Morphological Reconstruction
Morphological reconstruction is another major part of morphological image processing. Based on dilation, morphological reconstruction has these unique properties:
- Processing is based on two images, a marker and a mask, rather than one image and a structuring element
- Processing repeats until stability; i.e., the image no longer changes
- Processing is based on the concept of connectivity, rather than a structuring element.
The following sections describe the functions in the toolbox that are based on morphological reconstruction:
- Marker and Mask - This section describes the fundamental reconstruction function,
imreconstruct, and provides background information about morphological reconstruction.
- Pixel Connectivity - This section describes how pixel connectivity affects morphological reconstruction.
- Flood-Fill Operations - This section describes how to use the
imfill function, which is based on morphological reconstruction.
- Finding Peaks and Valleys - This section describes a group of functions, all based on morphological reconstruction, that process image extrema, i.e., the areas of high- and low-intensity in images.
