  • Finding point correspondences in motion sequences preserving affine structure 

    Banerjee, Subhashis; Sudhir, G; Zisserman, Andrew (1997)
    In this paper the problem of computing the point correspondences in a sequence of time-varying images of a 3D object undergoing nonrigid (affine) motion is addressed. It is assumed that the images are obtained through ...
  • Modeling of free-form surfaces and shape from shading 

    Sanyal, Subhajit; Bansal, Mayank; Banerjee, Subhashis; Kalra, Prem K (2004)
    Modeling a free-form 3D-surface from a single view has been a widely pursued problem. The existing schemes are either fully-automatic shape-from-X techniques or involve adept interaction from the user but little or no ...
  • Object tracking using affine structure for point correspondences 

    Singh Manku, Gurmeet; Jain, Pankaj; Aggarwal, Amit; Lalit Kumar; Banerjee, Subhashis (1997)
    A new object tracking algorithm based on affine structure has been developed and it is shown that its performance is better than that of a Kalman filter based correlation tracker. The algorithm is fast, reliable, viewpoint ...
  • Recognition of partially occluded objects using neural network based indexing 

    Rajpal, Navin; Chaudhury, Santanu; Banerjee, Subhashis (1999)
    In this paper, a new neural network based indexing scheme has been proposed for recognition of planar shapes. Local contour segment-based-invariants have been used for indexing. Object contours have been obtained using a ...
  • An uncalibrated lightfield acquisition system 

    Sharma, Puneet; Parashar, Angshuman; Banerjee, Subhashis; Kalra, Prem (2004)
    Acquisition of image data for lightfield usually requires an expensive, complex and bulky setup. In this paper, we describe a simple method of acquiring the image data set. The method requires a normal handheld video camera, ...
