Context Dependent Colour Halftoning in Digital Printing
Halftoning of a colour image is normally performed by halftoning the colour separations independently. Each halftoned image then builds the corresponding colour separation of the ...

Perceptually Based Image Comparison
In this work a new perceptually based method of image comparison is proposed. It is based on the colour comparison in a perceptually uniform colour space CIE Luv, and using Contra...

A Sound Algorithm for Region-Based Image Retrieval Using an Index
Region-based image retrieval systems aim to improve the effectiveness of content-based search by decomposing each image into a set of “homogeneous” regions. Thus, similarity b...

Orthonormal Finite Ridgelet Transform for Image Compression
A finite implementation of the ridgelet transform is presented. The transform is invertible, non-redundant and achieved via fast algorithms. Furthermore we show that this transfor...

Multi-valued Images and Their Separation
Abstract. Consider scenes deteriorated by reflections off a semireflecting medium (e.g., a glass window) that lies between the observer and an object. We present two approaches to ...
