Problems solved by technology

[0002] With the development of Internet technology, online video services have become the focus of current research. However, due to the influence of the video recording environment, video images are often recorded with low video clarity due to light conditions. In order to improve the video recording effect, often Image processing with dark light enhancement technology to improve video recording effect
[0003] In the existing technology, the dark light enhancement method of Retinex theory is a widely used image enhancement method at present. This method decomposes the input image into the product of the light map and the material map, then brightens the light map, and finally enhances The final light map is multiplied by the material map to obtain the output image. However, since the accurate solution of the light map involves large-scale sparse matrix operations, the dark light enhancement technology based on the Retinex theory takes a lot of time and requires high real-time performance during video recording. Adopting the Retinex theory does not apply

Embodiment 1

[0027] figure 1 This is a flow chart of an image processing method provided in the first embodiment of the present invention. This embodiment can be applied to the situation of improving the definition of video images. The method can be executed by an image processing device, which can use hardware and / or software. It can generally be integrated in a smart terminal and includes the following steps:

[0028] Step 110: Extract an image frame in a video image as an initial light map.

[0029] Among them, when the image continuously changes more than 24 frames per second, according to the principle of persistence of vision, the human eye cannot distinguish the static picture of a single image, and it looks like a smooth and continuous visual effect. Such a continuous picture is called a video. In the embodiment of the present invention, an image frame can be understood as a certain frame of a video image, and the initial light map can be an image that needs dark light enhancement, and ...

Embodiment 2

[0039] figure 2 It is a flowchart of an image processing method provided in the second embodiment of the present invention, see figure 2 , The embodiment of the present invention embodies the foregoing image processing method, and the image processing method provided by the embodiment of the present invention includes:

[0040] Step 210: Extract image frames of video images, and convert the image frames into a preset format.

[0041] Among them, due to different video capture devices, the extracted image frame formats are different. The preset format can be understood as the format for enhancing the initial light map processing, which can be YUV format or RGB format, specifically the image format preset by the user .

[0042] Specifically, after the video image is captured, the image frames can be extracted sequentially, or the image frames can be acquired in real time during the capture of the video image for subsequent image processing. After the image frame of the video image i...

Embodiment 3

[0074] The image processing device provided by the embodiment of the present invention can execute the image processing method provided by any embodiment of the present invention, and has the corresponding functional modules and beneficial effects for the execution method. The device may be implemented by software and / or hardware, and specifically includes: an image acquisition module 310, a smoothing processing module 320, and a precision improvement module 330.

[0075] The image acquisition module 310 is used for extracting image frames in the video image as the initial light map.

[0076] The smoothing processing module 320 is configured to smoothly process the texture details of the initial light map.

[0077] The accuracy improvement module 330 is configured to improve the edge accuracy of the initial light map after smoothing processing as a target image.

[0078] In the embodiment of the present invention, by extracting the image frame in the video image as the initial light m...

Abstract

The invention discloses an image processing method, device and equipment and a storage medium. The method comprises the following steps: extracting an image frame in a video image as an initial illumination image; smoothing texture details of the initial illumination image; and improving the edge precision of the initial illumination image after smoothing processing to serve as a target image. According to the invention, an image frame in a video image is extracted as an initial illumination image; smoothing processing is performed on texture details of the initial illumination image; the image quality is improved, the edge precision is improved, the output target image is enabled to be smooth with excessive texture details, more contour information in the image is reserved, the display effect is improved, rapid processing of the enhanced image in dark light is realized, the time overhead of an image processing process is reduced, the real-time performance of video recording is improved, and the user experience degree is enhanced.

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular to an image processing method, device, device, and storage medium. Background technique [0002] With the development of Internet technology, online video services have become the focus of current research. However, due to the impact of the video recording environment, the definition of video images is often low due to the limitation of light conditions during recording. In order to improve the video recording effect, often Use dark light enhancement technology to process the image to improve the video recording effect. [0003] In the prior art, the dark light enhancement method of Retinex theory is currently a widely used image enhancement method. The method decomposes the input image into the product of the light map and the material map, then brightens the light map, and finally enhances The resulting light map is multiplied by the material map t...
