Pet eye correction
Correction of color defects in a pupil represented in a digital image is disclosed. For example, a location in the pupil within the digital image is identified, and a target color to be corrected is computed based at least upon an analysis of pixels within a first region in which the location resides. Defect pixels in a second region in which the location resides are identified, the defect pixels being identified as having a pixel color similar to the target color. The defect pixels are color-corrected. For pupils that appear all white, appropriately configured pupil images are inserted therein.
1. A method implemented at least in part by a computer system, the method for correcting color defects in a pupil represented in a digital image, and the method comprising the steps of:
identifying an expected pupil-location within the digital image;
determining that all or substantially all of the pixels within a particular region in which the expected pupil-location resides have a white or a substantially white color;
identifying a presumed pupil region; and
inserting into the presumed pupil region an image of a pupil configured to fit the presumed pupil region when all or substantially all of the pixels within a particular region in which the expected pupil-location resides have a white or a substantially white color.
2. The method of claim 1 , wherein the image of the pupil includes an image of an iris.
