ICME 2012 is the thirteen in the series of ICME conferences that has been held annually since 2000, in various cities throughout the world. The success of this conference would not have been possible without the generous help of sponsors. Paper prizes and Student Travel Grants are sponsored by the National Information and Communications Technology Australia (NICTA), Microsoft Research, IBM Research,...
ICME has been a flagship international conference for the presentation of novel and fundamental research advances in the field of Multimedia since 2000. It is sponsored by four IEEE societies (IEEE Signal Processing Society, IEEE Communication Society, IEEE Circuit and System Society and IEEE Computer Society), and ICME 2012 is the 13th event. During the main conference (Jul. 10-12, 2012), the ICME...
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...
In this paper, a classification-based adaptive compression method for computer screen image is presented. This method firstly divides the computer Screen Image into 16x16 non-overlapping blocks, and then every block is classified into three types: text/graphic, pictorial and hybrid blocks based on the characteristics of histogram distribution and the number of colors. For complex text/graphic block,...
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...
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 4x4 blocks in the spatial domain. After decoding each layer, side information (SI) refinement process...
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. To...
The recent development of three dimensional (3D) display technologies has resulted in a proliferation of 3D video production and broadcasting, attracting a lot of research into capture, compression and delivery of stereoscopic content. However, the predominant design practice of interactions with 3D video content has failed to address its differences and possibilities in comparison the existing 2D...
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 requirement,...
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, Harris...
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...
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. This paper presents on-the-fly video watermarking...
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-tolerant...
Due to the increment of vehicles, the traffic jamming in cities becomes a serious challenge and the safety of people is threatened. Intelligent transportation system (ITS) and intelligent vehicles are critical to the efficiency of city transportation. In the area related with ITS and intelligent vehicles, moving vehicle detection and tracking are the most challenging problems. In this paper, we propose...
