To convolve one image with another image in MATLAB, you can use the conv2
function.
Here's an example of convolving an image with a Gaussian filter:
main.m272 chars12 lines
In this example, fspecial
is used to create a Gaussian filter with a size of 5x5 and a standard deviation of 1. The image img
is then converted to double precision and the first channel is convolved with the Gaussian filter using conv2
. Finally, the result is converted back to uint8 format and displayed using imshow
.
