Yes i have done this to clip the image based on the shape file coordinates

the steps to that are:

1-try to the geoimread() function you can find it below enter the x and y coordinates as inputs( the x and y of the shapefile for example if you have it) geoimread(x1,y1) the output of this function is [xe,ye,values,..] so it will clip the image based on the bounding box of the shape file

2-after that try to use inpolygon(xe,ye,x1,y1) to clip the image based on the shape coordinates if it takes to much time try to search for another function which do the same job in the file exchange
