Rotate part of an image?
조회 수: 3(최근 30일)
I have a .tiff file that I read into matlab as a .mat file and plot. When I plot the matrix, the image I am actually interested in (part no including purple triangle edges around the image) is rotated. How do I first remove the purple border around the image (highlighted in light blue in the attached jpeg file) and then take the image and rotate it by 30 degrees counterclockwise to make the image flat? The outside purple part of the image I to remove from the image has a value of 0 and color purple according to the colorbar.
