Sequential particle swarm optimization for visual tracking
Visual tracking usually involves an optimization process for estimating the motion of an object from measured images in a video sequence. In this paper, a new evolutionary approac...

Colour quantisation through dithering techniques
Most colour image printing and display devices do not have the capacity to deal with true-colours. To display the image anyway, they need to apply a quantisation method to reduce ...

An Improved Peak-to-Average Power Ratio Estimation Scheme for OFDM Systems
—To approximate the exact peaks of continuous-time orthogonal frequency division multiplexing (OFDM) signals, four times oversampling is usually employed for discrete-time OFDM s...

Generalized Image Models and Their Application as Statistical Models of Images
A generalized image model (GIM) is presented. Images are represented as sets of four-dimensional (4D) sites combining position and intensity information, as well as their associat...
