MatchTemplate function

[egorovp]

Problem:

Error in the dimensions of the output map in CTS(OpenVX Conformance Test Suite).

Quote from standard:

The output of the template matching node is a comparison map. The output comparison map should be the same size as the input image.

Why in CTS the output map has following dimensions:

result_width = source_width - template_width + 1 ,
result_height = source_height - template_height + 1

instead of (source_width, source_height) ?

Still looking at this one--please be patient. 😃

The spec seems to have stated it wrong. Sliding the template within the image will result in the width/height as calculated in the CTS. This is how it is derived in Sample Implementation as well (see vxCalculateBufferSizes() in kernels/c_model/c_matchtemplate.c). The spec needs to be corrected.

@fbrill3, thank you for your responses. Looking forward to update
