  • Segmentation of range images: an orthogonal moment-based integrated approach 
    Ghosal, Sugata (IEEE, 1993)
    A new approach to range image segmentation is presented. The proposed approach involves two phases in which the region and edge information detected using a set of orthogonal Zernike moment-based operators are combined to ...
  • Orthogonal moment operators for subpixel edge detection 
    Ghosal, Sugata (Elsevier, 1993-02)
    A new approach to detect step edges with subpixel accuracy is presented. The proposed approach is based on a set of orthogonal complex moments of the image known as Zernike moments. An ideal two-dimensional (2D) step edge ...
  • Detection of composite edges 
    Ghosal, Sugata (IEEE, 1994-01)
    The paper presents a new parametric model-based approach to high-precision composite edge detection using orthogonal Zernike moment-based operators. It deals with two types of composite edges: (a) generalized step and (b) ...
  • Forced axisymmetric response of linearly tapered circular plates 
    Goyal, Navneet (Elsevier, 1994-05)
    Forced axisymmetric response of a circular plate of linearly varying thickness, based on the classical theory, is analyzed by the eigen-function method. An exact solution for the free vibration mode shapes is obtained by ...
  • Forced Motion of a Semi-Infinite Plate of Linearly Varying Thickness 
    Goyal, Navneet (Elsevier, 1994-06)
    Forced motion of a semi-infinite plate of linearly varying thickness based on classical theory is analyzed by an eigenfunction method. Uniformly distributed and concentrated impulsive loads applied to plates clamped at ...
  • Effect Of Transverse Shear And Rotatory Inertia On The Forced Motion Of A Plate-Strip Of Linearly Varying Thickness 
    Goyal, Navneet (Elsevier, 1994-07)
    Shear theory and the eigenfunction method are used to analyze the forced motion of a plate-strip of linearly varying thickness. A plate clamped at both edges and a cantilever plate subjected to uniformly distributed and ...
  • Range surface characterization and segmentation using neural networks 
    Ghosal, Sugata (Elsevier, 1995)
    This paper presents an integrated neural net-based approach to the segmentation of range images into distinct surfaces, which is an essential step in range image analysis and interpretation. A two-stage connectionist neural ...
  • Target detection in foveal ATR systems 
    Ghosal, Sugata (IEEE, 1996)
    Automatic target recognition (ATR) applications require simultaneously a wide field of view (FOV) for better detection and situation awareness, high resolution for target recognition and threat assessment, and high frame ...
  • A fast scalable algorithm for discontinuous optical flow estimation 
    Ghosal, Sugata (IEEE, 1996-02)
    Multiple moving objects, partially occluded objects, or even a single object moving against the background gives rise to discontinuities in the optical flow field in corresponding image sequences. While uniform global ...
  • A moment-based unified approach to image feature detection 
    Ghosal, Sugata (IEEE, 1997-06)
    In this paper, a novel model-based approach is proposed for generating a set of image feature maps (or primal sketches). For each type of feature, a piecewise smooth parametric model is developed to characterize the local ...
  • Efficient algorithms for delay-bounded minimum cost path problem in communication networks 
    Narang, Nishit (IEEE, 1998)
    As the amount of data transmitted over a network increases and high bandwidth applications requiring point to multipoint communications like videoconferencing, distributed database management or cooperative work become ...
  • Efficient Algorithms for Delay-bounded Multicast Tree Generation for Multimedia Applications 
    Narang, Nishit (Springer, 1999)
    Given a network topology and costs associated with the links, the problem of generating a minimum cost multicast tree can be modelled as a Steiner tree problem. However, many real time applications such as video-conferencing ...
  • Forced asymmetric response of linearly tapered circular plates. 
    Goyal, Navneet (Elsevier, 1999-03)
    The eigenfunction method is used to analyze the asymmetric response of linearly tapered circular plates subjected to transverse loads, uniformly distributed over an annular sectorial area of the plate. The analysis is based ...
  • An image retrieval system with automatic query modification 
    Ghosal, Sugata (IEEE, 2002-06)
    Most interactive "query-by-example" based image retrieval systems utilize relevance feedback from the user for bridging the gap between the user's implied concept and the low-level image representation in the database. ...
  • Adaptable Similarity Search using Non-Relevant Information 
    Ghosal, Sugata (Elsevier, 2002-08)
    This chapter presents a novel technique for improving the accuracy of adaptable similarity based retrieval by incorporating negative relevance judgment, and demonstrates excellent performance and robustness of the proposed ...
  • Automatic substructuring for domain decomposition using neural networks 
    Ghosal, Sugata (IEEE, 2002-08)
    Application of neural networks for guiding solutions of large numerical problems is an emerging area of research. Automatic generation of subdomains from large 3D finite element meshes is a key preprocessing step in domain ...
  • Leveraging non-relevant images to enhance image retrieval performance 
    Ghosal, Sugata (ACM Digital Library, 2002-12)
    Inherent subjectivity in user's perception of an image has motivated the use of relevance feedback (RF) in the image desigined output's retrieval process. RF techniques interactively determine the user's query concept, ...
  • 3G Mobile Networks: Architecture, Protocols and Procedures 
    Narang, Nishit (McGraw Hill, 2004)
    In India, the mobile subscriber baser is increasing at a phenomenal rate. After the successful adoption of Second Generation (2G) Technology GSM and 2.5G Technology GPRS, the industry is now rapidly moving towards Third ...
