Efficient Access Methods for Content-Based Image Retrieval with Inverted Files
Overview As human factor studies over the last thirty years have shown, response time is a very important factor for the usability of an interactive system, especially on the World Wide Web. In particular, response times of under one second are often specified as a usability requirement. This paper compares several methods for improving the evaluation time in a content-based image retrieval system (CBIRS), which uses inverted file technology. The use of the inverted file technology facilitates search pruning in a variety of ways, as is shown in this paper. Other search pruning methods, similar to methods used in information retrieval, can also reduce the response time significantly without reducing the performance of the system. The performance of the system is evaluated using precision vs. recall graphs, which are an established evaluation method in information retrieval.
