Title:
IMAGE PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/065604
Kind Code:
A1
Abstract:
The present description provides an image processing method and apparatus. The image processing method comprises: obtaining an image to be processed; converting the image to be processed into a grayscale image, and performing wavelet transform on the grayscale image to obtain high-frequency information of the image to be processed; creating, on the basis of the high-frequency information, a high-frequency image corresponding to the image to be processed; and processing the high-frequency image according to a preset image information density calculation strategy, and determining, according to the processing result, an image information density corresponding to each image area in the image to be processed.
