基于阈值的图像区域分割难点在于阈值的选择。目的：为HE染色病理切片区域分割提供通用稳定的算法，对感兴趣区域进行二值化。方法：选择前景色和背景色作为种子点，求取种子点的RGB值欧氏距离作为阈值，对图像二值化分割，与颜色深度的最大类间方差法、颜色深度迭代法等多种自适应获取的阈值二值化图像分割效果进行比较。结果：基于背景色和前景色种子点选择的颜色欧氏距离对图像二值化分割稳定性和准确性最好。结论：在区域划分合理的情况下，以种子点颜色深度的欧氏距离阈值进行二值化，可以提取到感兴趣区域。
基于閾值的圖像區域分割難點在于閾值的選擇。目的：為HE染色病理切片區域分割提供通用穩定的算法，對感興趣區域進行二值化。方法：選擇前景色和揹景色作為種子點，求取種子點的RGB值歐氏距離作為閾值，對圖像二值化分割，與顏色深度的最大類間方差法、顏色深度迭代法等多種自適應穫取的閾值二值化圖像分割效果進行比較。結果：基于揹景色和前景色種子點選擇的顏色歐氏距離對圖像二值化分割穩定性和準確性最好。結論：在區域劃分閤理的情況下，以種子點顏色深度的歐氏距離閾值進行二值化，可以提取到感興趣區域。

Threshold-based segmentation of image region has the difficult in threshold selection.Objective:Providing a general and stabilised algorithm for the segmentation of HE dyeing pathological section regions,and binarising the interested regions.Method:choosing the foreground and background colours as the seed points and calculating the RGB value Euclidean distance between the seed points as the threshold,then dividing the image in binarisation way;comparing it with the segmentation effects of several threshold binarised images adaptively obtained from the maximum between-cluster variance method of colour depth and the colour depth iterative method,etc.Results:the colour Euclidean distance based on background and foreground colours seed point selection has best stability and accuracy on image binarisation segmentation.Conclusion:under the circumstance of reasonable regional division,and binarising with Euclidean distance threshold of seed points’colour depth,the interested regions can be extracted.
