  "message": "Further improvements on the hybrid dwt/dct expt\n\nModifies the scanning pattern and uses a floating point 16x16\ndct implementation for now to handle scaling better.\nAlso experiments are in progress with 2/6 and 9/7 wavelets.\n\nResults have improved to within ~0.25% of 32x32 dct for std-hd\nand about 0.03% for derf. This difference can probably be bridged by\nre-optimizing the entropy stats for these transforms. Currently\nthe stats used are common between 32x32 dct and dwt/dct.\n\nExperiments are in progress with various scan pattern - wavelet\ncombinations.\n\nIdeally the subbands should be tokenized separately, and an\nexperiment will be condcuted next on that.\n\nChange-Id: Ia9cbfc2d63cb7a47e562b2cd9341caf962bcc110\n",
