In keeping with Marianne Hirsch＇s notion of ＂postmemory＂, this paper argues that cinema, as a visual form of artistic mediation, has an especially strong impact on the spectator, because it triggers affective, tactile, and bodily responses. Hence, the efficacy of generating an ethics of remembrance of sexually-related violence, based on cinematic aesthetics, which the author terms here ＂cinememory＂. The paper focuses on a sub-genre of Holocaust-related films： coming-of-age films, which explore in different ways the lasting implications of growing-up in the shadow of sexualized trauma; the unconscious transmission of memories and tactile experiences, related to the ubiquity of sexual violence during the Holocaust.展开更多

In this paper, an information fusion based scheme is presented to obtain 3-D information of human head. Structured light technology is employed to measure depth. For the special reflection areas,in which the structured light stripe can not be detected directly, the shape of the structured light stripe can be calculated from the corresponding contour. By fusing the information of structured light and the contours, the problem of reflectance influence is solved, and the whole shape of head,including hair area, can be obtained. Some good results are obtained.展开更多
