ANSIG - An analytic signature for permutation-invariant two-dimensional shape representation
Many applications require a computer representation of 2D shape, usually described by a set of 2D points. The challenge of this representation is that it must not only capture the...

A Cross-Resolution Leaky Prediction Scheme for In-Band Wavelet Video Coding with Spatial Scalability
—In most existing in-band wavelet video coding schemes, over-complete wavelet transform is used for the motion-compensated temporal filtering (MCTF) of each spatial subband. It ...

Multiview image compression using a layer-based representation
We propose a novel compression method for multiview still images. The algorithm exploits the layer-based representation, which partitions the data set into planar layers character...

A Novel Method to Extract Features for Iris Recognition System
In general, the iris recognition systems have used the wavelet transform as feature extraction techniques. Since the wavelet transform does not have the shift-invariant property, t...
