restore the corrupted image and preserve sharp edges [ 4 ]. However, it tends to produce staircase artifacts in smooth regions [ 5 ]. WebAug 5, 2024 · One involves a high-order total variation (TV) regularizer term in the corrected total variation L1 (CTVL1) model and is named high-order corrected TVL1 (HOCTVL1). This new model can not only suppress the defects of the staircase effect, but also improve the quality of image restoration.
