Sharpness Enhancement and Denoising of Image Using L1-Norm Minimization Technique in Adaptive Bilateral Filter
Shahla Naureen Khan | Chhabikiran Sao
Abstract: In Image processing, Image restoration technique plays a vital role. Removing mixed noise from images is a challenging problem. This paper presents a novel technique of Image sharpening and Denoising using the L1-norm minimization technique in Adaptive Bilateral Filtering. The objective of this paper is to explore the advantage of new technique over the existing ones. This employs comparison of results obtained using both L1 and L2-norm minimization techniques. In this paper, we consider Least Absolute Deviation (L1) method for image restoration in ABF. This method finds application in many areas due to its robustness as compared to Least Squares method (L2).
