Image processing method, device and equipment and readable storage medium

Abstract

The invention discloses an image processing method which comprises the steps of acquiring image input features of an association layer, acquiring a first weight parameter and a second weight parameterfrom an external memory at the same time, wherein the first weight parameter corresponds to the association layer, and the second weight parameter corresponds to an independent layer; calculating a first output feature by using the image input feature and the first weight parameter; calculating a second output feature corresponding to the first output feature by using the first output feature andthe second weight parameter, and storing the second output feature in an external memory. According to the method, a multi-layer continuous calculation mode is adopted, and a plurality of network layers are calculated for each channel during each calculation, so that the data exchange times of an internal memory and an external memory can be reduced, the data transmission time consumption is reduced, and the image processing speed is further improved. In addition, the invention also provides an image processing device, image processing equipment and a computer readable storage medium, which also have the above beneficial effects.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, an image processing device, an image processing device, and a computer-readable storage medium. Background technique [0002] The emergence of digital signal processors (DSP) helps to solve the problem of slow inference speed of neural network models in embedded devices. A digital signal processor is a processor composed of a large-scale or very large-scale integrated circuit chip used to complete a certain signal processing task. It adopts a Harvard structure in which programs and data are separated. This design allows pre-reading when executing current instructions. The next instruction, so it has a higher execution efficiency when performing image processing. [0003] However, the internal storage space of the digital signal processor is usually very small (for example, only 116KB). When the image input features and weights of the ...
