Problems solved by technology

[0004] However, since operations such as convolution are directly performed on the high-resolution original image, and a high-resolution enhanced image is directly output, the complexity of the image enhancement process based on deep learning in related technologies is high.

Embodiment Construction

[0106] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0107] A high dynamic range (High-Dynamic Range, HDR) image can provide more dynamic range and image details than a low dynamic range (Low-Dynamic Range, LDR) image. According to the LDR images with different exposure times, the final HDR image can be synthesized by using the LDR images corresponding to the best details of each exposure time, and the synthesized HDR images can better reflect the...

Abstract

The present disclosure relates to an image enhancement method, device, electronic equipment, and storage medium. The method includes: acquiring a target image to be enhanced, and performing down-sampling processing on the target image to obtain a down-sampled image; Input the sampled image into the pre-trained deep learning network to obtain the image enhancement data corresponding to the downsampled image; determine the matching point of each pixel in the target image in the downsampled image; For each pixel in the image enhancement data, based on the enhancement data corresponding to the matching point of the pixel in the image enhancement data, the target enhancement parameter corresponding to the pixel is determined; for each pixel in the target image, based on the pixel The target enhancement parameter corresponding to the point, and adjust the pixel value of the pixel point to obtain the enhanced image corresponding to the target image. The present disclosure can reduce the complexity of image enhancement processing while maintaining the image enhancement effect obtained based on deep learning.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an image enhancement method, device, electronic equipment and storage medium. Background technique [0002] When personal consumer devices are used for image acquisition, it is usually impossible to directly capture high dynamic range images, and it is also difficult to obtain continuous multiple frames of images with different exposures for multi-exposure fusion to obtain high dynamic range images. At this time, the image enhancement technology based on single frame is particularly important. Among them, the enhancement of single frame image can only adjust the parameters such as image brightness and contrast through the current image information, and obtain a high dynamic range image enhancement similar to multi-exposure fusion. Effect. [0003] Currently commonly used single-frame image enhancement methods are: image enhancement methods based on deep lea...
