Code for content based image retrieval
Region Based Image Retrieval (RBIR) is an extension of content-based image
retrieval techniques . Region-based image retrieval systems provide new query
types to search for objects embedded in anarbitrary environment. An RBIR system
automatically segments images into a variable number of regions, and uses a
segmentation algorithm to extract a set of features (like color, shapes and sketches)
for each region. A function determines the differences between the database image
and a set of reference regions. Unfortunately, the large evaluation costs of the
dissimilarity function are restricting region-based image retrieval to relatively small
databases . The most crucial part of this approach is the segmentation of the
regions.
