Patent number: 8155397Abstract: A method operable in a digital image acquisition system having no photographic film is provided. The method comprises receiving a relatively low resolution image of a scene from an image stream, wherein the scene potentially includes one or more faces. At least one high quality face classifier is applied to the image to identify relatively large and medium sized face regions and at least one relaxed face classifier is applied to the image to identify relatively small sized face regions. A relatively high resolution image of nominally the same scene is received and at least one high quality face classifier is applied to the identified small sized face regions in the higher resolution version of said image.Type: GrantFiled: September 26, 2007Date of Patent: April 10, 2012Assignee: DigitalOptics Corporation Europe LimitedInventors: Petronel Bigioi, Alexei Pososin, Mihnea Gangea, Stefan Petrescu, Peter Corcoran

Patent number: 8131021Abstract: The detection of red-eye defects is enhanced in digital images for embedded image acquisition and processing systems. A two-stage redeye filtering system includes a speed optimized filter that performs initial segmentation of candidate redeye regions and optionally applies a speed-optimized set of falsing/verification filters to determine a first set of confirmed redeye regions for correction. Some of the candidate regions which are rejected during the first stage are recorded and re-analyzed during a second stage by an alternative set of analysis-optimized filters to determine a second set of confirmed redeye regions.Type: GrantFiled: April 4, 2011Date of Patent: March 6, 2012Assignee: DigitalOptics Corporation Europe LimitedInventors: Yury Prilutsky, Eran Steinberg, Peter Corcoran, Alexei Pososin, Petronel Bigioi, Mihai Ciuc

Publication number: 20120038788Abstract: A method of filtering a red-eye phenomenon from an acquired digital image including a multiplicity of pixels indicative of color, the pixels forming various shapes of the image, includes analyzing meta-data information, determining one or more regions within the digital image suspected as including red eye artifact, and determining, based at least in part on the meta-data analysis, whether the regions are actual red eye artifact. The meta-data information may include information describing conditions under which the image was acquired, captured and/or digitized, acquisition device-specific information, and/film information.Type: ApplicationFiled: September 19, 2011Publication date: February 16, 2012Applicant: DIGITALOPTICS CORPORATION EUROPE LIMITEDInventors: Michael J.

Publication number: 20110129121Abstract: 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 calculated for a least a portion of the sub-sampled image. Fixed size face detection is applied to at least a portion of the integral image to provide a set of candidate face regions. Responsive to the set of candidate face regions produced and any previously detected candidate face regions, the resolution is adjusted for sub-sampling a subsequent acquired image.Type: ApplicationFiled: January 3, 2011Publication date: June 2, 2011Applicant: TESSERA TECHNOLOGIES IRELAND LIMITEDInventors: Peter Corcoran, Alexandru Drimbarean, Alexei Pososin, Petronel Bigioi, Eran Steinberg, Stefan Petrescu, Florin Nanu
