The timing at which Bz1 and Bz2 are turned off is critical for specification of the brain and palp fates.
As described above, the gene circuit consisting of Bzl and Bz2 temporally controls ZicL expression in the neural lineage.
3D, knockdown of Bz1 and Bz2 results in loss of the palp, a rudimentary anterior placode, and ectopic induction of brain in its place.
In the case of our test image, the BZ2 variant generated the best results, with a compression factor reaching 1.3 and an efficiency level of 0.2 for any of the 3 filters used.
In the case of the Generalized Laplacian pyramid, improvements are easily visible (while testing only the BZ2 compression method): the compression factor is better than the best run of the simple Laplacian pyramid process, while efficiency reaches a value of 0.3.
