Mutual information aspects of scale space images

In image registration mutual information is a well-performing measure based on principles of uncertainty. Similarly, in image analysis the Gaussian scale space, based on minimal assumptions of the image, is used to derive intrinsic properties of an image. In this paper a combination of both methods is investigated. This results in a parametrized mutual information measure using local informatio...

Multi-channel Mutual Information Using Scale Space

We propose a new voxel similarity measure which utilises local image structure as well intensity information. Gaussian scale space derivatives are used to provide the structural information. Each derivative is assigned to an information channel of higher dimensional form of normalised mutual information. We illustrate the behaviour of the measure for a simulated signal and 2D medical brain imag...

Scale-Space Mutual Information for Textural-Patterns Characterization

The essence of image texture is typically understood by two aspects. First, within a texture-pattern there is a significant variation in intensity values between nearby pixels. Second, texture is a homogenous property at some spatial scale larger than the spatial resolution of the image. Motivated by the essential aspects of image texture, this paper proposes a novel methodology that combines t...

Affine Registration with Feature Space Mutual Information

This paper introduces two important issues of image registration. At first we want to recall the very general definition of mutual information that allows the choice of various feature spaces to perform image registration. Second we discuss the problem of finding the global maximum in an arbitrary feature space. We used a very general parallel, distributed memory, genetic optimization which tur...

Web Scale Competitor Discovery Using Mutual Information

The web with its rapid expansion has become an excellent resource for gathering information and people’s opinion. A company owner wants to know who is the competitor, and a customer also wants to know which company provides similar product or service to what he/she is in want of. This paper proposes an approach based on mutual information, which focuses on mining competitors of the entity(such ...
