Fractal code is a code from image encoding
process using Partitioned Iterated Function System (PIFS)
method. The characteristic of PIFS is self-similarity
searching between image parts based on pixel intensities
value. Thus it can be assumed that similarity of fractal code
represents similarity of pixel intensities variance pattern
which represents the image texture.
In this paper, fractal code based image retrieval system
called SPECKTRAL is proposed. Fractal code in this system
consists of two components that invariant to translation,
scale and rotation, i.e. contrast and brightness coefficients.
Fractal code similarity between two images measured with
the mean value of minimum Euclidean distance between
each contrast and brightness coefficients. If average distance
smaller, then the image considered has more similar texture.
The experiment results on Brodatz and Vistex image
collections show that system can retrieve most images that
have relevant texture to the query in early retrieval process
i.e. when 25% of images in the collection retrieved and
performs better for textural image collection.
