M output, N input pixel operation

The pattern loops over all pixels in the N input images and applies the pixel functor to each pair of N pixels. The result set of M values is written to the corresponding positions in the M result image.

Instantiations of the pattern are invoked via

• HxImageRep::MNPixOp

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

• DstImgsSigT is the signature type of the destination images
• SrcImgsSigT is the signature type of the source images
• MNpoT is the type of the multi pixel functor

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

• Translation invariant M output, N input pixel operation
• Translation variant M output, N input pixel operation

Tags for MNpoT variations:

• TransVarianceCategory : HxTagTransVar or HxTagTransInVar

• HxImageData member : HxImageData::MNPixOp
