仿射不变特征提取 多尺度自卷积方法-The Multi-Scale Autoconvolution (MSA) method offers a novel way of approaching this problem. The method provides affine invariant features with only moderate computational complexity and does not require any other segmentation steps

上传一份MSA的MATLAB代码示例，希望能有帮助(Upload an example of MSA's MATLAB code, hoping to help)
