  • Geodesic saliency of watershed contours and hierarchical segmentation

    The watershed is one of the latest segmentation tools developed in mathematical morphology. In order to prevent its oversegmentation, the notion of dynamics of a minimum, based on geodesic reconstruction, has been proposed. In this paper, we extend the notion of dynamics to the contour arcs. This notion acts as a measure of the saliency of the contour. Contrary to the dynamics of minima, our conce...

  • Elastic-model driven analysis of several views of a deformable cylindrical object

    This paper proposes a method to extract regions of a deformable object from several views of it while finding the correspondence of the object among the views. The method has been developed to analyze X-ray images of a stomach. Owing to the physical (not physiological) deformation of the stomach and changes of the camera angle, the shape of the stomach regions are fairly different among the images... View full abstract»

  • A transform for multiscale image segmentation by integrated edge and region detection

    Describes a transform to extract image regions at all geometric and photometric scales. It is argued that linear approaches have the shortcoming that they require a priori models of region shape. The proposed transform avoids this by letting the structure emerge, bottom-up, from interactions among pixels. The transform involves global computations on pairs of pixels followed by vector integration ... View full abstract»

  • Automatic feature generation for handwritten digit recognition

    An automatic feature generation method for handwritten digit recognition is described. Two different evaluation measures, orthogonality and information, are used to guide the search for features. The features are used in a backpropagation trained neural network. Classification rates compare favorably with results published in a survey of high-performance handwritten digit recognition systems.

  • Motion estimation with quadtree splines

    This paper presents a motion estimation algorithm based on a new multiresolution representation, the quadtree spline. This representation describes the motion field as a collection of smoothly connected patches of varying size, where the patch size is automatically adapted to the complexity of the underlying motion. The topology of the patches is determined by a quadtree data structure, and both s... View full abstract»

  • Incorporating language syntax in visual text recognition with a statistical model

    The use of a statistical language model to improve the performance of an algorithm for recognizing digital images of handwritten or machine-printed text is discussed. A word recognition algorithm first determines a set of words (called a neighborhood) from a lexicon that are visually similar to each input word image. Syntactic classifications for the words and the transition probabilities between ... View full abstract»

  • Rigidity checking of 3D point correspondences under perspective projection

    Cited by:  Papers (16)

    An algorithm is described which rapidly verifies the potential rigidity of three-dimensional point correspondences from a pair of two-dimensional views under perspective projection. The output of the algorithm is a simple yes or no answer to the question “Could these corresponding points from two views be the projection of a rigid configuration?” Potential applications include 3D objec...

  • Task-specific gesture analysis in real-time using interpolated views

    Hand and face gestures are modeled using an appearance-based approach in which patterns are represented as a vector of similarity scores to a set of view models defined in space and time. These view models are learned from examples using unsupervised clustering techniques. A supervised teaming paradigm is then used to interpolate view scores into a task-dependent coordinate system appropriate for ... View full abstract»

  • Real-time focus range sensor

    Structures of dynamic scenes can only be recovered using a real-time range sensor. Depth from defocus offers an effective solution to fast and dense range estimation. However, accurate depth estimation requires theoretical and practical solutions to a variety of problems including recovery of textureless surfaces, precise blur estimation, and magnification variations caused by defocusing. Both tex... View full abstract»

  • Multiple constraints to compute optical flow

    The computation of the optical flow field from an image sequence requires the definition of constraints on the temporal change of image features. In this paper, we consider the implications of using multiple constraints in the computational schema. In the first step, it is shown that differential constraints correspond to an implicit feature tracking. Therefore, the best results (either in terms o... View full abstract»
