Flicker suppression without motion estimation for single-image super-resolution

An electronic device comprising:

• at least one processing device configured to:
• obtain a first image and a second image, the second image representing a super-resolution version of the first image;
• generate a third image representing a higher-resolution version of the first image;
• perform flicker detection based on the third image and the second image in order to identify one or more flicker regions;
• perform frequency decomposition of the third image to generate first decomposed images and of the second image to generate second decomposed images;
• and
• blend portions of at least some of the first and second decomposed images based on the one or more identified flicker regions to generate a flicker-suppressed image.

A non-transitory machine readable medium containing instructions that when executed cause at least one processor of an electronic device to:

• obtain a first image and a second image, the second image representing a super-resolution version of the first image;
• generate a third image representing a higher-resolution version of the first image;
• perform flicker detection based on the third image and the second image in order to identify one or more flicker regions;
• perform frequency decomposition of the third image to generate first decomposed images and of the second image to generate second decomposed images;
• and
• blend portions of at least some of the first and second decomposed images based on the one or more identified flicker regions to generate a flicker-suppressed image.
