This example shows how to erode a binary image using the
Read a binary image into the workspace. Display the image.
BW1 = imread('circbw.tif'); figure imshow(BW1)
Create a structuring element. The following code creates a diagonal structuring element object.
SE = strel('arbitrary',eye(7))
SE = strel is a arbitrary shaped structuring element with properties: Neighborhood: [7x7 logical] Dimensionality: 2
Erode the image, specifying the input image and the structuring element as arguments to the
BW2 = imerode(BW1,SE);
Display the original image and the eroded image. Notice the diagonal streaks on the right side of the output image. These are due to the shape of the structuring element.
