Image color filling method, device, equipment and storage medium

Abstract

The embodiment of the invention discloses an image color filling method, a device, equipment and a storage medium, and the method comprises the steps: in response to a color filling triggering operation acting on a target image, determining an initial current color filling block from an image block set corresponding to the target image; when it is detected that the read-back operation is not executed on the current color filling block, reading all pixel points in the current color filling block back to the cache block; performing color filling on the current color filling block based on each pixel point in the cache block corresponding to the current color filling block; and determining a next color filling block according to the color filling result of the current color filling block, taking the next color filling block as a new current color filling block, and returning to execute a read-back detection operation of the current color filling block until it is determined that the nextcolor filling block does not exist in the target image. By utilizing the method, the whole target image is prevented from being read back to the memory before color filling, the memory resource occupation in the color filling process is reduced, the dynamic optimization of the memory during image color filling is realized, the color filling time of image color filling is shortened, and the color filling efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to an image coloring method, device, device, and storage medium. Background technique [0002] With the popularization of smart devices and the improvement of image technology, smart devices also have the function of digital cameras. Users can activate the camera function of smart devices at any time in outdoor entertainment or daily life to take pictures instead of specific camera devices. To enhance the fun and playability of smart devices, smart devices also integrate some application software to support image processing, such as skin beautification, image stitching, image coloring, and graffiti. [0003] Generally, images for image processing are pre-stored in the memory of a graphics processor (Graphics Processing Unit, GPU), and when performing color-filling processing on images, image processing software cannot directly perform color-filling operations...

Problems solved by technology

[0004] In the process of implementing this application, the applicant found that the existing image coloring technology has the following defects: First, it takes a long time to transfer the pixel information of the entire image to the memory corresponding to the CPU, which affects the processing time of coloring. At the same time, if the image The size information is very large, and it takes up a lot of memory resources after reading back. If only a small range of images is filled in in the end, it will cause a waste of memory resources.
