Hi everyone,

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

The way I want to do this to replace the coordinate values. I have for example the coordinates ranging from [34 70] to [34 80] in my image, which I would like to replace with the values from the coordinate 10 above so these would be [34 60] to [34 70]. This is to remove an artifact within my image and I have no clue how to do this but to replace each pixel 1 by 1 however, I would like to make a loop statement so that I can repeat this along the other columns.

Any help on this would be greatly appreciated.

try with more size to see it, for example :

yourimage(34:44,70:80,:)=yourimage(34:44,60:70,:)

Thank you this works

Do you know how I can make this a loop statement so that I can repeat along the different columns as my artifact is in a diagonal position and it will take me a long time to change each specific column.
