FindMaxStableExtremalRegions


Module: FoundationPro

Segments an image by binarizing it with many different thresholds and by looking which blobs appear "stable".

Applications

Most frequently used for finding correspondence points between two images.
Name Type Range Description
Input value inImage Image Input image
Input value inDelta Integer 1 - 255 Area variance is calculated against ancestor with color difference of delta
Input value inMinArea Integer 0 - Minimum area of stable region
Input value inMaxArea Integer 0 - Maximum area of stable region
Input value inMaxVariation Real 0.0 - Maximum area variance with containing larger region specified by delta parameter, for region to be considered as stable
Input value inMinDiversity Real 0.0 - Minimum area diversity that region must have in order to be stable when compared to stable regions within it
Input value inConnectivity RegionConnectivity
Output value outRegions RegionArray
