  • Abstract
  • Look Inside

 For the purpose of obtaining images which enables a reader to interpret easily and to minimize the possibility of overlooking lesions, we developed a structural enhancement processing technique in the HSI color space and color tone enhancement processing technique in the HSV color space. Each processing technique has its own advantages and disadvantages. The band enhancement processing in the HSI color space is regarded as providing easily readable diagnostic images, and the color tone enhancement by histogram flattening processing in the HSV color space is thought to minimize the possibility of overlooking lesions. These two image processing techniques can complement each other. By manipulating two methods of image processing, we would expect remarkable improvement in the diagnosis of early gastric cancer by identifying subtle structural and color tone differences.
