An image reconstruction system based on cross array of memristors

Abstract

The invention discloses an image reconstruction system based on cross array of memristors, including an image input processing module, a sparse encode module and an image output processing module, wherein the sparse encoding module comprises a first memristor cross array, a calculation conversion unit and a second memristor crossover array. The system realizes the image pixel dictionary set through two memristors crossing arrays, and the sparse coding is performed based on the two memristor crossover arrays to realize image reconstruction. Because the memristor consumes very little power, theoverall power consumption of the system is reduced compared with the existing schemes. In addition, the memristor processes data quickly, and the size of the nano-memristor cross-array is small, whichis easy to integrate, and the important vectors in the sparse coding can be realized efficiently and conveniently, so that the coding speed is faster, the efficiency of the system is improved, but also a valuable reference direction is provided for large-scale hardware implementation.

Description

technical field [0001] The invention relates to the technical field of image processing, and more specifically, to an image reconstruction system based on a memristor cross array. Background technique [0002] Image reconstruction technology was initially applied in radiation medical equipment to display images of various parts of the human body, that is, computed tomography technology, or CT technology for short, and has gradually been applied in many fields. At present, the process of reconstructing images based on traditional hardware technical support is very energy-intensive and time-consuming. Therefore, how to realize image reconstruction under the premise of satisfying low power consumption has become a technical problem that needs to be solved urgently. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an image reconstruction system based on a memristor cross array, which implements image reconstructi...
