  • Multi-camera Calibration Based on Iterative Factorization of Measurement Matrix

    We propose a joint multi-camera calibration algorithm based on iterative factorization of the measurement matrix. The matrix is composed of homographies between the model plane and its images. Rescaling and decomposition of the measurement matrix are implemented with series of 3D reconstruction techniques. Since these techniques deal well with the missing data, the model plane disposed in the cali... View full abstract»

  • Encoder Rate Control for Pixel-Domain Distributed Video Coding without Feedback Channel

    Distributed video coding (DVC) is a new video coding technique which has low encoder complexity and good error resilience. Rate control is one of the most important problems in DVC. In order to allocate an optimal number of parity bits for the current frame, most distributed video coders use a feedback channel (FC) to perform rate control at the decoder. However, using feedback channel can increas... View full abstract»

  • Analysis and Synthesis of Spatial Parameters Using MDCT

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (250 KB) | HTML iconHTML

    We present a method of analyzing and synthesizing spatial parameters using only modified discrete cosine transform (MDCT). Combing it with modified discrete sine transform (MDST) enables spatial parameters representation. And instead of direct transforming, MDST spectra can be perfectly built from neighboring MDCT spectra by a conversion matrix, which is highly diagonal and can be approximated by ...

    In the scalable video coding extension of H.264 standard, the concept of inter-layer prediction is adopted to reduce the redundancy between the base layers and the enhancement layers. Thus, additional coding modes should be calculated during the macroblock mode decision procedure at the enhancement layers. It increases the computational complexity and may obstruct its practical applications. A fas... View full abstract»

    Due to the limitation of computing complexity, it is difficult to apply the H.264 deblocking filter to low-end terminals. Although some technologies to optimize it have been proposed, the complexity is still high for real time implementation. Considering that deblocking filter is applied to all of the vertical and horizontal edges of 4times4 blocks but only some of them actually need to be filtere... View full abstract»

    Owing to the popular usage of Photoshop, PS images which are processed by Photoshop or other similar software nowadays emerge increasingly. PS images may be misfortunes to steganalysis. The similarities and differences between PS and stego images are analyzed in this paper, and a method is proposed to classify the natural, PS and stego images. The first-scale diagonal subband obtained by wavelet t... View full abstract»

  • An Innovative Variational Level Set Model for Multiphase Image Segmentation

    Publication Year: 2009, Page(s):41 - 44
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (401 KB) | HTML iconHTML

    In this paper, a new model based on variational level set method for segmenting multiphase images is proposed. Its energy functional is based on the level set functions and the regional characteristics functions. It can deal with changes in curves' topology and be extended to multiphase image segmentation models which are based on other schemes for region competition as well. The gradient flow of ...

  • An Efficient Coding of Intra Picture Prediction Modes for H.264/AVC

    Video coding standard H.264/AVC employs nine-mode directional spatial prediction for intra picture coding. It predicts pixels to be encoded from previously decoded neighboring pixels within current picture. This paper presents an efficient coding method for H.264 intra picture prediction modes to enhance coding efficiency performance. The proposed method improves prediction of intra picture most p...

    In this paper, we present an adaptive intra-frame rate-quantization (R-Q) model for H.264/AVC. The R-Q model, which is a generic relationship among the quantization value, data bits and the frame complexity, provides a mechanism to properly select the quantization value for an intra frame at a given target bit rate. Based on the proposed intra-frame R-Q model, a bit allocation scheme for intra fra... View full abstract»

    The study integrates the resonance principle of quantum physics and random walks concept to analyze the image multi-understandings. The quantum model of the photo and bounded electron interaction is recruited to simulate the machine image understanding problems. The pixel or the unit cell of the image will be resonance when the pixel or the unit cell satisfied the given quantum condition. Besides,... View full abstract»

    A precise simulative estimate of a channel distortion model is proposed by analyzing characteristics of error propagation. This model can well be combined with the advantages of the recursive optimal per-pixel estimate model and the channel simulative estimate model. A specific packet loss-rate channel distortion is calculated by a few special channel simulators first. Then other packet loss-rate ... View full abstract»

    Although motion recovery for limited field-of-view (FOV) cameras has been studied for decades under the pin-hole projection, few attentions have been paid on omni-directional cameras. Omni-directional cameras are usually constituted complicatedly, especially some are made of several limited FOV cameras, and thus motion recovery for omni-directional cameras is more different. In this paper, an algo... View full abstract»
