以像素的灰度值為特徵向量進行編碼，利用直方圖熵法準則函數作為適應度函數，採用基於排名的選擇操作，以一定的概率進行算術交叉和變異，並結合聚類分析設定種群的聚類中心對細胞圖像進行遺傳聚類分割。 -
The image enhancement problem for degraded images with less gray levels and low contrasts
灰度等級少、對比度低的降質圖像增強問題。 -
By adjusting the gray value of pixels after histogram equalization, this thesis puts forward a method called histogram equalization of preserving gray scales. it enriches the gray levels and dispels the infection of the gray level amalgamation to some extent
通過調整直方圖均衡化后像素的灰度值，給出了保留灰度級的直方圖均衡化方法，豐富了圖像的灰度層次，一定程度上消除了灰度級合併對圖像帶來的影響。 -
One is based on bitmap. this way is in light of the mapping between gray levels of the bitmap and the height of the terrain. in other words, the minimum gray point is the lowest terrain and the maximum gray point is the summit
一種是基於位圖的生成方法，該方法是依據位圖的灰度等級與地形的高程之間的映射關系，來創建地形的模型；也就是位圖的最低灰度對應地形的最低點，位圖的最高灰度對應地形的最高點。 -
Because of the shortage of traditional unsupervised algorithm, three algorithms are proposed in the paper based on the spatial information of the difference image and the clustering characteristic of 2 - d histogram formed by pixel gray levels and the local average gray levels. the proposed algorithms segment the pixels of
本文針對典型演算法存在的不足，充分利用差異圖象灰度空間分佈信息和差異圖象灰度-鄰域平均灰度二維直方圖的聚類特性提出了三種非監督變化檢測方法，將差異圖象所有像素分成變化和非變化兩個類別。 -
The light spot image thresholding part of the suite puts forward the iterative algorithm to gain the best threshold by comparing, which could perfectly hold the original image feature. in the extracting the light spot image features part, the algorithms on calculating the coordinates of the " energy distribution barycenter " in the 256 gray levels image and the " geometric - center " in the binary image are adopted respectively and so on
如在對光斑圖像進行二值化的過程中，通過比較發現使用迭代法求出最佳閾值的演算法能夠較好的保留原圖像的特徵。在對光斑圖像進行特徵提取的過程中，分別採用了對256級灰度的光斑圖像求其「能量分佈的重心」坐標；對光斑的二值化圖像求其「形心」坐標等演算法。 -
The gray level maximum has not been changed in the classical fuzzy enhancement method proposed by s. k. pal, so this kind of image enhancement method is not fit for the enhancement problem of degraded images with less gray levels and low contrasts ; the fact that the value domain of membership function of gray levels is not normalization form, i. e. [ 0, 1 ], is another disadvantage of the traditional fuzzy enhancement means
但是由pal提出的經典模糊增強方法並沒有改變圖像灰度等級的上界，所以這種增強方法不適合於灰度等級少、對比度低的圖像增強問題，並且這種經典模糊增強方法的隸屬度函數值域不具有通常的規范形式，即[ 0 ， 1 ]區間。 -
