Image processing method based on convolution algorithm and chip

Abstract

The present applicant discloses an image processing method based on a convolution algorithm and a chip using the same. The image processing method comprises: step A, using a fast Fourier transform and a fast Fourier inverse transform to control an image template and an image to be processed to obtain convolution result elements in a space domain in a form of multiplication in a frequency domain; and step B, in which if there is a convolution result element that satisfies a preset gray value condition, then a gray value of a pixel point corresponding to the convolution result element in the image to be processed is set as a preset target gray value. The complexity of the calculation time is reduced, the volume of data for processing pixel points is also decreased, and the real-time performance of image processing is ensured.
