Abstract
We use region growing technique to segment the images. Based on the segmented region, we then select the size of the region to construct indexing keys. By using region growing technique on DCT image we reduce the number of region which is on the segmented regions only. Based on these regions, we then construct the indexing keys to match the images. Our technique will reduce the process time of constructing indexing keys. The indexing keys will then be constructed by calculating the regions distance. Our proposed of recursive region growing is not a new technique but its application on DCT images to build indexing keys is quite new and has not been presented by many other authors. © 2007 Taylor & Francis Group.
