Fast connected-component labeling
WebCCLabel. Fast implementation of connected-component labelling in Swift. Currently only 4-connectivity is supported. In CcLabel, call the labelImageFast function to label your image. Optionally, the bounding … WebAbstract. We present two optimization strategies to improve connected-component labeling algorithms. Taking together, they form an efficient two-pass labeling algorithm that is fast and theoretically optimal. The first optimization strategy reduces the number of neighboring pixels accessed through the use of a decision tree, and the second one ...
