Architecture of Software-Hardware Complex for Searching Images in Database

The article discusses a method to increase the efficiency of solving the problem of finding images in a database. This method is based on the use of perceptual hashing of an image, three levels of data parallelization and image search procedures. To implement parallel data processing, the principle of symmetric horizontal data distribution and the capabilities of modern processors (SIMD registers and corresponding instructions) are used. The results of a computational experiment, confirming the effectiveness of the proposed method, are presented.
