ディジタル画像の画像処理と画質変化 : ディジタル化のマトリクス数およびピクセルサイズ

概要

論文の詳細を見る
Research was undertaken on what was shown and what extent could be seen in the monitor presentation after the digitization of X ray photos and X ray images. It is well known that the spatial resolution of digitized images is determined by the sampling aperture size used for image digitization. In this study, the authors confirmed that only the objects whose thicknesses were 160 to 170% compared with the sampling aperture size could be resolved. For the reason mentioned above, during image digitization, the sampling is to be performed considering the fineness of the image to be resolved. The quantity of the data is varied with the fineness of the image.
