    Usage of digital media has witnessed a tremendous growth during the last decades, as a result of their notable benefits in efficient storage, ease of manipulation and transmission. However these features make digital media vulnerable to copyright infringement, tampering and unauthorized distribution. In the last five years the protection of digital information has received significant attention wi... View full abstract»

    Robust, invisible watermarking of digital images or video very often has to satisfy a set of mutually conflicting requirements. These requirements include invisibility, robustness to image processing and geometric transformations, low false positive probabilities, high payload, fast detection and embedding, etc. In this paper we show how invariance to translations can be exploited to increase the ...

    A variety of digital watermarking applications have emerged recently that require the design of systems for embedding one signal (the "embedded signal" or "watermark") within another signal (the "host signal"). We develop a framework for analyzing achievable performance trade-offs of these systems among robustness, distortion, and embedding rate. We also describe a recently introduced class of emb...

    Transparent data embedding algorithms embed binary streams in host multimedia signals. The embedded data is perceptually inaudible to maintain the quality of the source data. The embedded data can add features to the host multimedia signal or provide copyright protection. We review developments and requirements in transparent data embedding techniques for audio signals. We describe our latest audi... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (665 KB)

    We address the problem of recovering 3D models from uncalibrated images of architectural scenes. We propose a simple, geometrically intuitive method which exploits the strong rigidity constraints of parallelism and orthogonality present in indoor and outdoor architectural scenes. We show how these simple constraints can be used to calibrate the cameras and to recover the projection matrices for ea... View full abstract»

    The proliferation of multimedia on the World Wide Web has led to the introduction of Web search engines for images, video and audio. On the Web, multimedia is typically embedded within documents that provide a wealth of indexing information. Harsh computational constraints imposed by the economics of advertising-supported searches restrict the complexity of analysis that can be performed at query ... View full abstract»

    Video as an entertainment or information source in consumer, military and broadcast television applications is widespread. Typically however, the video is simply presented to the viewer, with only minimal manipulation. Examples include chroma-keying (often used in news and weather broadcasts) where specific color components are detected and used to control the video source. In the past few years, ...

  • From 2D images to 2.5D sprites: a layered approach to modeling 3D scenes

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (790 KB)

    We propose a framework for modeling the appearance and geometry of 3D scenes as a collection of approximately 2D layers. Each layer corresponds to a view-based representation of a portion of the scene whose disparity across the given set of views can be approximately modeled using a planar surface. The representation of each layer consists of the parameters of the plane, a color image that specifi... View full abstract»

    We describe a method to completely automatically recover 3D scene structure together with a camera for each frame from a sequence of images acquired by an unknown camera undergoing unknown movement. Previous approaches have used calibration objects or landmarks to recover this information, and are therefore often limited to a particular scale. The approach of this paper is far more general, since ... View full abstract»

    We review and analyze different approaches to designing storage architectures for multimedia applications. We specifically examine scalability and cost of video on demand systems. By examining trends in storage technologies, we note the cost advantages of using hierarchical storage that include both secondary and tertiary storage devices over purely disk based video servers. Finally, we show how u... View full abstract»

    The traditional approach to software engineering is based on the waterfall model or some variation of this model. It is well known, however, that this approach is not particularly well suited to the production of one-of-a-kind or experimental systems due to fuzzy user requirements-users are not sure what can be accomplished. Since most multimedia applications are currently of this type, we must se... View full abstract»

    Multimedia is not a dream anymore. Nowadays we use images (e.g., GIF, JPEG, and BMP), videos (e.g., MPEG, AVI, and QuickTime), and sounds (e.g., MIDI and WAV) as well as alphanumerical information even on a personal computer. People whose research topics relate to computer network, operating system, real-time computing, user interface/HCI, or consumer products have been very active in developing m... View full abstract»

    Despite the growing importance of multimedia applications, we still know relatively little about how to specify, design and maintain this class of complex applications in a systematic manner. The concept of software architecture has recently emerged as a new way to improve our ability to effectively construct and maintain large-scale complex software systems. Under this new paradigm, software engi... View full abstract»

    Human computer interaction in the arena of multimedia is a vast topic. The sub-issues involved include the type of multimedia environment or application in question, the personal history and characteristics of the individual user, the reasons that he or she is employing the multimedia tool, and the surroundings in which he or she is working. In this paper, we look at the role that aesthetics plays... View full abstract»

    Traditionally usability holds the status of an art applied by limited, highly expert scientists and engineers intended to enhance the design of hardware and software for the ultimate benefit of the end user. In the creation of human computer interfaces, the usability engineer (or should we say interface artist) has at her disposal a number of techniques ranging from Wizard of Oz experiments to cog...

    The aim of usability evaluation is to establish if the users can effectively make use of what is being provided by an application. A general concern of the filed is to precisely establish what should be evaluated, and how it should be evaluated. This paper examines this issue specifically in the context of WWW and hypermedia applications. It is argued that usability for WWW applications should foc... View full abstract»
