Implementation of Search Process for a Content-Based Image Retrieval Application on System on Chip

The amount of multimedia information on digital platforms has been increasing over the years. Social networks and the advancement of technology have been a determining factor for this event. Due to this fact, the organization, qualification and handling of this type of information has become indispensable, as well as assuring the user the quality of the service in content and execution time in the retrieval of information. This paper presents the implementation of the search process of a content-based image retrieval system, using metric spaces to perform the search and recovery of the image. The high level synthesis is used to development the IP block that will carry out the recovery process in the programmable logic. The experiments are performed on a PYNQ-Z1 board from $\mathbf{Xillinx}\bigcirc\!\!\!\!\!\!{\mathrm{c}}$ and on a CPU $\mathbf{Intel}\bigcirc\!\!\!\!\!\!{\mathrm{c}}$ Core i5 7th generation. The effectiveness of the implementation is supported by the results obtained.
