The use of information and information gain in the analysis of attribute dependencies

Krzysztof Moliński, Anita Dobek, Kamila Tomaszyk (2012)

Biometrical Letters

Similarity:

This paper demonstrates the possible conclusions which can be drawn from an analysis of entropy and information. Because of its universality, entropy can be widely used in different subjects, especially in biomedicine. Based on simulated data the similarities and differences between the grouping of attributes and testing of their independencies are shown. It follows that a complete exploration of data sets requires both of these elements. A new concept introduced in this paper is that...

Local correlation and entropy maps as tools for detecting defects in industrial images

Ewa Skubalska-Rafajłowicz (2008)

International Journal of Applied Mathematics and Computer Science

Similarity:

The aim of this paper is to propose two methods of detecting defects in industrial products by an analysis of gray level images with low contrast between the defects and their background. An additional difficulty is the high nonuniformity of the background in different parts of the same image. The first method is based on correlating subimages with a nondefective reference subimage and searching for pixels with low correlation. To speed up calculations, correlations are replaced by a...
