HOGDescriptorDetectMultiScale Method
Performs object detection with increasing detection window.

Namespace:  Emgu.CV
Assembly:  Emgu.CV.World (in Emgu.CV.World.dll) Version: (
public MCvObjectDetection[] DetectMultiScale(
	IInputArray image,
	double hitThreshold = 0,
	Size winStride = null,
	Size padding = null,
	double scale = 1.05,
	double finalThreshold = 2,
	bool useMeanshiftGrouping = false


Type: Emgu.CVIInputArray
The image to search in
hitThreshold (Optional)
Type: SystemDouble
Threshold for the distance between features and SVM classifying plane. Usually it is 0 and should be specified in the detector coefficients (as the last free coefficient). But if the free coefficient is omitted (which is allowed), you can specify it manually here.
winStride (Optional)
Type: System.DrawingSize
Window stride. Must be a multiple of block stride.
padding (Optional)
Type: System.DrawingSize
scale (Optional)
Type: SystemDouble
Coefficient of the detection window increase.
finalThreshold (Optional)
Type: SystemDouble
After detection some objects could be covered by many rectangles. This coefficient regulates similarity threshold. 0 means don't perform grouping. Should be an integer if not using meanshift grouping.
useMeanshiftGrouping (Optional)
Type: SystemBoolean
If true, it will use meanshift grouping.

Return Value

Type: MCvObjectDetection
The regions where positives are found
