A novel photometric motion approach 16

16th brazilian symposium on computer graphics and image processing

作者： Torreao, JRA Fernandes, JL Leitao, HCG Pontificia Univ Catolica Parana Posgrad Informat Aplicada BR-80215901 Curitiba Parana Brazil

Photometric motion is a computer vision process for the estimation of shape from image sequences of dynamic scenes. It was introduced by Pentland, based on his observation that the photometric effects of motion - the intensity change of a moving point - could dominate the purely geometric ones, due to projective distortion. Here we present a novel formulation for the same shape estimation problem, whose distinctive feature is that of being based on the irradiance change, due to the motion, at a given point in the image plane, and not, as in the original proposal, at a fixed location on the moving surface. thus we obtain an easily implementable procedure which yields good-quality estimates, and which can be extended to single-input shape reconstruction.

ISBN: (纸本)0769520324

A robust and efficient technique to segment shaded areas in aerial color images is presented in this paper. this technique is based on the physical phenomenon of atmospheric dispersion of the sunlight most well known as the Rayleigh scattering effect. this technique does not depend on special algorithms to classify or to form clusters of objects appearing in complex aerial images. In fact, the mathematical model, derived from the physical model is very simple but it produces consistent results and can be applied to color images obtained by airborne and orbital sensors (e.g., Landsat TM and IKONOS).

Multiscale image segmentation using wavelets and watersheds 16

16th brazilian symposium on computer graphics and image processing

作者： Jung, CR Univ Vale Rio Dos Sinos Ctr Ciencias Exatas & Tecnol UNISINOS BR-93022000 Sao Leopoldo RS Brazil

ISBN: (纸本)0769520324

this paper proposes a new multiscale segmentation technique based on wavelet decompositions and watersheds. the wavelet transform is applied to the image, producing detail and approximation coefficients. the watershed is applied to the approximation image at a certain resolution 2(J), and projected up to higher resolutions using the inverse wavelet transform. At lower resolutions, the segmentation captures large relevant objects, while at higher resolution more details are obtained Since downsizing is inherent to the wavelet transform, watershed segmentation is applied to a smaller image, demanding less computational time. the proposed technique appears to be robust for noisy images, even when the amount of noise is very large.

A computer vision framework for eye gaze tracking 16

Eye gaze tracking (EGT) allow us to estimate the direction of gaze and the point of regard. this technique has been successfully used as pointing device in computer interfaces for people with disabilities, but significant technological advances are still required to make EGT appropriate to be used in general computer interfaces. In order to improve the EGT technology, a testbed where new devices and algorithms can be evaluated must be defined. this paper presents a survey of the methods used for EGT and organize them into a computer vision framework, that we use to support the development and evaluation of new techniques. As an example of application of the framework, the calibration function used in the EGT developed in our laboratory is tested, and the results show the precision of the method. Higher accuracy of the testing results is achieved using synthetic images generated by ray tracing, from a physically based model of the eye.

this article presents the language LinF for L-System specification. L-Systems are formal string rewriting systems introduced in 1968 by the botanist Aristid Lindenmayer that are used to model fractal images. LinF allows the definition of three-dimensional fractals and stochastic fractals. Together with the LinF definition this paper presents the implementation of cFLC, an OpenGL-based system that generates fractal images from LinF specifications. Results obtained through the LinF formalism show the ease of use and generality of the developed tools with respect to the existing literature.

ISBN: (纸本)0769520324

We present a system for collaborative conceptual design that allows users potentially located in geographically distant areas to cooperate by sketching, exploring and modifying their ideas interactively, with immediate visual feedback. the system supports several modeling primitives and can be easily extended with user-defined objects. In this context, we introduce the notions of animated and sketchy billboards. Applications of this system include early stages of urban and landscape design, rapid prototype of virtual environments, animation, education and recreational use.

this paper proposes an algorithm of image retrieval from a partial request. In order to retrieve images containing a specific object or group of objects, we use an algorithm of inexact graph matching, adapted to adjacency graphs of regions. the number of regions representing the object can be different from an image to the other. the algorithm uses a search tree in which only similar nodes are developed the adjacency and spatial relationship of regions are used to prune the tree and accelerate the retrieval. the algorithm computes a distance between graphs, allowing to rank images. this distance takes into account both the distance between region features and the relative position of regions.

Design of order statistic filters from examples 16

Order statistic filters form a subclass of the stack filters. the design of stack filters is computationally prohibitive for relatively large windows. A possible approach to overcome this difficulty is to constrain design to a smaller class. We propose an algorithm for the design of optimal order statistic filters from training data, and show how it can also be applied to the design of optimal weighted order statistic filters. Some examples that illustrate application of the proposed algorithm are presented, with considerations on training time and precision of the designed filter.

ISBN: (纸本)0769520324

this paper deals with content-based image indexing and category retrieval in general databases. When large categories are searched, systems must explore the database. We introduce an interactive retrieval strategy designed for database exploration. the technique is based on a compound query and a dedicated similarity function. the usual strategy based on a similarity score ranking is replaced by a stochastic image selection process. A competition between feature spaces for the similarity measure refinement is also included in the strategy. A quality assessment is realized on a general database of 6.000 images in order to illustrate and validate our approach.

the classical Douglas-Peucker line-simplification algorithm is recognized as the one that delivers the best perceptual representations of the original lines. It is used extensively for both computer graphics and geographic information systems. there are two variants of this algorithm, the original O(nm) method, where n denotes the number of input vertices and m the number of output segments, that works in any dimension, and the O(n log n) one, which only works for simple 2D planar polylines. In the both variants, a self-intersecting simplified line may be yielded if the accepted approximation is not sufficiently fine. Based on star-shaped subsets, we present in this paper yet another O(mn) Variant of Douglas-Peucker algorithm which preserves the non-self-intersection property for any predefined tolerance.
