The computational complexity of H.264 video coding standard is two or three times higher than that of H.263 and MPEG-4. Especially, the operation of the entropy coding is one of the most time-consuming parts in the decoder. According to the characteristics of two-dimensional code table for CAVLC, a fast algorithm was proposed in H.264 decoder(More)
Polarimetric SAR interferometry (Pol-InSAR) is a radar remote sensing technique, that allows to extract forest heights by means of model-based inversion. Recently, there have been plenty of research on the retrieval of vegetation parameters by single frequency single baseline PolInSAR such as the ESPRIT method, three-stage inversion. However, these methods(More)
To settle the recognition task of handwritten Chinese characters, the authors put forward a method for handwritten Chinese character preclassification before character recognition. In this method, Neocognitron was used in extracting stroke features, then uses the Supervised Extended ART (SEART) to create some preclassification groups, and uses matching(More)
This paper presents a fuzz logic approach and similarity measure to efficiently perform handwritten Chinese character preclassification. After extracting stroke density features and using fuzzy rules to create some preclassification groups, we transform the characters in each group into fuzzy prototypes based on a nonlinear weighted similarity function by(More)
Polarimetric target decomposition is the most commonly used method of extracting information from polarimetric synthetic aperture radar (SAR) images. Coherent target decomposition methods are usually suitable for high-resolution images. Recently, Paladini reviewed coherent target decomposition methods and proposed a new approach, lossless and sufficient(More)
