Now-a-days our environment is full of pollution. Pollution includes particles, water droplets, fog, smoke due to atmospheric absorption and scattering. Due to this the outdoor images suffer degradation, which is termed as Haze. The removal of this Haze is called Dehazing. In this paper, we propose a fast haze removal method, which is an improved version of an existing method using dark channel prior method proposed by He et al. [1]. In this method, we reduced the computational time by improving the method to estimate dark channel. Our proposed method uses a downsampled image and do not need a soft – matting process [2]. Experiments have proved that our proposed method is faster than existing He’s dark channel method with acceptable image quality.
