Block Category: Detection
Input Image Requirements: Binary
Description: The Find Contour block finds contours in a binary image based on the specified contour predicate.
The contour area is calculated as the smallest rectangle that contains the contour.
Area Threshold: Indicates the minimum pixel area for the threshold operation.
Contour Method: Indicates the contour approximation method.
Above Threshold: Detects all contours above the specified Area Threshold.
All: Detects all contours regardless of the threshold.
Below Threshold: Detects all contours below the specified Area Threshold.
Max Area: Detects the largest area contour.
Min Area: Detects the smallest area contour.
Contour Retrieval: Indicates the contour retrieval mode.
