提出一种基于可变性图谱局部约束的图像特征提取算法。运用3次样条插值算法逐行扫描特征模糊区域的突变像素点并进行替换，对每一个像素的灰度值与该行的灰度中值进行比较，对像素的分割进行有效的约束，保证模糊的突变像素点被分割算法有效排除。仿真实验结果表明，提出的改进算法能够有效提取出图像中的有效信息，同时节约了算法的执行时间，降低了复杂度。
提齣一種基于可變性圖譜跼部約束的圖像特徵提取算法。運用3次樣條插值算法逐行掃描特徵模糊區域的突變像素點併進行替換，對每一箇像素的灰度值與該行的灰度中值進行比較，對像素的分割進行有效的約束，保證模糊的突變像素點被分割算法有效排除。倣真實驗結果錶明，提齣的改進算法能夠有效提取齣圖像中的有效信息，同時節約瞭算法的執行時間，降低瞭複雜度。

Put forward a kind of based on local constraints variability map image feature extraction algorithm is proposed. Using three spline interpolation algorithm implementing mutation characteristics of fuzzy area pixel and replaced. Of each pixel gray value and its value in the comparison of the segmentation of pixel effective constraint. Ensure mutations fuzzy pixel is segmentation algorithm effectively ruled out. The simulation experimental results show that the improved algo-rithm can effectively extract the image of effective information, at the same time to save the execution time of the algo-rithm, and reduce the complexity.
