Block Category: Filter
Input Image Requirements: None
Description: The Dilate block dilates an image using a specific structuring element. As the kernel passes over the image, bright regions within the image get larger (dilate).
Kernel Size: Specifies the Gaussian kernel size by width and height. The values must be odd, positive integers. For example, 9 x 9 or 5 x 3.
Cross: Indicates that a cross-shaped structuring element is specified.
Ellipse: Indicates that an ellipse-shaped structuring element is specified.
Rectangle: Indicates that a rectangular-shaped structuring element is specified.
In the following example, the letter j is dilated with a 51 x 51 structuring element. To improve viewing, the image is inverted and displayed on a black background.
