    Remote rendering of video games for 3DTV becomes a hot topic with the emergence of 3D-enabled mobile devices and cloud-based services. It is however a very challenging task that requires live encoding at very low latency for user interactivity as well as optimal encoding decisions for an acceptable QoE. One key-aspect is that most video games make use of a 3D engine, which is typically accelerated... View full abstract»

    The video coding standard H.264/AVC although possesses the advantage of higher coding efficiency compared to previous ones, it would result in a high computational complexity due to various block sizes motion estimation for multi-modes decision. In this paper, a hybrid inter-mode decision algorithm is presented, combining coded block pattern (CBP) with motion activity and Rate-Distortion (RD) cost... View full abstract»

    Distributed video coding (DVC) is an emerging coding paradigm, aiming at low complexity encoders. This paper proposes a new scheme for transform domain Wyner-Ziv (WZ) video codec, where the key and WZ frames are encoded in multiple layers. The layers of the each frame are generated by sub sampling the 4×4 blocks in the spatial domain. After decoding each layer, side information (SI) refinem... View full abstract»

  • Hidden Markov Model for Event Photo Stream Segmentation

    Publication Year: 2012, Page(s):25 - 30
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (489 KB) | HTML iconHTML

    A photo stream is a chronological sequence of photos. Most existing photo stream segmentation methods assume that a photo stream comprises of photos from multiple events and their goal is to produce groups of photos, each corresponding to an event, i.e. they perform automatic albuming. Even if these photos are grouped by event, sifting through the abundance of photos in each event is cumbersome. T... View full abstract»

    Off-line scanning, coding, transmission and remote animation of the human affect represents a possible processing pipeline for providing 3D immersion in virtual worlds. In this paper we target applications that make use of compact and scalable 3D representations of human affect and require close control over the local error introduced by lossy coding of the mesh geometry. To satisfy this requireme... View full abstract»

    Automatic assessment of image quality in accordance with the human visual system (HVS) finds application in various image processing tasks. In the last decade, a substantial proliferation in image quality assessment (IQA) based on structural similarity has been observed. The structural information estimation includes statistical values (mean, variance, and correlation), gradient information, Harri... View full abstract»

    Segmentation of 3D model models has applications, e.g., in mesh editing and 3D model retrieval. Unsupervised, automatic segmentation of 3D models can be useful. However, some applications require user-guided, interactive segmentation that captures user intention. This paper presents a supervised, local-geometry aware segmentation algorithm for 3D mesh models. The algorithm segments manifold meshes... View full abstract»

    In order to prevent piracy of digital media content, Digital Watermarking has emerged as a potential alternative to existing methods such as Digital Rights Management (DRM) based systems. For real-time watermarking applications, digital watermarking method should consume less time for embedding the watermark while remaining robust against attacks.

    Millions of photos are uploaded to social networking sites every day. However, the authenticity of these images has been severely questioned. Recent advances in image editing software have helped forged images spread widely. While these fake images leave no visual clues, they can still be detected by inspecting the traces left by the resampling process. In this paper, we propose a novel rotation-t... View full abstract»

    There is a need for video encoders to generate bitstreams of quality that matches human evaluation. This is often achieved by adopting perceptual quality metrics in video encoders. A huge body of work has been devoted to the development of perceptual video quality metrics that take the properties of human visual system into account. It is our interest in this paper to study how the existing video ... View full abstract»

    In Mode-Dependent Directional Transform (MDDT), Karhunen-CLoeve Transform (KLT) was employed to better compress the directional edges of intra prediction residues. The transform bases of MDDT were derived from the Singular Value Decomposition (SVD) of the intra prediction residues with the diversity of video characteristics. MDDT was mode dependent, but not video content dependent. It was expected... View full abstract»

    This paper proposes a novel three dimensional video (3DV) coding scheme, in which down-/up-sampling filters and asymmetrical prediction (ASP) are involved into the coding system. By using of the down-/up-sampling filters, the 3DV data volume requirement of the decoding capability limitations can be well satisfied. To further improve the coding efficiency, ASP is proposed which enables the inter-vi... View full abstract»

    This paper proposes a unidirectional encoder rate control (ERC) scheme in the interpolation based distributed video coding. As the encoder is complexity constrained, accurate estimation of number of bits to decode each bit plane is indeed difficult at the encoder. In case of under-estimation of the bits, correction of the errors in the decoded bit planes, by utilizing the available information, is... View full abstract»

    This paper proposed a coding mode selection method for video transmission over wireless networks. Unlike previous mode selection methods disregarding channel distortion or assuming constant packet loss rate (PLR), this method includes a cross-layer controller to collect both source and channel information. The mode selection process is formulated as a delay constrained distortion minimization prob... View full abstract»
