Generation of optical flow maps based on foreground and background image segmentation

At least one non-transitory computer readable medium comprising computer readable instructions to cause programmable circuitry to at least:

• generate a reference optical flow map based on a stereo pair of background images corresponding to a first camera field-of-view and a second camera field-of-view;
• generate a first optical flow map based on a stereo pair of input images corresponding to the first camera field-of-view and the second camera field-of-view;
• merge the reference optical flow map and the first optical flow map based on an alpha matte to generate a second optical flow map associated with the stereo pair of input images, the alpha matte representative of segmentation of at least one of the stereo pair of input images into foreground and background regions;
• and
• output the second optical flow map to at least one of a video processor or a video application.

A method to generate optical flow maps, the method comprising:

• generating, by executing an instruction with programmable circuitry, a reference optical flow map based on a stereo pair of background images corresponding to a first camera field-of-view and a second camera field-of-view;
• generating, by executing an instruction with the programmable circuitry, a first optical flow map based on a stereo pair of input images corresponding to the first camera field-of-view and the second camera field-of-view;
• combining, by executing an instruction with the programmable circuitry, the reference optical flow map and the first optical flow map based on an alpha matte to generate a second optical flow map associated with the stereo pair of input images, the alpha matte representative of segmentation of at least one of the stereo pair of input images into foreground and background regions;
• and
• outputting the second optical flow map to at least one of a video processor or a video application.
