Interactive Flag Identification Using Image Retrieval Techniques
We propose an interactive system for identifying flags in photos taken from natural scenes. The system is interactive in two respects. First, because segmentation can be a difficu...

Comparing Haar-Hilbert and Log-Gabor Based Iris Encoders on Bath Iris Image Database
This papers introduces a new family of iris encoders which use 2-dimensional Haar Wavelet Transform for noise attenuation, and Hilbert Transform to encode the iris texture. In orde...
