A technique for detecting large and small non-red eye flash defects in an image is disclosed. The method comprises selecting pixels of the image which have a luminance above a threshold value and labeling neighboring selected pixels as luminous regions. A number of geometrical filters are applied to ...

Michael J DeLuca, Yury Prilutsky, Eran Steinberg, Peter Corcoran, Alexei Pososin, Petronel Bigioi, Alexandru Drimbarean, Adrian Capata, Florin Nanu: Image modification based on red-eye filter analysis. Fotonation Vision, Andrew V Smith, April 1, 2008: US07352394 (127 worldwide citation)

A digital camera has an integral flash and stores and displays a digital image. Under certain conditions, a flash photograph taken with the camera may result in a red-eye phenomenon due to a reflection within an eye of a subject of the photograph. A digital apparatus has a red-eye filter which analy ...
