Performance Analysis of Single Image Fog Expulsion Techniques

Haze removal techniques are widely used in various computer vision applications like object detection, tracking, target recognition, and video surveillance. Therefore, in this paper, the classification of different fog removal techniques is presented. Further, recent dehazing algorithms related to each category are analyzed for the restoration of atmospherically degraded images. However, the performance of the different algorithms is evaluated based on the most commonly used image quality assessment parameters. Hence, different comparison parameters utilized for the evaluation of the performance of the various dehazing algorithms are also discussed. Finally, the qualitative and quantitative comparison of the various state-of-art defogging algorithms and research scope for further improvement is discussed.
