Feature reduction and payload location with WAM steganalysis
WAM steganalysis is a feature-based classifier for detecting LSB matching steganography, presented in 2006 by Goljan et al. and demonstrated to be sensitive even to small payloads. This paper makes three contributions to the development of the WAM method. First, we benchmark some variants of WAM in a number of sets of cover images, and we are able to quantify the significance of differences in ...
متن کاملEeciently Implementing Slg Resolution
SLG is a table-oriented resolution method that is gaining increasing attention due to its ability to combine the deductive database, non-monotonic reasoning and logic programming paradigms. SLG resembles SLD in that it admits a tuple-at-a-time resolution method, so it can make use of many of the techniques developed in implementing SLD over the past decade. Indeed, a program can contain any mix...
متن کاملCHAT is O(SLG-WAM)
CHAT offers an alternative to SLG-WAM for implementing the suspension and resumption of consumers: unlike SLG-WAM, it does not use freeze registers nor a complicated trail to preserve their execution environments. CHAT also limits the amount of copying of CAT, which was previously put forward as an alternative to SLG-WAM. Although experimental results show that in practice CHAT is competitive w...
متن کاملA Few Logs Suuce to Build (almost) All Trees (ii)
Inferring evolutionary trees is an interesting and important problem in biology that is very di cult from a computational point of view as most associated optimization problems are NP-hard. Although it is known that many methods are provably statistically consistent (i.e. the probability of recovering the correct tree converges on 1 as the sequence length increases), the actual rate of converge...
متن کاملCAT : the Copying Approach to
The SLG-WAM can be characterized as a sharing approach to implementing tabling: the execution environments of suspended computations are intersperced in the WAM stacks. Stacks are frozen using a set of freeze registers and the WAM trail mechanism is extended so that the suspended computations can be resumed. This technique has a reasonably small execution overhead, but is not easy to implement ...
