To remove noise in an image using imerode
in MATLAB, first, the image needs to be converted into a binary image with a proper threshold. Then, the noise can be eliminated by performing morphological erosion on the image. Here's an example code snippet:
main.m433 chars22 lines
In this example, a noisy image is first converted into a binary image using a threshold of 128. Then, a 3x3
square structuring element is created using strel
function. Finally, the morphological erosion operation is performed on the binary image using the structural element created earlier. The result is shown in a side-by-side comparison with the original binary image using the imshow
function with proper titles.
