grey-level image

基本解釋

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(zhuǎn)換為OHTA顏色空間中的灰度圖像，用閾值法實(shí)現(xiàn)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(duì)圖像中的高灰度區(qū)和灰度劇變區(qū)，應(yīng)用圖像局部均值和方差自適應(yīng)調(diào)節(jié)增強(qiáng)系數(shù)。
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?jǐn)?shù)布朗運(yùn)動(dòng)形成的（分形）灰度表面，并用這種灰度表面的分形維數(shù)來(lái)刻畫它的紋理粗糙程度。

灰度圖像
By doing this, the new method combined surface fitting with watershed transform solves the grey-level image segmentation in complex background well.
最后,本文將曲面擬合法和分水嶺變換法有機(jī)的結(jié)合起來(lái)實(shí)現(xiàn)復(fù)雜背景下的灰度圖像分割。
