Upon graduation design written MATLAB program to achieve the iXigUy image feature extraction, and do feature different light, different perspectives match under optimal JGPxzKQ difference calculation method, there are application programming source code matlab .m files and run picture file required.

-Write the gui matlab image processing function code, basically including the most basic image processing inside the process, such as reading the file, the geometric transformation of the vertical mirroring, translation, rotation, scaling　orthogonal transformation DFT, FFT, enYooZ , DWashT　anti-gray color processing, histogram equalization, global linear transformation, piecewise linear transformation, a nonlinear transformation index, the number of non-linear transform　image enhancement which increases the noise,kDTFmId method, sharpening, pseudo-color enhancement　 image segmentation inside the gray threshold, debugging can run.
