• Calculating the 3D-Pose of Rigid-Objects Using Active Appearance Models 

    Mittrapiyanuruk, Pradit; DeSouza, Guilherme; Kak, Avinash C. (IEEE, 2004-05)
    This paper presents two different algorithms for object tracking and pose estimation. Both methods are based on an appearance model technique called Active Appearance Model (AAM). The key idea of the first method is to ...
  • Feature Extraction in Images 

    Harlow, Charles A.; Otto, Jacqueline L.; Hall, David L.; Lodwick, Gwilym S. (Gwilym Savage), 1917- (Institute of Electrical and Electronics Engineers, 1971-10)
    The problem considered is the extraction of features from a complicated set of images. In this approach the basic concepts used in the feature extraction process are: 1)an algorithm that enumerates regions; 2)a search for ...
  • GPU-Based Simulation of Cellular Neural Networks for Image Processing 

    Dolan, Ryanne; DeSouza, Guilherme (IEEE, 2009-06)
    The inherent massive parallelism of cellular neural networks makes them an ideal computational platform for kernelbased algorithms and image processing. General-purpose GPUs provide similar massive parallelism, but it can ...
  • Homography-Based Ground Plane Detection for Mobile Robot Navigation Using a Modified EM Algorithm 

    Conrad, Daniel, 1986-; DeSouza, Guilherme (IEEE, 2010-05)
    In this paper, a homography-based approach for determining the ground plane using image pairs is presented. Our approach is unique in that it uses a Modified Expectation Maximization algorithm to cluster pixels on images ...
