Title:
IMAGE ENHANCEMENT METHOD AND APPARATUS, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/102644
Kind Code:
A1
Abstract:
Disclosed by the present application are an image enhancement method and apparatus, a terminal device and a computer-readable storage medium. The image enhancement method comprises: obtaining an image to be processed; performing a wavelet transform operation on the image to obtain original feature information of the image, the original feature information comprising global contour feature information, horizontal detail feature information, vertical detail feature information, and contrast detail feature information; inputting the original feature information into a trained target network for processing to obtain corresponding reconstruction feature information, the reconstruction feature information comprising global contour reconstruction information, horizontal detail reconstruction information, vertical detail reconstruction information, and contrast detail reconstruction information; performing an inverse wavelet transform operation on the reconstruction feature information to obtain a reconstructed image; the resolution of the reconstructed image is higher than the resolution of the image to be processed. The embodiment of the present application can accurately obtain a clearly reconstructed image according to the image to be processed.
