Peter Corcoran, Eran Steinberg, Stefan Petrescu, Alexandru Drimbarean, Florin Nanu, Alexei Pososin, Petronel Biglol: Real-time face tracking in a digital image acquisition device. FotoNation Vision, Jackson & Co, Andrew V Smith, January 1, 2008: US07315631 (216 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 calcu ...

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 ...

Peter Corcoran, Eran Steinberg, Petronel Bigioi, Alexandru Drimbarean, Adrian Zamfir, Corneliu Florea: Image acquisition method and apparatus. DigitalOptics Corporation Europe, Andrew V Smith, May 1, 2012: US08169486 (88 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 ...

Alexandru Drimbarean, Peter Corcoran, Eran Steinberg: Image blurring. FotoNation Vision, Andrew V Smith, December 23, 2008: US07469071 (60 worldwide citation)

A method of blurring an image includes acquiring two images of nominally a same scene taken at a different light exposure levels. At least one region of one of the images includes pixels having saturated intensity values. For at least one of the saturated pixels, values are extrapolated from the oth ...
