SoGrayscaleResconstructionProcessing engine
The SoGrayscaleResconstructionProcessing engine removes the light points in a dark image (case Dilation) or the dark points in a light image (case Erosion).
It performs a numerical reconstruction from a grayscale marker image into the grayscale input image.
Case Dilation
This case of use removes the light points in a dark image.
At each step the marker image is dilated by a structuring element of size 1. This algorithm is based on a recursive method whereby the minimum of the dilated image and the mask image is retained and used as the marker image at the next step. This operation is repeated until stability. The number of iterations depends on the input image and the marker image. As shown in the figure 1, peaks and ridges are levelled down, which results in a much more homogeneous output image.
Case Erosion
This case of use removes the dark points in a light image.
At each step the marker image is eroded by a structuring element of size 1. This algorithm is based on a recursive method whereby the maximum of the eroded image and the mask image is retained and used as the marker image at the next step. This operation is repeated until stability. The number of iterations depends on the input image and the marker image. As shown in the figure 2, the valleys are levelled up, which results in a much more homogeneous output image.
This algorithm is used by the SoHExtremaProcessing engine.
