    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»

  • An image restoration method using IFS

    Publication Year: 2000, Page(s):774 - 777 vol.3

    This paper proposes a new image restoration method based on the iterated function system (IFS). The proposed method can restore images contaminated by impulsive noise according to self-similarity represented by the IFS parameters. Since the IFS is usually used for image coding, it has never been applied to image restoration; and it cannot be utilized for image restoration as it is. In order to ada... View full abstract»

  • The iterative deconvolution of linearly blurred images using non-parametric stabilizing functions

    Publication Year: 2000, Page(s):770 - 773 vol.3
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (284 KB)

    An iterative solution to the problem of image deconvolution is presented. The previous image estimate is pre-filtered using a stabilizing function that is updated based on current error and noise estimates. Noise propagation from one iteration to the next is reduced by the use of a second, regularizing operator resulting in a hybrid iteration technique. Further, error terms are developed that shed...

    This paper proposes a novel probabilistic framework for semantic indexing and retrieval in digital video. The components of the framework are probabilistic multimedia objects (multijects) and a network of such objects (multinet). The main contribution is a Bayesian multinet which enhances the detection performance of individual multijects and supports inference of concepts that are not observed di... View full abstract»

    We describe a novel method of removing additive white noise of known variance from photographic images. The method is based on a characterization of the statistical properties of natural images represented in a complex wavelet decomposition. Specifically, we decompose the noisy image into wavelet subbands, estimate the autocorrelation of both the noise-free raw coefficients and their magnitudes wi... View full abstract»

    The use of wavelet thresholding has been investigated with much success in the areas of denoising, density estimation, image restoration, etc. Significant attention has been given to wavelet thresholding as a signal denoising technique. The algorithm is simple and provides good results. The 2-D discrete wavelet transform (DWT) and its relatives have been used to generalize the denoising methods to... View full abstract»

    In this article, we propose an object tracking method using a neural network which represents the shape of an object based on the object's color information. We previously proposed a specific form of multiple-layered neural network which has a suitable structure to represent an object's shape. This network (shape representation network, SRN) originally was developed to deal with black and white im... View full abstract»

    Many content-based image retrieval (CBIR) systems utilize image segmentation for enabling the user to perform object-level database querying. We propose an integrated segmentation technique for interactive image retrieval, that is reasonably accurate and fast. An initial over-segmentation is generated by finding the dominant color modes in the global histogram of the image using the mean-shift alg... View full abstract»

    A technique using the inherent feature map of the underlying image as the watermark is proposed in this work. First, the binary feature map is extracted as watermark and partitioned into blocks. Secondly, neighboring feature map blocks are blended and encrypted for insertion. On the receiver side, the feature map from the received image is extracted again and compared against the recovered waterma... View full abstract»

    The visual interpretation of ultrasound brain images is a proven method to detect the white matter damage at an early stage. A problem, common to all medical ultrasound images, is the presence of speckle noise, which not only complicates the visual interpretation of images, but also quantitative measurements. This paper proposes a new filter that removes a significant amount of speckle noise from ... View full abstract»

    Direct processing of JPEG images based on DCT coefficients could avoid computationally intensive full decoding and large memory storage. In this paper, we exploit the inherent information extracted from DCT coefficients to achieve unsupervised segmentation of image objects. First, a maximum entropy fuzzy clustering (MEFC) algorithm is proposed to achieve a coarse segmentation based on DCT-DC coeff... View full abstract»

    A texture descriptor invariant to translation, rotation and scale changes is presented in this paper. A power spectral image is obtained by using the DFT to extract the proposed descriptor for the translation invariance of a given texture. The power spectral image is scale-normalized by a cut-off frequency on the power spectral image that is calculated as the total energy inside a circle with its ... View full abstract»

    The techniques commonly used in image coding (JPEG, MPEG, …) have as the main objective to compress as much as possible while retaining most of the information. These methods are often based on the use of the discrete cosine transform (DCT) and the wavelet transform (WT). Our purpose is to consider the necessary redundancy to achieve a good reception in the case of heavy interruptions of bi... View full abstract»

    Through its demixing operation, the potential use of independent components analysis (ICA) for multi-frequency polarimetric SAR imagery enhancement and feature extraction is demonstrated. A compound PCA-ICA neural network model is proposed, which consists of two levels of processing.

    Dimensionality reduction methods are of interest in applications such as content based image and video retrieval. In large multimedia databases, it may not be practical to search through the entire database in order to retrieve the nearest neighbors of a query. Good data structures for similarity search and indexing are needed, and the existing data structures do not scale well for the high dimens... View full abstract»

    We introduce a mixed fixed-length coding (FLC) and variable-length coding (VLC) technique to improve the error resilience of the upcoming JPEG2000 image coding standard. Our proposed method operates on quantized subband coefficients, and produces a bit-stream with both FLC and VLC codewords. Higher error resilience is achieved by eliminating the error propagation within FLC sections, which in gene... View full abstract»

    Translation-invariant denoising was introduced by Coifman and Donoho (1995) to overcome Gibbs-type phenomena produced by transform-domain shrinkage estimators in the vicinity of signal discontinuities. Shrinkage estimators are in general not shift-invariant. Shift-invariant denoising consists of a simple averaging of the shrinkage estimates over a family of cyclic spatial-shifts of the image.

    This paper presents an exhaustive search algorithm for block matching motion estimation. The proposed algorithm reduces the computational load with successive elimination of non-candidate blocks in the search window. The proposed algorithm locates the global optima as located by the full search block-matching algorithm. This computational reduction leads to low-power VLSI implementation of the alg...

    This paper proposes a new image based rendering technique called concentric mosaic for virtual reality applications. It is constructed by capturing vertical slit images when a camera is moving around a set of concentric circles. Concentric mosaic allows the user to move freely in a circular region and observe significant parallax and lighting changes without recovering the geometric and photometri... View full abstract»
