This function is similiar to cvCalcBackProjectPatch. It slids through image, compares overlapped patches of size wxh with templ using the specified method and stores the comparison results to result

Namespace: Emgu.CV.GPU
Assembly: Emgu.CV.GPU (in Emgu.CV.GPU.dll) Version: 2.4.2.1777 (2.4.2.1777)

	IntPtr stream
)

Parameters

image
Type: System..::..IntPtr
Image where the search is running. It should be 8-bit or 32-bit floating-point
templ
Type: System..::..IntPtr
Searched template; must be not greater than the source image and the same data type as the image
result
Type: System..::..IntPtr
A map of comparison results; single-channel 32-bit floating-point. If image is WxH and templ is wxh then result must be W-w+1xH-h+1.
method
Type: Emgu.CV.CvEnum..::..TM_TYPE
Specifies the way the template must be compared with image regions
gpuMatchTemplateBuf
Type: System..::..IntPtr
Pointer to GpuMatchTemplateBuf, if you use stream, you must specify a GpuMatchTemplateBuf
stream
Type: System..::..IntPtr
Use a Stream to call the function asynchronously (non-blocking) or IntPtr.Zero to call the function synchronously (blocking).
