StereoBM class

Class for computing stereo correspondence using the block matching algorithm, introduced and contributed to OpenCV by K. Konolige.

This class implements a block matching algorithm for stereo correspondence, which is used to compute disparity maps from stereo image pairs. It provides methods to fine-tune parameters such as pre-filtering, texture thresholds, uniqueness ratios, and regions of interest (ROIs) to optimize performance and accuracy.

Constants

PREFILTER_NORMALIZED_RESPONSE → const int
Pre-filter types for the stereo matching algorithm. Uses normalized response for pre-filtering.
PREFILTER_XSOBEL → const int
Pre-filter types for the stereo matching algorithm. Uses the X-Sobel operator for pre-filtering.
