Infrared Image Quality Improvement Through Guided Filter Based Novel Edge-Detection, Edge-Preservation and Smoothening Filter Algorithm

摘要

This paper proposes a novel edge-detection, edge preservation and smoothening filter for infrared images. The proposed method consists of two steps: extracting the edges of Infrared (IR) image using modified canny operator and edge-preserving and smoothening using bilateral/guided filter. Experimental result shows the effectiveness of the proposed method in terms of the visual quality.
