Parameters

image
Image<(Of <(<'Bgr, Byte>)>)>
The image to search in
hitThreshold
Double
The threshold for the distance between features and classifying plane.
winStride
Size
Window stride. Must be a multiple of block stride.
padding
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)"]

scale
Double
Coefficient of the detection window increase.
groupThreshold
Int32
After detection some objects could be covered by many rectangles. This coefficient regulates similarity threshold. 0 means don't perform grouping.

Return Value

The regions where positives are found
