Drimbarean Alexandru, Bigioi Petronel, Pososin Alexei, Steinberg Eran, Prilutsky Yury, Corcoran Peter: Optimized red-eye filter method and apparatus involving subsample representations of selected image regions. Fotonation Vision, Drimbarean Alexandru, Bigioi Petronel, Pososin Alexei, Steinberg Eran, Prilutsky Yury, Corcoran Peter, BOYCE Conor, August 18, 2005: WO/2005/076217 (33 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 ...

Steinberg Eran, Bigioi Petronel, Corcoran Peter, Gangea Mihnea, Petrescu Stefan Mirel, Vasiliu Andrei, Costache Gabriel, Drimbarean Alexandru: Face searching and detection in a digital image acquisition device. Fotonation Vision, Steinberg Eran, Bigioi Petronel, Corcoran Peter, Gangea Mihnea, Petrescu Stefan Mirel, Vasiliu Andrei, Costache Gabriel, Drimbarean Alexandru, CONOR Boyce, September 12, 2008: WO/2008/107002 (30 worldwide citation)

A method of detecting a face in an image includes performing face detection within a first window of the image at a first location. A confidence level is obtained from the face detection indicating a probability of the image including a face at or in the vicinity of the first location. Face detectio ...

Corcoran Peter, Steinberg Eran, Bigioi Petronel, Drimbarean Alexander, Zamfir Adrian, Florea Corneliu: Image acquisition method and apparatus. Fotonation Vision, Corcoran Peter, Steinberg Eran, Bigioi Petronel, Drimbarean Alexander, Zamfir Adrian, Florea Corneliu, SMITH Andrew, December 13, 2007: WO/2007/143415 (24 worldwide citation)

An image acquisition sensor of a digital image acquisition apparatus is coupled to imaging optics for acquiring a sequence of images. Images acquired by the sensor are stored. A motion detector causes the sensor to cease capture of an image when the degree of movement in acquiring the image exceeds ...

An image processing technique includes acquiring a main image of a scene and determining one or more facial regions in the main image. The facial regions are analysed to determine if any of the facial regions includes a defect. A sequence of relatively low resolution images nominally of the same sce ...

Corcoran Peter, Steinberg Eran, Bigioi Petronel, Drimbarean Alexandru, Petrescu Stefan Mirel: Real-time face tracking in a digital image acquisition device. Fotonation Vision, Corcoran Peter, Steinberg Eran, Bigioi Petronel, Drimbarean Alexandru, Petrescu Stefan Mirel, BOYCE Conor, February 14, 2008: WO/2008/017343 (19 worldwide citation)

An image processing apparatus for tracking faces in an image stream iteratively receives an acquired image from the image stream potentially including one or more face regions. The acquired image is sub-sampled at a specified resolution to provide a sub- sampled image. An integral image is then calc ...
