Abstract

The invention discloses an image processing method and device, and a storage medium, and belongs to the technical field of electronics. The method comprises the following steps: obtaining a first bitmap; extracting a first image feature of the first bitmap through a feature extraction module of an inverse filtering processing model; performing convolution processing on the first image feature and a model parameter of an inverse filtering processing model through a convolution processing module of the inverse filtering processing model to obtain a second image feature; inputting the second image feature into a generation module of an inverse filtering processing model to obtain a second bitmap; and vectorizing the second bitmap to obtain a first vector diagram. The inverse filtering processing model is obtained by training bitmaps with different image contour definitions, the image features comprise at least one of a statistical feature in a frequency domain, a kurtosis coefficient feature and a color saturation feature, and the image contour definition of the second bitmap is greater than that of the first bitmap.

Description

technical field [0001] The present application belongs to the technical field of image processing, and specifically relates to an image processing method, device and storage medium. Background technique [0002] Bitmap and vector graphics are two concepts of modern computer plane graphics. Bitmap is composed of pixels, so the image may be distorted when enlarged or reduced. Vector graphics are calculated through mathematical formulas and have the feature of no distortion after editing. Therefore, in practical applications, such as map making, it is often necessary to convert bitmaps into vector graphics. [0003] However, the pixels at the edge of the bitmap are often blurred, so in the process of converting the bitmap into a vector image, there will be adhesion between words and words, words and lines, and lines and lines caused by the gray gradient of the edge of the word line problem, image fidelity cannot be guaranteed. Contents of the invention [0004] The purpose...
