ABSTRACT

Since the haze removal algorithm using dark channel prior was introduced, many researches forimproving processing speed have been addressed even if it presented impressive results. Remarkable one is using median dark channel prior. Although it has been considered as a veryattactive method, processing speed is as low as ever. So, a parallel memory model which is suitablefor SIMD architecture processing haze removal on high-definition images in high-speed is introduced in this paper. The proposed parallel memory model allows to access n pixelssimultaneously. It is also support stride 3, 5, 7, and 11 in order to execute convolution maskoperations, e.g., median filter. The proposed parallel memory model can therefore support enoughdata bandwidth to process the algorithm using median dark channel prior in high-speed.
