Morphological Image Operations

About The Operations

Morphological operations are techniques used in image processing that modify the geometry of features in an image. This app demonstrates the two fundamental operations: Erosion and Dilation.

Erosion & Dilation

Erosion "erodes" or shrinks the boundaries of bright regions. It is useful for removing small bright noise spots. Dilation "dilates" or expands the boundaries of bright regions. It can be used to fill small holes and connect disjoint objects.

Kernel

The operation is performed by a Kernel (or Structuring Element) which is a small matrix of pixels. You can choose the shape and size of the kernel, which changes its effect. A larger kernel results in a more pronounced operation.
