    Abstract: In one implementation, a method of performing perspective correction is performed 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, a plurality of images of a scene from a respective plurality of perspectives. The method includes capturing, using the image sensor, a current image of the scene from a current perspective. The method includes obtaining a depth map of the current image of the scene. The method include transforming, using the one or more processors, the current image of the scene based on the depth map, a difference between the current perspective of the image sensor and a current perspective of a user, and at least one of the plurality of images of the scene from the respective plurality of perspectives. The method includes displaying, on the display, the transformed image.

    Abstract: In some implementations, a method includes: determining a complexity value for first image data associated with of a physical environment that corresponds to a first time period; determining an estimated composite setup time based on the complexity value for the first image data and virtual content for compositing with the first image data; in accordance with a determination that the estimated composite setup time exceeds the threshold time: forgoing rendering the virtual content from the perspective that corresponds to the camera pose of the device relative to the physical environment during the first time period; and compositing a previous render of the virtual content for a previous time period with the first image data to generate the graphical environment for the first time period.

    Abstract: In some implementations, a method of reducing latency associated with an image read-out operation is performed at a device including one or more processors, non-transitory memory, an image processing architecture, and an image capture device. The method includes: obtaining first image data corresponding to a physical environment; reading a first slice of the first image data into an input buffer; performing processing operations on the first slice of the first image data to obtain a first portion of second image data; reading a second slice of the first image data into the input buffer; performing the image processing operations on the second slice of the first image data to obtain a second portion of the second image data; and generating an image frame of the physical environment based at least in part on the first and second portions of the second image data.

    Abstract: The method includes: obtaining a first image of an environment from a first image sensor associated with first intrinsic parameters; performing a warping operation on the first image according to perspective offset values to generate a warped first image in order to account for perspective differences between the first image sensor and a user of the electronic device; determining an occlusion mask based on the warped first image that includes a plurality of holes; obtaining a second image of the environment from a second image sensor associated with second intrinsic parameters; normalizing the second image based on a difference between the first and second intrinsic parameters to produce a normalized second image; and filling a first set of one or more holes of the occlusion mask based on the normalized second image to produce a modified first image.
