Abstract
In one embodiment, a system may access a training sample from a training dataset, including a training image of a scene and a corresponding depth map. The system may access a circle-of-confusion map for the scene, which is generated based on the depth map and encodes a desired focal surface in the scene. The system may generate an output image by processing the training image, the corresponding depth map, and the corresponding circle-of-confusion map using a machine-learning model. The system may update the machine-learning model based on a comparison between the generated output image and a target image depicting the scene with a desired defocus-blur effect. The updated machine-learning model is configured to generate images with defocus-blur effect based on input images and corresponding depth maps.
