| dc.description.abstract | In this thesis a novel approach to image classification is presented. The thesis explores the use of
color feature vectors and CBIR ? retrieval methods in combination with Genetic Programming to
achieve a classification system able to build classes based on training sets, and determine if an
image is a part of a specific class or not.
A test bench has been built, with methods for extracting color features, both segmented and
whole, from images. CBIR distance-algorithms have been implemented, and the algorithms used
are histogram Euclidian distance, histogram intersection distance and histogram quadratic
distance. The genetic program consists of a function set for adjusting weights which corresponds to
the extracted feature vectors. Fitness of the individual genomes is measured by using the CBIR
distance algorithms, seeking to minimize the distance between the individual images in the training
set. A classification routine is proposed, utilizing the feature vectors from the image in question,
and weights generated in the genetic program in order to determine if the image belongs to the
trained class.
A test?set of images is used to determine the accuracy of the method. The results shows that
it is possible to classify images using this method, but that it requires further exploration to make it
capable of good results. | |
