Abstract EN
In this paper, we develop a novel linear singularity representation method using spatial K-neighbor block-extraction and Haar transform (BEH).
Block-extraction provides a group of image blocks with similar (generally smooth) backgrounds but different image edge locations.
An interblock Haar transform is then used to represent these differences, thus achieving a linear singularity representation.
Next, we magnify the weak detailed coefficients of BEH to allow for image enhancement.
Experimental results show that the proposed method achieves better image enhancement, compared to block-matching and 3D filtering (BM3D), nonsubsampled contourlet transform (NSCT), and guided image filtering.
