2. The objective of this research is to validate the feasibility of successful content based image
search using fractals. Fractal based approach has been embedded into one of the theories
of visual perception of an image. An important function of selective visual attention is to
direct our gaze rapidly towards objects of interest in our visual environment. Two distinct
pathways in human visual perception for scene recognition are what pathway and where
pathway. They work simultaneously to perceive scene as a whole. The proposed approach
simulates human visual perception mechanism similar to that of the brain. The Hausdorff
Fractals have been used in what pathway and Presence Score has been used in where
pathway to generate a composite feature vector. The feature vector captures color, shape,
texture information and significant region of interest of the image through fractals and
presence score. In order to improve retrieval performance in the sense of accuracy and
time, similar images are clustered together through maxdistnace and maxclustersize based
clustering approach. The results obtained with an optimum sized feature vector are good
enough to validate the approach and the conceptualized analogy between human and
computer based image processing. The search has also been successfully extended using
text annotation to web search through Google to provide wider coverage of CBIR.
