Fpga Implementation of Haze Removal Algorithm for Image Processing

Haze removal is a difficult problem due the inherent ambiguity between the haze and the underlying scene. All images contain some noise due to sensor error that can be amplified in the haze removal process. A number of methods have been proposed for haze removal. In this paper proposes a simple but effective image prior to remove haze from a single input image. By using single image it removes haze and improving the contrast ratio. The first approach is to dehaze the image using haze removal algorithm. This approach essentially treats and removes haze. The second approach is to dehaze the haze image using edge detector. Run haze removal algorithm using system generator model, which automatically generates VHDL code and create .bit file which is downloaded on FPGA hardware through JTAG cable. The dehaze image result is then observed on VGA monitor. This algorithm is less time consuming and provides faster time execution for real time image and video processing. The resultant dehaze image is more reliable, clear and more accurate and intelligible.
