A New Algorithm for Content-Based Region Query in Multimedia Databases

This article presents an original method of implementation of the color set back-projection algorithm. This is one of the most efficient methods of automated detection of color regions from an image. The detected regions are then used in the content-based region query. The query is realized on one or more regions, taking into consideration the color feature, location, area and the minimal bounding rectangle of the regions. The efficiency of the method was studied by means of a number of experiments effectuated with the help of a software system realized for this purpose, on a collection of synthetic images. This method of implementation influences the content-based region query efficiency in a series of domains in which this technique is used, such as medicine, art, education.
