Abstract
In one implementation, a method of performing perspective correction is performed at a head-mounted device including at a head-mounted device including one or more processors, non-transitory memory, an image sensor, and a display. The method includes capturing, using the image sensor, an image of a scene. The method includes obtaining a plurality of depths respectively associated with a plurality of pixels of the image of the scene. The method includes generating a smooth depth map of the image of the scene based on the plurality of depths, wherein a difference between any two adjacent elements of the depth map is below a threshold. The method includes transforming, using the one or more processors, the image of the scene based on the smooth depth map and a difference between a perspective of the image sensor and a perspective of a user. The method includes displaying, on the display, the transformed image.
