Dehazing technique for natural scene image based on color analysis and restoration with road edge detection

Abstract

Outdoor scene visibility deteriorates due to presence of haze or fog. Several dehazing techniques have found its application in fields of surveillance, detection, restoration and tracking. The techniques proposed till date are computationally complex and time consuming and thus not suited for real-time applications. The degraded images mostly suffer from reduced contrast. The technique proposed in this paper concentrates on fast restoration of scene color and contrast based on color analysis of the scene objects. As the image detail suffers due to haze, the road edge of an outdoor scene degrades significantly. Thus the proposed model has been extended to road edge detection and tracing along with on road obstacle detection.
