To change a pixel region of an image in Matlab, you can follow these steps:
img
.imrect()
function to draw a rectangle interactively on the image or define the region programmatically using its coordinates.imcrop()
function, which takes the image and the rectangle coordinates as input parameters.Here is an example code snippet that changes the pixel region of an image using a Gaussian filter:
main.m398 chars19 lines
Note that in the code above, we used the round()
function to convert the floating-point rectangle coordinates returned by getPosition()
function into integer values required by array indexing.
