MSER(删诞mauy stable extremal re舀ons)算法，提出一种对图像的尺度、旋转、仿

射变换更加稳定的区域不变量提取的算法。对于输入图像采用多尺度MSER提取算法，并对

提取的MsERS依据其灰度变换的平稳性对提取区域进行修正。提高了区域提取的可重复性

和匹配概率。-MSER (delete birth mauy stable extremal re scoop ons) algorithm is proposed to image the scale, rotation, affine transformation invariant more stable region extraction algorithm. For input images using multi-scale MSER extraction algorithm, and extracted MsERS according to their gray-scale transformation for the smooth extraction area to be amended. Region extraction improves the reproducibility and matching probability.
