Abstract

Embodiments of the present invention provide a training method, medium, apparatus, and computing device for an image cropping prediction model. The method includes: acquiring feature information of an original image and information of cropped samples; inputting the feature information into the image cropping prediction model; calculating according to the information of the predicted image output by the image cropping prediction model and the information of the cropped samples A loss function, which is used to train the image cropping prediction model. The image cropping prediction model trained by the embodiment of the present invention can be used in the image cropping process, so that the image cropping process takes less time and the amount of calculation is small, and the situation of incomplete cropping or image distortion is avoided as much as possible, and is suitable for various images of different content. Embodiments of the present invention further provide an image cropping method and apparatus.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image cropping, and more particularly, embodiments of the present invention relate to a training method, medium, apparatus and computing device for an image cropping prediction model. Background technique [0002] This section is intended to provide a background or context for the embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] The purpose of image cropping is to change the size of the original image so that the size and aspect ratio of the cropped image meet the actual needs. The principle of image cropping is to keep the key content of the original image as much as possible after cropping, and the overall aesthetics will not be greatly affected. [0004] A few image cropping techniques currently exist. For example, the Seam Carving algorithm is a typical cropping algorith...
