| Abstract | Basically, the task of Content Based Image Retrieval (CBIR) is, given an image from an user, to find the most similar images among images in the database. It is not an easy task due to the fact that the definition of "similarity" is very different between human and computer. This difference is called "semantic gap". To filling this gap, many methods try to take into account the user feedback, i.e., running the system in cycle, at each loop to ask the feedback from users on the output, then using it to refine the searching procedure. However, focusing too much on user feedback may be harmful as it shadows the importance of feature design on this task, especially in earlier loops when less information from users are available. Many researchers investigate feature extraction for CBIR since years so it is natural to raise a question: "Is the feature design is at the top of its performance?". Recently, the study on Searching Images with MPEG-7 (& MPEG-7-like) Powered Localized dEscriptors (SIMPLE) has shown that the answer is "No". Convinced by this work but without ignoring its limitations, in this article, we aim to show that, by carefully fine-tuning a SIMPLE based system applying on deep analyses, the performance can still be improved significantly. At the end, using Gaussian distribution to detect interest regions and using Jensen-Shannon Divergence as the distance measure seems to be the key points to bootstrap the system performance. The significant relative Mean Average Precision improvements on UCID (5--7%) and UKBench (24--36%), the two well-known datasets for CBIR, support this conclusion. However, clustering the final results according to another similarity measure based on manual tags (textual features), we show that the semantic gap remains large. The integration of visual and textual features for CBIR is therefore necessary. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
