Abstract: A method and apparatus for converting a picture into a video, and a device and a storage medium. The method for converting a picture into a video includes: partitioning an original picture to obtain a foreground region and a background region; performing an iterative transformation for visual depth on the background region, and storing an image obtained through each transformation as a picture frame to obtain multiple frames of images; and splicing the multiple frames of images to obtain a target video. The iterative transformation includes at least two transformations for visual depth.

Abstract: An image generation system is described. The system comprises a neural network model configured to perform a diffusion process to generate a set of multi-view images from a same input prompt. The set of multi-view images have a same subject from different view orientation. The neural network model comprises a self-attention layer configured to relate pixels across the set of multi-view images.

Abstract: A method and network for refining pixels in an image are provided. The method includes determining principle directions of a pixel in the image and determining a normal direction of the pixel in the image. The method further includes segmenting regions in the image as one or more horizontal regions and one or more vertical regions based on the normal direction of the pixel and obtaining global normalization information for the image from the segmented regions. The method also includes refining the principle directions of the pixel in the image based on the global normalization information. A method is also provided for determining perspective directions of pixels in the image.

Abstract: Provided are image rendering methods and one or more apparatus, electronic devices, and storage media. One of the methods includes determining an image to be rendered, wherein a virtual object is newly added to the image to be rendered; determining local lighting information and global lighting information corresponding to the image to be rendered; and projecting and rendering the virtual object in the image to be rendered by combining the local lighting information with the global lighting information.
