Title:
METHOD AND DEVICE FOR PROCESSING IMAGE
Document Type and Number:
WIPO Patent Application WO/2020/211573
Kind Code:
A1
Abstract:
The embodiments of the present disclosure disclose a method and a device for processing an image. An embodiment of the method comprises: acquiring a target object illumination image and a target virtual object image, the target object illumination image including an object image and a shadow image corresponding to the object image; inputting the target object illumination image into a pre-trained shadow extraction model, and obtaining a resulting shadow image comprising distance information; generating, on the basis of the resulting shadow image, illumination direction information corresponding to the target object illumination image; generating, on the basis of the illumination direction information, a virtual object illumination image corresponding to the target virtual object image; and fusing the virtual object illumination image and the target object illumination image, so as to add the virtual object illumination image to the target object illumination image, so as to obtain a resulting image. According to the embodiment, a virtual object image can be better fused into a target object illumination image, improving the authenticity of the resulting image, and thus facilitating the improvement of the display effect of the image.
