Human face recognition is an important area in the field of biometrics. It has been an active area of research for several decades, but still remains a challenging problem because of the complexity of the human face. In this thesis we describe fully automatic solutions that can locate faces and then perform identification and verification. We present a solution for face localisation using eye l...

Image retrieval and indexing techniques are important for efficient management of visual database. Many techniques are generally developed based on the associated compression domain. In the fractal domain, a fractal code is a contractive affine mapping that represents a similarity relation between the range block and the domain block in an image. A new algorithm of IFS fractal code for image re...

ractal geometry provides a basis for modF eling the infinite detail found in nature. Fractal methods are quite popular in computer graphics for modeling natural phenomena such as mountains, clouds, and many kinds of plants. Linear fractal models such as the iterated function system (IFS), recurrent iterated function system (RIFS), and Lindenmeyer systern (L-system) concisely describe complex ob...
