Among them, the interactive smart panel can be an integrated device that controls the content displayed on the display panel and realizes human-computer interaction through touch technology. One or more fun...

Embodiment 2

[0090] image 3 A schematic flowchart of an image coloring method provided in Embodiment 2 of the present application. This Embodiment 2 is optimized based on the above embodiments. In this embodiment, it is further determined from the set of image blocks corresponding to the target image. The initial current color-filling block is embodied as: analyzing the operation data of the color-filling trigger operation to obtain the operation type of the color-filling trigger operation; determining the corresponding selected pixels of the target image under the operation type; Determine the target image block to which the selected pixel point belongs in the image block set; and use the target image block as the initial current color-filling block.

[0091] At the same time, in this embodiment, the current color-filling block will be filled based on each pixel in the cache block. Specifically, it is preferable to use the selected starting pixel in the current color-filling block as the...

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...
