    After the most prominent signal in an infrared image of the sky is extracted, the question is whether the signal corresponds to an aircraft. We present a new approach that avoids metric similarity measures and the use of thresholds, and instead attempts to learn similarity measures like those used by humans. In the absence of sufficient real data, the approach allows one to specifically generate a... View full abstract»

    Automatic 3D model acquisition and 3D tracking of simple objects under motion using a single camera is often difficult due to the sparsity of information from which to establish the model. We developed an automatic scheme that first computes a simple Euclidean model of the object and then enriches this model using hyperpatches. These hyperpatches contain information on both the orientation and int... View full abstract»

  • Spatial size distributions: applications to shape and texture analysis

    This paper proposes new descriptors for binary and gray-scale images based on newly defined spatial size distributions (SSD). The main idea consists of combining a granulometric analysis of the image with a comparison between the geometric covariograms for binary images or the auto-correlation function for gray-scale images of the original image and its granulometric transformation; the usual gran...

    A computer vision system for person-independent recognition of hand postures against complex backgrounds is presented. The system is based on the elastic graph matching, which was extended to allow for combinations of different feature types at the graph nodes View full abstract»

    Shows how the local slant and tilt angles of regularly textured curved surfaces can be estimated directly, without the need for iterative numerical optimization. We work in the frequency domain and measure texture distortion using the affine distortion of the pattern of spectral peaks. The key theoretical contribution is to show that the directions of the eigenvectors of the affine distortion matr... View full abstract»

  • Coarse-to-fine dynamic programming

    We introduce an extension of dynamic programming, we call "coarse-to-fine dynamic programming" (CFDP), ideally suited to DP problems with large state space. CFDP uses dynamic programming to solve a sequence of coarse approximations which are lower bounds to the original DP problem. These approximations are developed by merging states in the original graph into "superstates" in a coarser graph whic... View full abstract»

    Models of visual attention provide a general approach to control the activities of active vision systems. We introduce a new model of attentional control that differs in important aspects from conventional ones. We divide the selection into two stages, which is more suitable for the system as well as explaining different phenomena found in natural visual attention, such as the dispute between earl...

  • Basic processes of Chinese character based on cubic B-spline wavelet transform

    A novel approach based on cubic B-spline wavelet transform is proposed to process Chinese character including character compression, type zooming-in, and typeface composition. The basic idea is that a Chinese character is described by its contours which are represented by cubic B-spline functions, and each contour is decomposed into the details or the control points (wavelet coefficients) at diffe...

    This paper presents the measurement of colored object reflectance, under different, general assumptions regarding the imaging conditions. We exploit the Gaussian scale-space paradigm for color images to define a framework for the robust measurement of object reflectance from color images. Object reflectance is derived from a physical reflectance model based on the Kubelka-Munk theory for colorant ... View full abstract»

  • Hidden Markov models with spectral features for 2D shape recognition

    We present a technique using Markov models with spectral features for recognizing 2D shapes. We analyze the properties of Fourier spectral features derived from closed contours of 2D shapes and use these features for 2D pattern recognition. We develop algorithms for reestimating parameters of hidden Markov models. To demonstrate the effectiveness of our models, we have tested our methods on two im... View full abstract»

    Computing the weighted average of the pixel values in a window is a basic module in many computer vision operators. The process is reformulated in a linear vector space and the role of the different subspaces is emphasized. Within this framework wellknown artifacts of the gradient-based edge detectors, such as large spurious responses can be explained quantitatively. It is also shown that template...

    We propose a general scheme of region competition (GSRC) for image segmentation based on scale space. First, we present a novel classification algorithm to cluster the image feature data according to the generally defined peaks under a certain scale and a scale space-based classification scheme to classify the pixels by grouping the resultant feature data clusters into several classes with a stand...
