US Patent 12022182 Visual feature based video effects

Techniques for visual feature based video effects are described and are implementable to determine one or more visual features associated with an individual and generate a modified video feed based on the visual features. The described implementations enable automatic focus of a video feed to a particular focal region based on facial features of the individual. For instance, a visual feature such as pupillary distance or pupil size is determined from a video feed. A focal distance is calculated based on the visual feature, e.g., indicating a region that the individual is focused on. A modified video stream is then generated based on the focal distance, for instance to focus the video stream to a specific focal plane.
