Abstract

The embodiment of the invention provides an image processing method and device, electronic equipment and a computer readable storage medium. The method comprises the steps of calculating amplificationfilling parameters; for each output position of the output image of the output layer, calculating a pixel value of a pixel point of the output position by adopting the following modes: obtaining a convolution kernel coverage range; Calculating an input image coverage range; determining an element corresponding to each pixel point in the coverage range of the input image in the input image; carrying out dot product operation on the input vector and the convolution kernel vector to obtain a pixel value of a pixel point at the output position; Wherein the input vector is a vector formed by pixelvalues of pixel points of the input image in a coverage range of the input image according to a preset sequence; wherein the convolution kernel vector is a vector which is composed of elements respectively corresponding to each pixel point in the coverage range of the input image in the input image according to the preset sequence. Image processing efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device, electronic equipment and computer-readable storage medium. Background technique [0002] When applying a convolutional neural network for image processing, it is often necessary to enlarge the feature map generated by the hidden layer to the size of the original image, that is, to use the feature map generated by the hidden layer as the input image, and perform a transpose convolution operation on it to obtain the enlarged output image. At present, the commonly used method is: first, rotate the convolution kernel of the transposed convolution by 180° to obtain the rotated convolution kernel; then enlarge the input image to the same width and height as the output image to obtain the enlarged input image Image, wherein the enlargement process is divided into two steps: the first step is internal filling and the second step is ed...
