  Houari Sabirin, Munchurl Kim

  IEEE Transactions on Multimedia. 06/2012;

  This paper presents a spatio-temporal graph based method of detecting and tracking moving objects by treating the encoded blocks with non-zero motion vectors and/or non-zero residues as potential parts of objects in H.264/AVC bitstreams.

[more] This paper presents a spatio-temporal graph based method of detecting and tracking moving objects by treating the encoded blocks with non-zero motion vectors and/or non-zero residues as potential parts of objects in H.264/AVC bitstreams. A spatio-temporal graph is constructed by first clustering the encoded blocks of potential object parts into block groups, each of which is defined as an attributed subgraph where the attributes of the vertices represent the positions, motion vectors and residues of the blocks. In order to remove false-positive blocks and to track the real objects, temporal connections between subgraphs in two consecutive frames are constructed and the similarities between subgraphs are computed, which constitutes a spatio-temporal graph. We show the experimental results that the proposed spatio-temporal graph based representation of potential object blocks enables effective detection for the small-sized objects and the objects with small motion vectors and residues, and allows for reliable tracking of the detected objects even under occlusion. The identification of the detected moving objects is determined as rectangular ROIs for which the ROI sizes and positions are adaptively adjusted to give the best approximation of the real shapes and positions of the objects.

[more] In this paper, we show that we can apply probabilistic spatiotemporal macroblock filtering (PSMF) and partial decoding processes to effectively detect and track multiple objects in real time in H.264|AVC bitstreams with stationary background. Our contribution is that our method cannot only show fast processing time but also handle multiple moving objects that are articulated, changing in size or internally have monotonous color, even though they contain a chaotic set of non-homogeneous motion vectors inside. In addition, our partial decoding process for H.264|AVC bitstreams enables to improve the accuracy of object trajectories and overcome long occlusion by using extracted color information.

  Signal Processing Magazine, IEEE. 08/2011;

  The ISO/IEC 23000-4 MPEG-A Part 4: The Musical Slide Show Application Format (MSS AF) standard is a storage format that specifies the synchronization of MP3 audio, Joint Picture Experts Group (JPEG) images and 3rd Generation Partnership Project (3GPP) timed text data in conjunction with the descript... [more] The ISO/IEC 23000-4 MPEG-A Part 4: The Musical Slide Show Application Format (MSS AF) standard is a storage format that specifies the synchronization of MP3 audio, Joint Picture Experts Group (JPEG) images and 3rd Generation Partnership Project (3GPP) timed text data in conjunction with the descriptions for image rendering animation using MPEG-4 Lightweight Application for Scene Representation (LASeR) scene representation. The creation information for MP3 audio and JPEG images, and the color and texture descriptions for JPEG images can also be generated for richer content description using MPEG-7 metadata. By specifying such a storage format, the standard enables different multimedia contents (in this case audio, images, texts and metadata) to be integrated into a single file in a structured way. In addition to this, the standard specifies the protection and governance schemes that enable flexible rights management of the contents seamlessly. Therefore, new business models can be created with the governed contents in secured and controlled manners according to their target applications. This article provides an overview of the technologies used in the standard as well as application examples to show its benefits and advantages.

[more] In this paper we present a novel method to detect and track moving objects in H.264/AVC bitstreams by processing motion vector and residue information. The encoded blocks with nonzero motion vectors and residues are first detected as moving object candidates. A spatio-temporal graph in video sequences is then constructed to represent groups of blocks in each frame and their associations to the other groups of blocks in subsequent frames. Identification and refinement of ROIs for moving objects being tracked are done by graph matching and adaptive ROI-size adjustment. The experimental results show that the proposed method can correctly identify real moving objects from frame to frame and can effectively detect small-sized objects and objects with small motion vectors and residues, as well as by recognizing moving objects even under occlusion.

[more] The Musical Slide Show Multimedia Application Format (MAF) which is currently being standardized by the Moving Picture Expert Group (MPEG) conveys the concept of combining several established standard technologies in a single file format. It defines the format of packing up MP3 audio data, along with JPEG images, MPEG-7 Simple Profile metadata, timed text, and MPEG-4 LASeR script. The presentation of Musical Slide Show MAF contents is made in a synchronized manner with JPEG images, timed text to MP3 audio track. Also, the rendering effect on JPEG images can be supported by the MPEG-4 LASeR script. This Musical Slide Show MAF will enrich the consumption of MP3 contents assisted with synchronized and rendered JPEG images, text as well as MPEG-7 metadata about the MP3 audio contents. However, there is no protection and governance mechanism for Musical Slide Show MAF which is the essential elements to deploy the sorts of contents. In this paper, to manage the Musical Slide Show MAF contents in a controlled manner, we present a protection and governance mechanism by using MPEG-21 Intellectual Property Management and Protection (IPMP) Components and MPEG-21 Rights Expression Language (REL) technologies We implement an authoring tool and a player tool for Musical Slide Show MAF contents and show the experimental results as well.
