An improved method of frequency domain processing for image deblurring system

Abstract

In engineering application, when dealing with fuzzy images,due to the way of space deconvolution is more difficult, the frequency domain transformation of the image is usually processed and implemented in the frequency domain.In the light of the frequency domain processing of image deblurring system has such problems as large consumption of hardware resources, poor flexibility of conversion and long processing time, etc. Based on the DE2 development board as the hardware platform, combined with the characteristics of fuzzy image and deblurring algorithm, this paper designs and implements a frequency domain processing method for image deblurring system by means of input data preprocessing, in situ calculation, throwing position, pipeline structure and parallel processing. The experimental data show that the accuracy of the method in the frequency domain processing of the image data is kept above 98%, and the hardware resources only use 9 162 logical units. The experimental results show that the system designed in this paper is superior to other similar systems in processing precision and resource utilization.
