Detailed Description

The ContoursQueryProc class performs edge detection followed by contour detection.

This processor uses Canny edge detection as a pre-processing step and then finds contours using the specified contour approximation method.

Member Function Documentation

bool ContoursQueryProc::process ( CVImage & prev_image )

overridevirtual

Processes the image using Canny edge detection followed by contour detection.

Parameters

prev_image The input/output image.

Implements ImageProc.

void ContoursQueryProc::setCannyPackage ( const std::pair< int, int > & p )

inline

Sets the Canny threshold pair used in edge detection.

Parameters

p	The pair of lower and upper thresholds.
