  • Speeding up Dense Disparity Estimation of Stereo Couples Thanks to Horizontal Intensity Gradient

    Cited by:  Patents (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2319 KB) | HTML iconHTML

    This paper presents an original development of disparity estimation from stereo couples primarily based on the similarity of image gradient between both images. Each pixel of the left image is associated to right image pixels with same gradient and similar intensity, directly leading to a set of disparities equal to the horizontal displacement in the specific case of epipolar images. Disparity val... View full abstract»

    The egomotion estimation problem is basic task to most of vision-based mobile robot applications. Recent research has shown that the use of omnidirectional systems with large field of view facilitates the computation of the observer motion. All previous work takes a motion field, computed in the image, as an input in egomotion estimation process. This motion field is calculated using classical alg... View full abstract»

    Dupin cyclides are non-spherical algebraic surfaces of degree 4, discovered by the French mathematician Pierre-Charles Dupin at the beginning of the 19th century. A Dupin cyclide has a parametric equation and two implicit equations and circular lines of curvature. It can be defined as the image of a torus, a cone of revolution or a cylinder of revolution by an inversion. A torus has two families o... View full abstract»

  • An Evolutionary-Based 3D Reconstruction Using an Uncalibrated Stereovision System

    Publication Year: 2009, Page(s):22 - 27
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (458 KB) | HTML iconHTML

    In this paper, we offer an original method for 3D shape reconstruction based on an uncalibrated stereovision system (USS). The USS is composed of five cameras located on an arc around the object to be analysed. The method operates in two steps. First, points of interest are detected in pairs of images acquired by two consecutive cameras of the USS and matched. Then, using evolutionary algorithms, ... View full abstract»

    Different facial expressions are related to a small set of muscles and limited ranges of motions. In this paper we propose an automatic facial expression recognition system, different from other automatic methods in both face detection and feature extraction. In system the facial expressions identify itself in video sequences. First, the differences between neutral and emotional states are detecte... View full abstract»

    This paper presents the implementation of moment invariants; with respect to centroid point obtained from frontal mugshot images, for thermal-based face identification system. Initially, seeded region growing method is applied for background filtering. Sequentially, the system decomposes a background filtered thermal image into 4 thermal regions via 3-valued threshold method. Region with the lowes... View full abstract»

  • A Novel Evolutionary Face Recognition Algorithm Using Particle Swarm Optimization

    Publication Year: 2009, Page(s):42 - 47
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (494 KB) | HTML iconHTML

    In this paper a novel algorithm to solve the problem of automatic face recognition is presented. The novelty of the algorithm is the ability to combine the computer vision tasks with Particle Swarm Optimization (PSO) to improve the execution time and to obtain better recognition results. The crucial stage of a typical system of face recognition is improved by using a fitness function to measure th... View full abstract»

    In this paper, an efficient local appearance feature extraction method based the multi-resolution Steerable Pyramids (SP) transform is proposed in order to further enhance the performance of the well known Fisher Linear Discriminant (FLD) method when applied to face recognition. Each face is described by a subset of band filtered images containing block-based SP coefficients. These coefficients ch... View full abstract»

    This work presents a digital imaging system able to assist physicians to track cervical cancer. The goal is to automatically extract the region where the cervical cancer starts to occur. This region called Acetowite Epithelium Zone (AEZ) is highlighted by physicians using a diluate acetic acid on the surface of the cervix. Recent digital images processing works suggested to extract this region wit... View full abstract»
