dehaze

The implementations of dark channel prior haze removal and fast haze removal by using Qt and OpenCV.

Introduction

Fog-degraded images are usually unclear and reduce the visual effects because the air contains a lot of particulate matter and makes the obtained images degrade. For solving the degraded problems including low contrast, weak color etc., I have made a simple program to demonstrate the process of dehaze by using dark channel prior algorithm and fast dehaze algorithm.

Addition

In my implementation, using the sampling technique to faster the processing.
