    A description of the transferable belief model, which is used to quantify degrees of belief based on belief functions, is given. The impact of open- and closed-world assumption on conditioning is discussed. The nature of the frame of discernment on which a degree of belief will be established is discussed. A set of axioms justifying Dempster's rule for the combination of belief functions induced b... View full abstract»

  • Learnable and nonlearnable visual concepts

    Valiant's theory of the learnable is applied to visual concepts in digital pictures. Several visual concepts that are easily perceived by humans are shown to be learnable from positive examples. These concepts include a certain type of inaccurate copies of line drawings, identifying a subset of objects at specific locations, and pictures of lines in a fixed slope. Several characterizations of visu... View full abstract»

  • Motion estimation with more than two frames

    The development of a general motion estimation system based on using three or more frames is reported. The relevant portion of the sequence is treated as a whole, thus simplifying the process of estimating the motion parameters, and making possible the computation of the motion parameters in terms of the natural center of motion. A general description of this motion estimation method is presented,... View full abstract»

  • Threshold superposition in morphological image analysis systems

    It is shown that four composite morphological systems, namely morphological edge detection, peak/valley extraction, skeletonization, and shape-size distributions obey a weak linear superposition, called threshold-linear superposition. The output image signal or measurement from each system is shown to be the sum of outputs due to input binary images that result from thresholding the input gray-lev... View full abstract»

  • Stochastic analysis of stereo quantization error

    The probability density function of the range estimation error and the expected value of the range error magnitude are derived in terms of the various design parameters of a stereo imaging system. In addition, the relative range error is proposed as a better way of quantifying the range resolution of a stereo imaging system than the percent range error when the depths in the scene lie within a nar...

  • Direct analytical methods for solving Poisson equations in computer vision problems

    Direct analytical methods are discussed for solving Poisson equations of the general form Δu=f on a rectangular domain. Some embedding techniques that may be useful when boundary conditions (obtained from stereo and occluding boundary) are defined on arbitrary contours are described. The suggested algorithms are computationally efficient owing to the use of fast orthogonal ... View full abstract»

  • Partial shape recognition: a landmark-based approach

    Publication Year: 1990 , Page(s): 470 - 483
    Cited by:  Papers (29)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1188 KB)  

    A method of recognizing partially occluded objects is presented in which each object is represented by a set of landmarks. Given a scene consisting of partially occluded objects, a model object in the scene is hypothesized by matching the landmarks of the model with those in the scene. A measure of similarity between two landmarks is needed to perform this matching. A local shape measure, spherici... View full abstract»

  • Invariant image recognition by Zernike moments

    Publication Year: 1990 , Page(s): 489 - 497

    The problem of rotation-, scale-, and translation-invariant recognition of images is discussed. A set of rotation-invariant features are introduced. They are the magnitudes of a set of orthogonal complex moments of the image known as Zernike moments. Scale and translation invariance are obtained by first normalizing the image with respect to these parameters using its regular geometrical moments. ... View full abstract»

  • Correspondenceless stereo and motion: planar surfaces

    It is shown that a binocular observer can recover the depth and three-dimensional motion of a rigid planar patch without using any correspondences between the left and right image frames (static) or between the successive dynamic frames (dynamic). Uniqueness and robustness issues are studied with respect to this problem and experimental results are given from the application of the theory to real ... View full abstract»

    Two algorithms to find the longest common subcurve of two 2D curves are presented. These algorithms are based on conversion of the curves into shape signature strings and application of string matching techniques to find long matching substrings, followed by direct curve matching of the corresponding candidate subcurves to find the longest matching subcurve. The first algorithm is of complexity O(... View full abstract»
