http://user.qzone.qq.com/413548407我要对这幅图像先进行投影,再对其投影图像进行插值来消除了那些伪影(就是那是闪光地方的发射黑线),之后再反投影回来
P1=imread('x1.BMP');
P=double(P1)/255;
figure(3),imshow(P)
theta = 0:1:179; [R1,xp] = radon(P,theta);
figure(4), imagesc(theta,xp,R1); colormap(hot); colorbar
xlabel('\theta'); ylabel('x\prime');
imwrite(R1,'x3.BMP')
I= iradon(R1,1);
figure(10);
imshow(I);
imwrite(I,'x4.BMP')
但是投影的图像我没办法就其插值.(最近邻插值,双线性插值还有双立方插值都不行)
麻烦那个高手出来指导我下,小生感激不尽
