Shot detection is the first and important stage of video analysis. In this paper, an effective shot change detection system using multi-stage algorithm is presented. First the isolated clips were founded in a given video sequence, and corresponding three dimensional wavelet transform representations of these image sequences were obtained. Then shot detection of multi-scale and controllable precision...
Based on the principle of improving shape memory effect (SME) in Fe-based alloys by directional precipitation of carbides induced by γ/ɛ interfaces, the effects of deformation temperature on the γ/ɛ interfaces, carbides precipitation after ageing and SME of an Fe13.53Mn4.86Si8.16Cr3.82Ni0.16C alloy were investigated. The results show that through controlling the amount and direction of γ/ɛ interfaces,...
