    This paper presents the determination of bathymetric maps from the analysis of multispectral SPOT images. To this end, we have developed a multispectral segmentation method based on a hierarchical Markovian modeling including the unsupervised estimation of the model parameters. In each segmented region, an adaptive bathymetric inversion model is then applied in order to recover the water depth (ma... View full abstract»

    Digital watermarking is a labeling technique for digital images which embeds a code into the digital data so the data is marked. Watermarking techniques previously developed deal with on-line digital data and have been developed to withstand digital attacks such as image processing, compression and geometric transformations. We deal with printed images rather than on-line data. An important issue ... View full abstract»

    We describe effective channel coding strategies which can be used in conjunction with linear programming optimization techniques for the embedding of robust perceptually adaptive DCT domain watermarks. The main contributions lie in the proposal of a coding strategy based on the magnitude of a DCT coefficient, the use of turbo codes for effective error correction, and finally the incorporation of J...

    Video compression enables a number of applications by reducing the required bit rate needed to represent a video sequence, however the compressed video is much more susceptible to errors such as bit errors or packet loss. Conventional video compression standards employ an architecture which we refer to as single-state systems since they have a prediction loop with a single state (e.g. the previous...

    We propose a novel architecture for scalable video coding, namely, progressive fine granularity scalable (PEGS) coding, which can provide a high coding efficiency along with good bandwidth adaptation and error recovery properties. Unlike the fine granularity scalable (FGS) coding in the MPEG-4 proposal, some of the enhancement layers in a current frame are predicted from a high quality enhancement... View full abstract»

    Cited by:  Papers (10)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (360 KB)

    An information-theoretic model for image watermarking and data hiding systems is presented. The fundamental capacity limits of these systems are determined by the statistical model used for the host image, by the distortion constraints on the data hider and the attacker, and by the information available to the data hider, to the attacker, and to the decoder. We consider wavelet statistical models ... View full abstract»

    We formulate a model for probability distributions on image spaces. We show that any distribution of images can be factored exactly into conditional distributions of feature vectors at one resolution (pyramid level) conditioned on the image information at lower resolutions. We would like to factor this over positions in the pyramid levels to make it tractable, but such factoring may miss long-rang... View full abstract»

    Most consumer cameras use a single CCD sensor and a colour filter array (CFA) to take colour pictures. The array samples the red, green, and blue colour planes on sparse sampling lattices that are not coincident and not necessarily orthogonal. The “raw” images are then interpolated and post-processed to prepare them for display. Existing multiframe enhancement methods use the post-proc... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (304 KB)

    An important halftoning problem faced in the design of many color printers and copiers is to represent a 24-bit color image by a small number of preset output colors, generally at a higher spatial resolution. We propose dividing the input and output image into corresponding small blocks, calculating each input block's color average, and then determining a set of the printing colors for the corresp...

    A new approach to multispectral image compression is introduced where the intra- and cross-band correlations are jointly exploited in a surprisingly simple yet very effective manner. The proposed compression algorithm maps the multispectral image set into a virtual 2-dimensional array and applies a scalar image coding algorithm to the virtual array. Thus, the spatial correlation and the spectral c... View full abstract»

    In the MPEG standard, motion estimation (ME) is used to eliminate the temporal redundancy of video frames. This ME is the most time-consuming task in the encoding of video sequences and is also the one using the most power. Using low-bit images can save the power of ME and a conventional architecture fixed to a certain bit width is used for low-bit motion estimation. It is known that there is a tr...

    The proliferation of digital images creates problems for managing large image databases, indexing individual images, and protecting intellectual property. This paper introduces a novel image indexing technique that may be called an image hash function. The algorithm uses randomized signal processing strategies for a non-reversible compression of images into random binary strings, and is shown to b... View full abstract»

    Analyzing the structure of the family of cost functions that are minimum when the classifier outputs are equal to the class probabilities, we found that all of them can be expressed as sum of a generalized entropy measure and an error component. This suggests a novel algorithm for classification that uses both labeled an unlabeled data and is based on the following idea: use labeled data to minimi... View full abstract»

    Nowadays, content-based retrieval of video material is based on the availability of meta-data linked to it. Current approaches to automatically extract these data start from a temporal segmentation of the audio-visual material, that is, a location of the camera shot transitions. Although abrupt transition detection is a problem almost solved, success on gradual transition detection is still very l... View full abstract»

    Wavelet-domain hidden Markov models (HMMs) have been proposed and applied to image processing, e.g., image denoising. We develop a new HMM, called local contextual HMM (LCHMM), by introducing the Gaussian mixture field where wavelet coefficients are assumed to locally follow the Gaussian mixture distributions determined by their neighborhoods. The LCHMM can exploit both the local statistics and th... View full abstract»
