Title:
IMAGE LIGHTING METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/019618
Kind Code:
A1
Abstract:
The present application discloses an image lighting method and device, an electronic device, and a storage medium. The method comprises: determining a convolutional neural network corresponding to a lighting operation type of an initial image; acquiring local feature information and global feature information of the initial image via the convolutional neural network; acquiring fusion feature information of the initial image via the convolutional neural network on the basis of the local feature information and the global feature information; acquiring a maximum pooling result graph and a minimum pooling result graph via the convolutional neural network on the basis of a brightness component graph of the initial image; acquiring a bilateral grid matrix of the initial image on the basis of the fusion feature information, the maximum pooling result graph, and the minimum pooling result graph; and performing affine transformation on the initial image according to the bilateral grid matrix, so as to acquire a target image, wherein the target image is an image acquired after the initial image is lighted according to the lighting operation type.
