• File operator/threshold-grey8-grey8.crimp — part of check-in [0261f9ef4a] at 2012-01-06 23:21:56 on branch infinite-plane — Reworked the operators for local (i.e. spatially varying) thresholding to use the binop machinery to handle images with differing geometries. Dropped the primitives handling application of per-channel thresholds for multi-channel images and re-implemented them in Tcl, splitting and re-joining the input and results. As the resulting channels may have different geometries a bounding box is computed (see previous extension of "crimp::core), and all partial results then expanded to match this box before re-joining, through a new supporting command (matchgeo). These parts need testing. (user: andreask size: 406) [more...]
