    Recursive rectilinear tessellations like quadtree are widely used in image coding, but a regular tessellation, despite simple geometry, may not suit image compression because it is too rigid to reflect the scene structure of an image. The paper presents a new image pyramid formed by adaptive, tree-structured segmentation to be a framework of a predictive multiresolution image coder. Subjectively a... View full abstract»

    Previously, Markov random field (MRF) model-based techniques have been proposed for image motion estimation. Since motion estimation is usually an ill-posed problem, various constraints are needed to obtain a unique and stable solution. The main advantage of the MRF approach is its capacity to incorporate such constraints, for instance, motion continuity within an object and motion discontinuity a... View full abstract»

    Introduces efficient pipeline architectures for the recursive morphological operations. The standard morphological operation is applied directly on the original input image and produces an output image. The order of image scanning in which the operator is applied to the input pixels is irrelevant. However, the intent of the recursive morphological operations is to feed back the output at the curre... View full abstract»

  • Multiscale corner detection by using wavelet transform

    Publication Year: 1995 , Page(s): 100 - 104

    A multiscale corner detection algorithm based on the wavelet transform of contour orientation is proposed. It can utilize both the information of the local extrema and modulus of transform results to detect corners and arcs effectively. The ramp-width of contour orientation profile, which can be computed using the transformed modulus of two scales, reveals the difference between corner and arc and... View full abstract»

  • Successive elimination algorithm for motion estimation

    The correspondence presents a fast exhaustive search algorithm for motion estimation. The basic idea is to obtain the best estimate of the motion vectors by successively eliminating the search positions in the search window and thus decreasing the number of matching evaluations that require very intensive computations. Simulation results demonstrate that although the performance of the proposed al... View full abstract»

  • Spectral characteristics and motion-compensated restoration of composite frames

    Publication Year: 1995 , Page(s): 95 - 99
    Cited by:  Papers (1)

    The practice of superimposing the fields of a frame is applied in various fields, for example, thermographic and biomedical imaging. The pictures obtained in this way, which are termed composite frames, are severely degraded if the scene's objects are not perfectly still. The restoration of composite frames affected by motion-induced blurring requires the ability to estimate the field displacement... View full abstract»

  • Perceptual evaluation of the mean-square error choice of regularization parameter

    Publication Year: 1995 , Page(s): 107 - 110
    Cited by:  Papers (3)

    A formal perceptual study shows that the perceptually optimal choice of regularization parameter varies from the minimum mean-square error parameter as a function of the original image, the point-spread function, and the signal-to noise ratio (SNR). However, further studies show that this variation has only a slight effect on the perceived quality of the restoration View full abstract»

  • Invariant matching and identification of curves using B-splines curve representation

    Cited by:  Papers (50)

    There have been many techniques for curve shape representation and analysis, ranging from Fourier descriptors, to moments, to implicit polynomials, to differential geometry features, to time series models, to B-splines, etc. The B-splines stand as one of the most efficient curve (surface) representations and possess very attractive properties such as spatial uniqueness, boundedness and continuity,...

  • Motion estimation based on time-sequentially sampled imagery

    Determining the parameters of motion within a time-varying scene is an important problem in such fields as computer vision, motion compensated video coding, and tracking. Most motion estimation algorithms operate on image data that has been sampled in both space and time. However, very little work has been done to investigate the impact of the underlying sampling strategy on the motion estimation ... View full abstract»

  • Constrained nonlinear optimization approaches to color-signal separation

    Separating a color signal into illumination and surface reflectance components is a fundamental issue in color reproduction and constancy. This can be carried out by minimizing the error in the least squares (LS) fit of the product of the illumination and the surface spectral reflectance to the actual color signal. When taking in account the physical realizability constraints on the surface reflec... View full abstract»

    A new model-based approach to digital halftoning is proposed. It is intended primarily for laser printers, which generate “distortions” such as “dot overlap”. Conventional methods, such as clustered-dot ordered dither, resist distortions at the expense of spatial and gray-scale resolution. The proposed approach relies on printer models that predict distortions, and rather t... View full abstract»
