Turn greyscale into colorscale
質問
I am working on a Matlab script which applies a Laplacian filter to an image, and plots the result in greyscale. Do you have any suggestion on how to plot it using a colorscale instead?
Here is the code:
A=open('file.fits');
B=A.mcp;
H = fspecial('laplacian', 1); %fspecial creates a filter
I = imfilter(B, H);
figure;
imshow(I,[])
