Namespace: OpenCvSharp
Assembly: OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax
public static bool RunHaarClassifierCascade( CvHaarClassifierCascade cascade, CvPoint pt, bool start_stage )
Parameters
- cascade
- Type: OpenCvSharpCvHaarClassifierCascade
Haar classifier cascade. - pt
- Type: OpenCvSharpCvPoint
Top-left corner of the analyzed region. Size of the region is a original window size scaled by the currenly set scale. The current window size may be retrieved using cvGetHaarClassifierCascadeWindowSize function. - start_stage
- Type: SystemBoolean
Initial zero-based index of the cascade stage to start from. The function assumes that all the previous stages are passed. This feature is used internally by cvHaarDetectObjects for better processor cache utilization.
Return Value
Type: Booleanpositive value if the analyzed rectangle passed all the classifier stages (it is a candidate) and zero or negative value otherwise.
