This test suite uses artificial images generated by "bombing" a blank image with gaussian blobs of various elongations and orientations. These images exhibit microtextures and generally favour algorithms which are sensitive to fine detail.
The bkgElong?? images are generated by the makeBrick
program with no mortar or rotation variation but with various
elongations. The mBkgElong?? tests repeat the
bkgElong?? tests but confound the problem with high contrast
mortar on a regular 10 by 10 pixel grid.
