This letter proposes a novel scheme for spatial steganalysis based on contrast of residuals (CoR). After selecting complex blocks from an uncompressed image by a fluctuation function, the residuals are calculated from the selected blocks and the whole image after applying diverse filters. The CoR is represented as an angle and the norm of residuals is considered as the corresponding weight of angle,...
At present, study on performances of tyre is mainly focused on such characteristics as pressure, temperature and frictional coefficient, etc, however, with the neglect of texture analysis on tyre surface. In fact, during the course of driving, the latter has recorded large amount of information about acting features from environment, vehicle and tire self, whose forces together act on formation of...
