    A machine is designed, based on a pyramid architecture, that supports smart sensing and related highly efficient processing. Key elements of the design are (a) hierarchical data structures for image representation, (b) fine-to-coarse algorithms for the fast generation of image measures, (c) coarse-to-fine search strategies that rapidly locate objects or events within a scene, and (d) high-level co...

    It is shown that electromagnetic field equations in rotating coordinates, obtained by several authors, are faulty due to their basis in incorrect expressions for the divergence and curl operators and the three-dimensional spatial vectors. A four-dimensional (4-vector) tensor formulation is used to show that Maxwell's equations are shown to be valid in rotating coordinates View full abstract»

    Perceptual processes responsible for computing shape from several cues, including shading, texture, contour, and stereo, are examined. It is noted that these computational problems, as well as that of computing shaping from motion, are ill-posed in the sense of Hadamard. It is suggested that regularization theory can be used along with a priori knowledge to restrict the space of possible solutions... View full abstract»

    A review of image-processing systems developed until now is given, highlighting the weak points of such systems and the trends that have dictated their evolution through the years producing different generations of machines. Each generation may be characterized by the hardware architecture, the programmability features and the relative application areas. The need for multiprocessing hierarchical s... View full abstract»

    The author provides a general introduction to computer vision. He discusses basic techniques and computer implementations, and also indicates areas in which further research is needed. He focuses on two-dimensional object recognition, i.e. recognition of an object whose spatial orientation, relative to the viewing direction is known View full abstract»

    Cited by:  Papers (192)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1884 KB)

    Mathematical results on ill-posed and ill-conditioned problems are reviewed and the formal aspects of regularization theory in the linear case are introduced. Specific topics in early vision and their regularization are then analyzed rigorously, characterizing existence, uniqueness, and stability of solutions. A fundamental difficulty that arises in almost every vision problem is scale, that is, t... View full abstract»

    Issues and techniques are discussed to automatically compile object and sensor models into a visual recognition strategy for recognizing and locating an object in three-dimensional space from visual data. Automatic generation of recognition programs by compilation, in an attempt to automate this process, is described. An object model describes geometric and photometric properties of an object to b...

    Options are examined that drive the design of a vision-oriented computer, beginning with the analysis of the basic vision computation and communication requirements. The classical taxonomy is briefly reviewed for parallel computers, based on the instruction and data stream. A recently proposed criterion, the degree of autonomy of each processor, is applied to further classify fine-grain SIMD (sing... View full abstract»

    Geometric matching algorithms and geometric representations are examined for point sets, curves, surfaces, volumes, and their space-time trajectories. The author focuses mainly on general-purpose techniques. Geometric matching benefits greatly from taking advantage of symmetries and special features, e.g. dihedral edges and circles or any three reliably identifiable feature points. Volume matching...

    Active perception (active vision specifically) is defined as a study of modeling and control strategies for perception. Local methods are distinguished from global models by their extent of application in space and time. The local models represent procedures and parameters such as optical distortions of the lens, focal lens, spatial resolution, bandpass filter, etc, The global models, on the other...

  • A novel interpretation of Prony's method

    The two key steps in Prony's method are interpreted as two key approximation problems. In the first, a nonhomogeneous, constant coefficient, linear difference equation is fitted to the samples. This difference equation is fitted so that the nonhomogeneous part of the difference equation is minimized in the least-squares sense. For the second problem, a homogeneous solution to the difference equati... View full abstract»

    Recent developments are reviewed in the computation of motion and structure of objects in a scene from a sequence of images. Two distinct paradigms are highlighted: (i) the feature-based approach and (ii) the optical-flow-based approach. The comparative merits/demerits of these approaches are discussed. The current status of research in these areas is reviewed and future research directions are in... View full abstract»
