	int groupThreshold
)

Parameters

image
GpuImage<(Of <(<'Gray, Byte>)>)>
The GpuImage 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
Mock parameter to keep CPU interface compatibility. Must be (0,0).
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
