  1. In the table, WNZH-DMST is abbreviated as DMST for compactness. The given values for JPEG compression, AWGN, and MedianCut denote the strongest attacks that the concerned scheme can successfully counteract. The ‘Ok’ for GaussFilt. (i.e., Gaussian filtering) and sharpening implies that the DMST or DPT survive all default attacks in StirMark 4.1.
