Multi-resolution warping

An apparatus, comprising:

• a memory storing processor-readable code;
• and
• at least one processor coupled to the memory, the at least one processor being configured to:
• receive image data comprising one or more input image frames;
• receive a regions map indicating one or more regions in the image data, wherein the regions map associates each region with one of one or more image parameters;
• assign, based on the regions map, each coordinate of a subset of coordinates for an output image frame to one of the one or more regions;
• determine, for each coordinate of the subset of coordinates for the output image frame, one or more input pixels from a corresponding location in one of the one or more input image frames having an image parameter associated with a region assigned to the coordinate;
• and
• determine the output image frame by warping the one or more input pixels to align towards the subset of coordinates for the output image frame.

An image capture device, comprising:

• an image sensor configured to generate image data comprising at least two input image frames;
• a memory storing processor-readable code;
• and
• at least one processor coupled to the memory and to the image sensor, the at least one processor configured to:
• receive the image data comprising the at least two input image frames;
• receive a regions map indicating at least two regions in the image data, wherein the regions map associates each region with one of at least two different image parameters;
• determine, based on the image data, a set of coordinates for an output image frame;
• assign, based on the regions map, each coordinate of a set of coordinates for an output image frame to one of the at least two regions;
• determine, for each coordinate for the output image frame, one or more input pixels from a corresponding location in one of the at least two input image frames having an image parameter associated with a region assigned to the coordinate;
• and
• determine the output image frame by warping the one or more input pixels to align towards the set of coordinates for the output image frame and interpolating the one or more input pixels after warping the one or more input pixels.
