Image super-resolution for dynamic rearview mirror

Method for applying super-resolution to one or more images captured by a camera device of a subject vehicle, comprising:

• for multiple image frames over a period of time of a scene representing a field of view rearward of the subject vehicle:
• identifying a region of interest within the multiple image frames;
• detecting a degree of object motion among the multiple image frames;
• if the degree of object motion includes one of pitch, no motion, and a small magnitude of motion less than a motion threshold, applying image registration for recognizing at least one of objects and features within the input image frames;
• applying temporally-implemented super-resolution to enhance the resolution within the region of interest of the multiple image frames;
• and
• generating a resulting image based on the multiple image frames with the temporally-implemented super-resolution applied thereto.

Apparatus for applying super-resolution to one or more images captured by a vision-based imaging system of a subject vehicle, comprising:

• a rear-view camera device configured to capture a plurality of image frames of a scene representing a field of view rearward of the subject vehicle;
• and
• a processing device configured to:
• receive the plurality of image frames captured by the rear-view camera device,
• identify, within each image frame, an enlarged center region having diminished resolution related to detail per pixel,
• apply at least one of a de-noising filter and a sharpening filter to the enlarged center region within each image frame to enhance the resolution within the enlarged center region,
• for the plurality of image frames having the at least one of the de-noising filter and the sharpening filter applied thereto:
• apply temporally-implemented super-resolution to the image frames dependent upon a location within each of the image frames, said location comprising the identified region of interest,
• generate a resultant image based on the temporally-implemented super-resolution applied to the image frames, and
• a rearview mirror display device configured to display images captured by the rear-view camera device.
