Description

TCVN_FRM_GRID

Extracts ROIs by laying a regular grid of stRoiSize cells (see TcVnParamsFindRois) over the image and keeping only cells that contain sufficient texture. This method supports both binary and grayscale images.

TCVN_FRM_CONNECTEDCOMPONENTS

Extracts ROIs using connected-component analysis. The binary image is dilated to bridge nearby components, and then labeled.
