Term: Thresholding, adaptive

Adaptive thresholding, also called dynamic or local thresholding, establishes the threshold level for determining whether to convert to white or black at a regional level. The region sampled and method of evaluation vary between applications. Adaptive thresholding at a pixel level (in comparison with neighboring pixels) can yield highly superior results compared to global thresholding, particularly for images with varying levels of regional contrast differences.
