Gait is thought to be the most effective feature for human recognition in the distance. For optimal performance, the feature should include as many different types of information as possible, so in this paper, we present an integrated feature, which integrates motion feature and shape feature based on the Bayesian theory. For motion feature, we use shape variation-based frieze pattern (SVB frieze...
A new sub-pixel edge detection algorithm based on multi-scale is introduced. Edge of the images is interpolated at different fuzzy scales. Positions obtained under different scales are interpolated further at the same position to obtain the sub-pixel edge. The sub-pixel edge is fitted to get the size of a circular which is measured at higher precision than traditional method. Validity of the algorithm...
The effects of metallic ion (Al, Ti, or La) doping in HfO2 or ZrO2 on the behaviors of oxygen vacancies (V0) such as the formation energy, density of states, and migration energy were investigated by using first principles calculations. The calculations show that, 1) the doping causes an upward shift of deep V0 levels; 2) dopant radius has a weak impact on the relaxed formation energy of V0 (Ejv)...
9-round impossible differentials of SNAKE-2 are found due to the simple linear transformation in its round function, and 10 to 12-round SNAKE-2 are attacked by using these impossible differentials.
The GMTI (Ground Moving Target Indication) performance for circular scanning SAR (Synthetic Aperture Radar) equipped on slow platform was analyzed in this paper. The characteristics of SAR equipped on slow platform and the GMTI application were descript in the beginning, and the circular scanning mode was advanced to resolve the low azimuth imaging efficiency of the slow platform borne SAR. Then the...
