Color Laparoscopic Image Region Segmentation after Contrast Enhancement Including SRCNN by Image Regions

摘要

As one of image pre-processing method to detect, recognize, and estimate lesion or characteristic region in medical image processing, there arc many studies improved performance and precision of processing by contrast enhancement, or super-resolution. However, it, is not clarified how condition is better to apply these methods. Therefore, we experimented and discussed on affect for color laparoscopic image quality by the difference of contrast enhancement method. As a result, we obtained knowledge of high similarity among patterns of adaptive histogram equalization in three methods. However, under these conditions, in the case of considering the region segmentation, it is not clarified how processing precision is better. In this paper, first we processed the contrast enhancement for the color laparoscopic frame image cut from surgery video under laparoscopy. Next, we processed super-resolution for generated image. Finally, we compared and discussed by Peak Signal to Noise Ratio (PSNR), Structural SIMilarity (SSIM), and texture features for contrast.
