Parameters

srcs
Type: array<Emgu.CV..::..Image<(Of <(<'Gray, TDepth>)>)>>[]()[][]
Source images, all are of the same size and type
patchSize
Type: System.Drawing..::..Size
Size of patch slid though the source images.
method
Type: Emgu.CV.CvEnum..::..HISTOGRAM_COMP_METHOD
Comparison method, passed to cvCompareHist.
factor
Type: System..::..Double
Normalization factor for histograms, will affect normalization scale of destination image, pass 1 if unsure.

Type Parameters

TDepth
The type of depth of the image

Return Value

Type: Image<(Of <(<'Gray, Single>)>)>
Destination back projection image of the same type as the source images
