Watermarking compressed video stream over Internet

Watermarking compressed video stream over Internet

引用

Asia-Pacific conference on communications

作者： D. Ghosh K. Ramakrishna Department of Electronics and Communication Engineering Indian Institute of Technology Guwahati India Digital Signal Processing Group Emuzed India Private Limited Bangalore India

As Internet is gaining popularity day by day throughout the globe, it has become necessary to protect the copyright ownership of multimedia data distributing in Internet. The technique generally used for the purpose is watermarking. This has motivated the ongoing research in watermarking. In this paper, we develop an oblivious scheme for watermarking MPEG coded video stream over Internet. The inter-frame similarity present in a video sequence is exploited to calculate the watermark to be embedded. Watermark corresponding to a region in the current frame is obtained from its best match in the previous frame. The watermark is embedded during the coding process thereby keeping the overall computational overhead minimum. The algorithm has been tested in terms of the watermarked video quality and its capability in extracting the author's signature (watermark bits). We have also tested the robustness of the proposed scheme against noise attack. Results obtained demonstrate the efficiency of the proposed method.

The advancement of visual technology and the maturity of display process technique enable monitor industry to put forth multi-view stereo display systems, which allow consumers to watch 3D images with naked eyes. However, due to the insufficient 3D original videos, we are unable to achieve the end of enjoying 3D effect through stereo display. Therefore, this paper aims to provide a real-time algorithm for 2D-to-3D conversion, through which 2D video will be accompanied with a depth image so that one can obtain 3D images through auto stereoscopic display. The proposed algorithm focuses on the depth of background scenes and the active objects, while extracting depth information from the two for complete processing of depth generation. Since the production of depth information always requires heavy computation, we adapt VIA's embedded systems with a 1.6GHz CPU, as well as nVIDIA CUDA (compute unified device architecture) technology which contains 256 core processor with the clock rate of each processor up to 950MHz. When accompanied with our proposed CUDA parallelization technique, the experimental results show an 83% of recognition rate for depth image, and a display rate of 32.52 frames per second in Full-HD format (1920×1088 pixels).

International conference on Computer Vision (ICCV)

作者： F. Heitger R. von der Heydt Communication Technology Laboratory Swiss Federal Institute of Technology Zurich Switzerland Department of Neurology University Hospital Zurich Zurich Switzerland

The detection of occluding contours in images of 3-D scenes is a fundamental problem of vision. The authors present a computational model of contour processing that was suggested by neurophysiological recordings from the monkey visual cortex. The model uses convolutions and nonlinear operations, but no feedback loops. Contours are defined by the local maxima of the responses of a contour operator that sums a representation of contrast borders and a grouping signal. The grouping consists of convolving a representation of key-points, such as T-junctions, corners, and line ends, with a set of orientation selective kernels, and a nonlinear pairing operation. The grouping scheme is selective based on whether the configuration of key-points is consistent with the interpretation of occlusion. The resulting contour representation includes an indicator of figure-ground direction. It is shown that the model reproduces illusory contours in accurate agreement with perception and generates representations of occluding contours on images of natural scenes that are more complete and less cluttered by spurious connections of foreground and background than those obtained by conventional edge detection operators.< >

UDesignIt: Towards social media for community-driven design

International conference on Software Engineering (ICSE)

Online social networks are now common place in day-to-day lives. They are also increasingly used to drive social action initiatives, either led by government or communities themselves (e.g., SeeClickFix, ***, mumsnet). However, such initiatives are mainly used for crowd sourcing community views or coordinating activities. With the changing global economic and political landscape, there is an ever pressing need to engage citizens on a large-scale, not only in consultations about systems that affect them, but also involve them directly in the design of these very systems. In this paper we present the UDesignIt platform that combines social media technologies with software engineering concepts to empower communities to discuss and extract high-level design features. It combines natural language processing, feature modelling and visual overlays in the form of “image clouds” to enable communities and software engineers alike to unlock the knowledge contained in the unstructured and unfiltered content of social media where people discuss social problems and their solutions. By automatically extracting key themes and presenting them in a structured and organised manner in near real-time, the approach drives a shift towards large-scale engagement of community stakeholders for system design.

IEEE conference on Vehicular Technology (VTC)

作者： James Nightingale Qi Wang Christos Grecos Audio Visual Communications & Networks Group School of Computing University of the West of Scotland Paisley UK

There has been a significant amount of recent research in the computer networking community on the emerging wireless networking paradigm known as Mobile Networks; while the real-time image processing community have expended much effort on the development of scalable video encoding techniques and investigating the multipath streaming of real-time multimedia content. This work draws together the key elements of recent research in each of these areas and proposes a novel scheme for the multipath delivery of scalable video streams to users within multihomed mobile networks. We provide a hardware-based, multihomed mobile networks testbed and propose OPSSA, an optimised path selection and scheduling algorithm for use in multihomed mobile networks. Experimental results show our algorithm to outperform the representative algorithms when measured using the Peak Signal to Noise Ratio (PSNR) metric.

ASIC design of a progressive vector quantizer

ASIC design of a progressive vector quantizer

MILCOM, Military communications conference

作者： G.A. Rasche K.S. Thyagarajan K. Bakhru Cubic Defense Systems San Diego State University USA

The authors describe the architecture of a real-time progressive full-search vector quantizer (VQ) suitable for VLSI implementation. Because of the large memory and ALU requirements of a single VQ, the compression is performed in stages. Each stage generates a codebook index, a difference vector, and total pixel error squared. The encoder chip is partitioned into master/slave portions dividing the codebooks and computational requirements between the two ASICs (application-specific integrated circuits). Because the system is modular, several encoder stages can be cascaded to achieve a higher-quality reconstruction. The VQ is progressive in the sense that each additional stage of encoding produces better visual quality. The authors also describe the architecture of a completion chip which can be used in conjunction with several encoders to realize a single VQ.< >

In e-learning area, the content development method is one of the most important research topics. This paper proposes a presentation method of visual contents (a text, a still image) in synchronization with narration (sound content) and a pointer to make the efficiency of the resource allocation of cognitive memory capacity increase, and make the transmitted amount of information maximize, based on a human's cognitive-information-processing model "dual channel model." Under various contents presentation environment {(1)narration, (2) text (with narration / without narration), (3) still images, (4) still images + text (with narration / without narration), (5) video, and (6) video + text} in e-learning, we performed some control experiments (measure the point of fixation for e-learning students by an eye mark recorder, memorization and a contents understanding test and the questionnaire) with or without pointer. The results showed the validity of this model and the effectiveness of the proposed content development method in e-learning.

Relevance feedback based on SVM classifier shows a good performance recently but the finite feedback counts limited by user's patience and the small sample size problem are not solved well, Co-SVM does a good job in solving these problems but still has some flaws. We propose three strategies to try to improve this algorithm: (1) different kernel functions are used to characterize the color and texture visual similarities; (2) a new method is proposed to caculate the confident scores of the contention samples; (3) a bunch of the most irrelevant images with the highest confident score are added into the labeled images to extend the size of labeled data while choosing a bunch of images for user labeling. Experimental results verify the superiority of our method over Co-SVM.

Operation of AUVs or other platforms that rely upon robust communications for navigation and mission critical tasks is facilitated by the use of on-board data compression. Data compression eliminates redundancy of transmitted information and therefore improves the efficiency of the entire mission. In some applications, acoustic and non-acoustic sensor information is acquired and processed to produce a visual representation for ease of human-in-the-loop analysis and interpretation. Many image and data compression methods are currently in development. Emphasis has been placed on achieving high efficiency as characterized by compression ratio while retaining the least error between the original image and the compressed image. Although some algorithms produce excellent results, computational complexity, and hence speed of compression or decompression, can become a limiting factor in real-time use depending upon the capability of the on-board processor. This paper describes the implementation of a high performance image compression transform using a dedicated DSP processor and supporting computer host. The system architecture and strategy for efficient code implementation are described. Example performance measures are presented for non-acoustic undersea studies. Future plans and developments for specialized applications are also discussed.

Early detection of Alzheimer’s disease (AD) is important at the initial stage to provide prior treatment and control. In traditional diagnostic methods, medical doctors perform manual AD checking by asking patients to repeat several round of text reading and game exercises. The quantification of this manual assessment can be subjective due to the profession experience and it requires a further verification using the brain imaging. In this paper, an automated digital AD assessment method using Virtual Reality (VR) console is proposed to evaluate patient’s condition by tracking their eye movement during text reading. First, the eye movement pattern is captured using VR console during text reading. The recorded eye movement is then converted into frequency domain to study its frequency components during reading process. The simulation of AD symptom is set up by prompting subjects to read their familiar native language and unfamiliar language. As a result, the experiment shows that there are significant differences in eye movement patterns between native and unfamiliar language reading. The group of subjects reading unfamiliar language have random eye movement in less efficient visual processing. This pattern is similar to the patients who suffer in the AD symptom. In addition, the frequency features are extracted to study its correlations with reading comprehension performance in order to detect the early AD condition.
