Abstract: The present application discloses an image quality evaluation method and apparatus, a device, and a storage medium. The method includes: acquiring a to-be-evaluated image; and inputting the to-be-evaluated image into an image quality evaluation network to obtain an image quality evaluation result, where the image quality evaluation network is configured to extract a first image feature from an input image, perform a shift operation on the first image feature to acquire one or more second image features, and determine the image quality evaluation result by combining the first image feature and the acquired second image features; a size of each of the second image features is the same as a size of the first image feature, and regions with identical values of features exist in different positions between the first image feature and the second image features.

Abstract: The supporting sheet assembly comprises several supporting sheets. Each supporting sheet includes a supporting sheet body and a nut installed on one side of the supporting sheet body. A protective layer is provided on the side of the supporting sheet body where the nut is installed. An opening is dug in the protective layer at the top part of the nut so as to expose the nut. Along the axis direction of the nut, the height of the protective layer is greater than the height of the nut, which reduces problems such as poor attachment and the generation of air bubbles caused by the difference in force between the position of the nut and the position without the nut on the supporting sheet.

Abstract: A video enhancement method and apparatus, an electronic device, and a storage medium are described. The method comprises: extracting features from M frames of images, so as to obtain at least one first-scale image feature (S310); for each first-scale image feature, performing N-level down-sampling processing on the first-scale image feature, so as to obtain a second-scale image feature (S320); performing N-level up-sampling processing on the second-scale image feature, so as to obtain a third-scale image feature (S330), wherein the input of ith-level up-sampling processing is an image feature obtained after performing superimposition processing on the output of (N+1−i)th-level down-sampling processing and the output of (i−1)th-level up-sampling processing, and the multiple of jth-level up-sampling is the same as the multiple of (N+1−j)th-level down-sampling; and performing superimposition processing on the third-scale image feature and the first-scale image feature.
