Digital image tampering operations destroy inbuilt fingerprints and create own new fingerprint in the tampered region. Considering the Internet speed and storage space, most of the images are circulated in the JPEG format. In a single compressed JPEG image, the first digits of DCT coefficients follow a logarithmic distribution. This distribution is not followed by DCT coefficients of DCT grid aligned...
The pattern growth approach of association rule mining is very efficient as avoiding the candidate generation step which is utilized in Apriori algorithm. This research is about the revisiting the pattern growth approaches to discover the different research works carried out to improve the performance using different criteria like header table dealing, item search order, conditional database representation,...
The treatment of chemical effluent is very complex with respect to its characteristics. To treat this effluent, different processes like biological, chemical and physiochemical can be applied based on its characteristics. Attempt was made to reduce COD and TSS. To obtain the optimum removal of COD and TSS, different combinations of coagulant and polyelectrolyte were applied at the laboratory scale...
