I manually implemented pattern matching by applying pixel operations with a mask image. However, the performance seems slow. Is it possible to implement this feature using ImageEn or IEVision? Specifically, I want to perform pattern matching by ignoring the black areas of the mask image and only searching the remaining parts. I know that this functionality exists in OpenCV. Any advice on how to achieve similar results with ImageEn or IEVision would be greatly appreciated.

Hi

This is available with our matchTemplateMulti() method. Please see the example at:

Note also that if your mask is just transparency (i.e. an image with an alpha channel), you can just use the multiple result overload for the MatchTemplate helper:
