常見例句雙語例句At first, a color image is transformed into a grey-level image in OHTA color space, and segmented by constant threshold value;首先將圖像轉換為OHTA顏色空間中的灰度圖像，用閾值法實現了圖像分割；For regions with high grey-scale level or with tensely variable grey level, the image enhancement coefficients shall be adaptively controlled based on local mean value and variance.針對圖像中的高灰度區(qū)和灰度劇變區(qū)，應用圖像局部均值和方差自適應調節(jié)增強系數。By taking the image to be compressed as a grey-level surface of some fractal brown motion, the fractal dimension of this surface gives out a good description of its texture characteristics.把灰度圖像看作是某種分數布朗運動形成的（分形）灰度表面，并用這種灰度表面的分形維數來刻畫它的紋理粗糙程度。 返回 grey-level image
