We present a system for interactive animation of trees in a wind-field. Wind forces are simulated by Navier-Stokes equations, solved in real-time using multi-processor CUDA architecture. The dynamics of the tree is al...

In this paper, we study the face verification task across age by constructing a simple but powerful representation of the face which uses Local Binary Pattern (LBP) histograms. The spatial information is incorporated ...

In this paper, combinations of spatial orientation tree (SOT), two-dimensional complex wavelet transform (CWT) and vocabulary tree (VT) is used for feature collection and retrieval of the images from natural as well a...

Active appearance models (AAM), a group of flexible de-formable models, have been widely used in various applications such as, object tracking, medical image segmentation and synthesis. AAMs are statistical models whi...

This paper proposes a technique to develop a non-intrusive interface for human-computer interaction based on visual cues of a human eye, captured using a low resolution USB camera. Such an interface can replace a trad...

In this paper, we propose a real-time distributed framework for composite event recognition in a calibrated pan-tilt camera network. A composite event comprises of events that occur simultaneously or sequentially at d...

Recognizing a person's motion is intuitive for humans but represents a challenging problem in machine vision. In this paper, we present a multi-disciplinary framework for recognizing human actions. We develop a no...

Human eye fixation points occurring during the early stages of visual processing often correspond to the loci of salient image regions. These salient regions provide us with assistance in determining the interesting p...

In this paper, we present a novel scheme for segmenting video data into scenes. Based on visual similarity, the shots are first classified into clusters using modified k-means algorithm. Number of optimal clusters is ...
