sentences:  Having done this for each point, the R-table will fully represent the template object.Also, since the generation phase is invertible, we may use it to localise object occurrences at other places in the image.For each edge pixel "x" in the image, find the gradient "ɸ" and increment all the corresponding points "x+r" in the accumulator array "A" (initialized to a maximum size of the image) where r is a table entry indexed by "ɸ", i.e., "r(ɸ)".
