Parameters

image
Type: Emgu.CV..::..Image<(Of <(<'Bgr, Byte>)>)>
The image to search in
hitThreshold
Type: System..::..Double
Threshold for the distance between features and SVM classifying plane. Usually it is 0 and should be specfied 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
Type: System.Drawing..::..Size
Window stride. Must be a multiple of block stride.
padding
Type: System.Drawing..::..Size

[Missing <param name="padding"/> documentation for "M:Emgu.CV.HOGDescriptor.DetectMultiScale(Emgu.CV.Image{Emgu.CV.Structure.Bgr,System.Byte},System.Double,System.Drawing.Size,System.Drawing.Size,System.Double,System.Int32,System.Boolean)"]

scale
Type: System..::..Double
Coefficient of the detection window increase.
finalThreshold
Type: System..::..Int32
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. Use 2.0 for default
useMeanshiftGrouping
Type: System..::..Boolean
If true, it will use meanshift grouping.

Return Value

The regions where positives are found
