Title:
METHOD AND APPARATUS FOR DETECTING RESOLUTION OF IMAGE
Document Type and Number:
WIPO Patent Application WO/2019/173954
Kind Code:
A1
Abstract:
A method and apparatus for detecting the resolution of an image, used for solving the problems of a large workload and high algorithm complexity when the resolution of an image is detected. The method comprises: scaling a first image of a first size to obtain a second image of a second size, and determining a first metric value of the first image and a second metric value of the second image, wherein the first metric value is used to characterize the resolution of the first image, and the second metric value is used to characterize the resolution of the second image; then, performing an operation on the first metric value and second metric value to obtain an operation result, comparing the operation result to a first threshold, and determining whether the first image is a clear image according to the obtained comparison result.
