Abstract

Humans and technology are two things that can not be separated. The rate of population growth, which is growing rapidly, proportional to the needs of people in many ways. Each activity and human needs, should be documented, so any activity and human needs can be predicted. Therefore, the data need to be collected and stored properly, effectively, and accuratel. Socio-Technical System is expected to assist and facilitate human in performing the collection and storage of data. Socio-Technical System can be applied by taking into account various aspects ranging from social, psychological, computer science, and technical. Methods of Socio-Technical implementation consists of requirements analysis, system design, implementation, testing, deployment, maintenance. In the testing phase, it should be noted the social and psychological aspects of the user.

Abstract

Along with the times, information retrieval is no longer just on textual data, but also the visual data. The technique was originally used is Text-Based Image Retrieval (TBIR), but the technique still has some shortcomings such as the relevance of the picture successfully retrieved, and the specific space required to store meta-data in the image. Seeing the shortage of Text-Based Image Retrieval techniques, then other techniques were developed, namely Image Retrieval based on content or commonly called Content Based Image Retrieval (CBIR). In this research, CBIR will be discussed based on color, shape and texture using a color histogram, Gabor and SIFT. This study aimed to compare the results of image retrieval with some of these techniques. The results obtained are by combining color, shape and texture features, the performance of the system can be improved.
