imshow map image segmentation
显示 更早的评论
Hi,
I wrote a code but it does not show with scale I dont understand the reason.
Thank you
I=imread('mri.jpg');
J = imcrop(I,[197 180 130 165]);
%imshow(J);
[x,y]=size(J);
K=zeros(x,y);
cthresholdh=50;
cthresholdl=0;
for i=1:x
for j=1:y
if cthresholdh >= J(i,j) && J(i,j) >= cthresholdl
K(i,j)=1;
else
K(i,j)=0;
end
end
end
imshow(K,map);

What do you mean by "it does not show with scale"? Do you have any error? The question is not clear.
By the way, you don't need the loop nor x, y variables:
I=imread('mri.jpg');
J = imcrop(I,[197 180 130 165]);
%imshow(J);
K=zeros(size(J));
cthresholdh=50;
cthresholdl=0;
K(J >= cthresholdl & J <= cthresholdh) = 1;
imshow(K,map);

Can you upload your image ('mri.jpg')?

You just need to tune the rectangle in the imcrop call to adjust it to the result you want. For example:
I=imread('mri.jpg');
J = imcrop(I,[90 70 340 410]); %Changed
%imshow(J);
K=zeros(size(J));
cthresholdh=50;
cthresholdl=0;
K(J >= cthresholdl & J <= cthresholdh) = 1;
imshow(K)
Is this that you want? If not, specify what are you looking for in detail.
