这里使用了双线性插值来处理极坐标转换到直角坐标下时，点不对称的问题，不过最后生成的图有一点问题，本来应该是一圈一圈的圆环，但是转化后的只有部分圆环了

rMin = 0.1 rMax =0.9

im2 = imread( ivus.bmp )

figure(4) imshow(im2)

imR2 = PolarToIm(im2, rMin, rMax, 300, 300)

figure(5) imshow(imR2, [0 255])

然后直接调用附件的function就可以了。



可否请各位大大修正一下这个程序，或者更简便的算法！~ 谢谢了！-There is a reference function code, use bilinear interpolation to convert polar coordinates to Cartesian coordinates, point asymmetric, but the final plans generated it was supposed to be a circle ring, but the conversion is only partially annular RMIN = 0.1　RMAX = 0.9　IM2 = imread (the　 ivus.bmp　)　Figure (4)　the imshow (IM2)　IMR2 = PolarToIm (IM2, Rmin, RMAX, 300, 300)　figure (5)　the imshow (imR2 [0 255])　then directly call the annex to function on it. Can I please greatly amend this program, or more simple algorithm! ~ Thank you!
