Video noise reduction for video augmented reality system

A system comprising a computing device, the computing device comprising:

• at least one processing device;
• and
• at least one computer readable data storage device storing instructions that, when executed by the at least one processing device, are operative to:
• receive an image from a camera;
• when a current frame matches one or more previous frames, track a user's eye to determine a location of where the user's eye is looking in a current frame of the image;
• determine a first region in the current frame of the image based on the location where the user's eye is looking in the current frame of the image, wherein the first region is a focus for noise reduction;
• determine a second region in one or more previous frames of the image, wherein the second region corresponds to the first region in the current frame of the image;
• align the second region in the one or more previous frames of the image with the first region in the current frame of the image to compensate for a motion between the first region and the second region;
• reduce noise of the first region based on an average according to the alignment of the second region to the first region;
• and
• display the first region in the current frame of display based on the noise reduction in the first region in the current frame of the image from the camera.

A method comprising:

• receiving a current frame of an image from a camera;
• retrieving from a store one or more previous frames of the image captured by the camera;
• when a current frame matches one or more previous frames, tracking a user's eye to determine a location of where the user's eye is looking in the current frame of the image;
• determining a first region in the current frame the image based on the location where the user's eye is looking in the current frame of the image, wherein the first region is a focus for noise reduction;
• determining a second region in the one or more previous frames of the image, wherein the second region corresponds to the first region in the current frame of the image;
• aligning the second region from the one or more previous frames of the image with the first region in the current frame of the image to compensate for a motion between the first region and the second region;
• reducing noise of the first region based on an average according to the alignment of the second region to the first region;
• and
• displaying the first region in the current frame of the image based on the noise reduction of the first region.
