The support values image is computed by c... Region-based adaptive anisotropic diffusion for image enhancement and denoising [作者：Wang, Y; Niu, RQ; Zhang, LP; Shen, HF,期刊：OPTICAL ENGINEERING, 页码：117007-117007 , 文章类型： Article，,卷期：2010年49-11] A novel region-based adaptive anisotropic diffusion (RAAD) is presented for image enhancement and denoising. The main idea of this algorithm is to perform the region-based adaptive segmentation. To this end, we use the e... Extended dot product representations of graphs with application to radar image segmentation [作者：Zhang, DM; Sun, DD; Fu, MS; Luo, B,期刊：OPTICAL ENGINEERING, 页码：117201-117201 , 文章类型： Article，,卷期：2010年49-11] Graph-based dimensionality reduction methods are popular in pattern recognition and machine learning. In contrast to the manifold learning approaches, the dot product representation of graphs (DPRG) seeks a solution t... Support vector machine-based facial-expression recognition method combining shape and appearance [作者：Han, EJ; Kang, BJ; Park, KR; Lee, S,期刊：OPTICAL ENGINEERING, 页码：117202-117202 , 文章类型： Article，,卷期：2010年49-11] Facial expression recognition can be widely used for various applications, such as emotion-based human-machine interaction, intelligent robot interfaces, face recognition robust to expression variation, etc. Previous stu... Keyframe labeling technique for surveillance event classification [作者：Saykol, E; Bastan, M; Gudukbay, U; Ulusoy, O,期刊：OPTICAL ENGINEERING, 页码：117203-117203 , 文章类型： Article，,卷期：2010年49-11] The huge amount of video data generated by surveillance systems necessitates the use of automatic tools for their efficient analysis, indexing, and retrieval. Automated access to the semantic content of surveillance vide... Picturewise inter-view prediction selection for multiview video coding [作者：Huo, JY; Chang, YL; Li, M; Yang, HT,期刊：OPTICAL ENGINEERING, 页码：117401-117401 , 文章类型： Article，,卷期：2010年49-11] Inter-view prediction is introduced in multiview video coding (MVC) to exploit the inter-view correlation. Statistical analyses show that the coding gain benefited from inter-view prediction is unequal among pictures. On... Imaging standoff detection of explosives using widely tunable midinfrared quantum cascade lasers [作者：Fuchs, F; Hugger, S; Kinzer, M; Aidam, R; Bronner, W; Losch, R; Yang, QK; Degreif, K; Schnurer, F,期刊：OPTICAL ENGINEERING, 页码：111127-111127 , 文章类型： Article，,卷期：2010年49-11] The use of a tunable midinfrared external cavity quantum cascade laser for the standoff detection of explosives at medium distances between 2 and 5 m is presented. For the collection of the diffusely backscattered light,...
