Comparison of the processing times of median filtering by the AP and the PIM. The images denote the subjects of the experiments in this paper. The AP and the PIM symbolize the processing times for median filtering by the AP and the PIM, respectively. The reduction ratios denote the processing times in the PIM resulting from comparisons of the three images from the experiments conducted in this study

Image	AP (sec.)	PIM (sec.)	Reduction ratio (%)
Lena	8.004326	1.288066	83.91
Cancer	6.719369	1.245627	81.46
Skin	7.862324	1.287875	83.62
