MATLAB: How to replace a pixel value of the image with another value

coordinatesctimage analysisimage processingindexingmatrixpixelsreplacevalues

Hi everyone,

I have a pixel value of my image, which I would like to replace with another pixel value from the same image.

The way I want to do this to replace the coordinate value. I have the coordinate [34 71] in my image, which I would like to replace with the value from the coordinate [34 55]

Any help on this would be greatly appreciated.

MATLAB: Replace repetitive values in a matrix with another value

x = [1 2 3 3 3 3 3 4 5 3 3 3 6 3 7] data
idxrep = ~diff([-inf,x]) %pad with -inf and identify areas of zero change (~)
x(idxrep)=nan; %replace with NaN, or whatever

If you chose the NaN route and want an awesome way to fill them:

y = inpaint_nans(x)
