Patent number: 9684966Abstract: A method for providing improved foreground/background separation in a digital image of a scene is disclosed. The method comprises providing a first map comprising one or more regions provisionally defined as one of foreground or background within the digital image; and providing a subject profile corresponding to a region of interest of the digital image. The provisionally defined regions are compared with the subject profile to determine if any of the regions intersect with the profile region. The definition of one or more of the regions in the map is changed based on the comparison.Type: GrantFiled: August 24, 2015Date of Patent: June 20, 2017Assignee: FotoNation LimitedInventors: Eran Steinberg, Peter Corcoran, Yury Prilutsky, Petronel Bigioi, Alexei Pososin, Mihai Ciuc, Adrian Zamfir, Adrian Capata

Publication number: 20170070649Abstract: 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 analyzes at least one partial face region identified within the digital image for the red-eye phenomenon and modifies the image to eliminate the red-eye phenomenon by changing the red area to black. The modification of the image is enabled when a photograph is taken under conditions indicative of the red-eye phenomenon. The modification is subject to anti-falsing analysis which further examines the area around the red-eye area for indicia of the eye of the subject. The detection and correction can be optimized for performance and quality by operating on subsample versions of the image when appropriate.Type: ApplicationFiled: August 9, 2016Publication date: March 9, 2017Inventors: Florin NANU, Eran STEINBERG, Stefan PETRESCU, Mihnea GANGEA, Adrian CAPATA, Mihai CIUC, Adrian ZAMFIR, Peter CORCORAN, Alexei POSOSIN, Petronel BIGIOI, Alexandru DRIMBAREAN

Patent number: 9280810Abstract: A method for correcting a distorted input image comprises determining a local region of an image to be displayed and dividing said region into an array of rectangular tiles, each tile corresponding to a distorted tile with a non-rectangular boundary within said input image. For each tile of the local region, maximum and minimum memory address locations of successive rows of said input image sufficient to span said boundary of said distorted tile are determined. Successive rows of the distorted input from between said maximum and minimum addresses are read. Distortion of the non-rectangular portion of said distorted input image is corrected to provide a tile of a corrected output image which is stored.Type: GrantFiled: June 2, 2015Date of Patent: March 8, 2016Assignee: FotoNation LimitedInventors: Piotr Stec, Alexei Pososin, Mihai Constantin Munteanu, Corneliu Zaharia, Vlad Georgescu

Patent number: 8861806Abstract: A method of tracking a face in a reference image stream using a digital image acquisition device includes acquiring a full resolution main image and an image stream of relatively low resolution reference images each including one or more face regions. One or more face regions are identified within two or more of the reference images. A relative movement is determined between the two or more reference images. A size and location are determined of the one or more face regions within each of the two or more reference images. Concentrated face detection is applied to at least a portion of the full resolution main image in a predicted location for candidate face regions having a predicted size as a function of the determined relative movement and the size and location of the one or more face regions within the reference images, to provide a set of candidate face regions for the main image.Type: GrantFiled: August 12, 2013Date of Patent: October 14, 2014Assignee: DigitalOptics Corporation Europe LimitedInventors: Eran Steinberg, Peter Corcoran, Petronel Bigioi, Alexei Pososin, Alexandru Drimbarean, Florin Nanu, Stefan Petrescu
