Resizes subs in subs/vals image representation by resizevals. imsubs is a 'bag of pixels' image representation which is useful for sparse arrays. This essentially repleces each sub by sub.*resizevals. The only subtlety is that in images the leftmost sub value is .5, so for example when resizing by a factor of 2, the first pixel is replaced by 2 pixels and so location 1 in the original image goes to location 1.5 in the second image, NOT 2. It may be necessary to round the values afterward. INPUTS subs - subscripts of point locations (n x d) resizevals - k element vector of shrinking factors OUTPUTS subs - transformed subscripts of point locations (n x d) DATESTAMP 29-Sep-2005 2:00pm See also IMSUBS2ARRAY
