Neighbourhood operation on 2D images with an extra image

The pattern loops over all pixels in the image and the extra image and applies the neighbourhood functor to the pixels. The result is written to the corresponding position in the result image.

Instantiations of the pattern are invoked via

• HxImageRep::neighbourhoodOpExtra(HxString,HxImageRep,HxTagList&)

Instantiation is done via the HxImgFtorNgb2dExtra functor, with the following template parameters:

• DstImgSigT is the signature type of the destination image
• SrcImgSigT is the signature type of the source image
• ExtraImgSigT is the signature type of the extra image
• NgbT is the type of the neighbourhood functor

The requirements for the NgbT parameter and an example of its use are given in the sections on variations:

• 1 phase, coordinate enumerated neighbourhood operation with an extra image
• 1 phase, loop neighbourhood operation with an extra image
• 2 phase, loop neighbourhood operation with an extra image
• N phase, loop neighbourhood operation with an extra image

Tags for NgbT variations:

• PhaseCategory : HxTag1Phase or HxTag2Phase or HxTagNPhase
• IteratorCategory : HxTagCnum or HxTagLoop

• HxImageData member : HxImageData::neighbourhoodOpExtra(HxImageData*,HxImageData*,HxString,HxTagList&)
