Hybrid Smoothing and Sharpening Filters Using the Spatial Domain: Literature Review

Abstract

This study explores the field of image processing, emphasizing the difficulty presented by exterior artefacts on film, such as scratches, bruises, and cracks. Due to the limitations of mathematical analysis, unlike homogeneous noise, the shape and location of these faults must be determined manually during picture processing. The tight balance between retaining minute details and removing undesirable effects like noise makes the search for a universal filtering algorithm ongoing. The proposed work presents the enhancing through removing noises by applying proposed smoothing technique in order to eliminate these noises, this step leads to the blurring case, so for removing this blurring case, the output of this step is considered as an input to the next step through applying a proposed sharpening algorithm in the field of spatial domain, the final step is grouping all the processed frames for retrieving the processed video segment, in order to measure the performance of the proposed work, we compare the proposed work with others through some determined metrics.
