Patent number: 10462445Abstract: A method for improving accuracy of depth map information derived from image data descriptive of a scene. In one embodiment Mutual Feature Map data are created based on initial disparity map data values and the image data descriptive of the scene. The Mutual Feature Map data are applied to create a series of weighting functions representing structural details that can be transferred to the first disparity values to restore degraded features or replace some of the first disparity values with values more representative of structural features present in the image data descriptive of the scene.Type: GrantFiled: July 19, 2017Date of Patent: October 29, 2019Assignee: FotoNation LimitedInventors: Hossein Javidnia, Peter Corcoran

Patent number: 10452910Abstract: A method of image processing within an image acquisition device. In one embodiment an image including one or more face regions is acquired and one or more iris regions are identified within the one or more face regions. The one or more iris regions are analyzed to identify any iris region containing an iris pattern that poses a risk of biometrically identifying a subject within the image. Responsive to identifying any such iris region, a respective substitute iris region, containing an iris pattern distinct from the identified iris pattern to avoid identifying the subject within the image, is determined and the identified iris region is replaced with the substitute iris region in the original image.Type: GrantFiled: March 27, 2015Date of Patent: October 22, 2019Assignee: FotoNation LimitedInventors: Ilariu Raducan, Ruxandra Vranceanu, Razvan Condorovici, Cosmin Stan, Peter Corcoran

Patent number: 10455147Abstract: A method of processing an image comprises: acquiring an image of a scene including an object having a recognizable feature. A lens actuator setting providing a maximum sharpness for a region of the image including the object and a lens displacement corresponding to the lens actuator setting are determined. A distance to the object based on the lens displacement is calculated. A dimension of the feature as a function of the distance to the object, the imaged object size and a focal length of a lens assembly with which the image was acquired, is determined. The determined dimension of the feature is employed instead of an assumed dimension of the feature for subsequent processing of images of the scene including the object.Type: GrantFiled: December 9, 2015Date of Patent: October 22, 2019Assignee: FotoNation LimitedInventors: Alexandru Malaescu, Florin Nanu, Stefan Petrescu, Peter Corcoran, Petronel Bigioi

Publication number: 20190273867Abstract: A method of estimating motion between a pair of image frames of a given scene comprises calculating respective integral images for each of the image frames and selecting at least one corresponding region of interest within each frame. For each region of interest, an integral image profile from each integral image is calculated, each profile comprising an array of elements, each element comprising a sum of pixel intensities from successive swaths of the region of interest for the frame. Integral image profiles are correlated to determine a relative displacement of the region of interest between the pair of frames. Each region of interest is divided into a plurality of further regions of interest before repeating until a required hierarchy of estimated motion for successively divided regions of interest is provided.Type: ApplicationFiled: March 11, 2019Publication date: September 5, 2019Applicant: FotoNation LimitedInventors: Petronel BIGIOI, Peter CORCORAN, Piotr STEC

Patent number: 10402846Abstract: A method of responding to a criterion-based request for information collected from users meeting the criterion while complying with a user-requested privacy requirement. In one embodiment a request is received for data comprising facial or audio expressions for users who meet the criterion. A program monitors activities indicative of user attention or user reaction based on face tracking, face detection, face feature detection, eye gaze determination, eye tracking, audio expression determination, or determination of an emotional state. When a user requests a high level of privacy, the timestream data collected for the user is aggregated with timestream data collected for other users into a statistical dataset by processing the timestreams to ensure the high level of privacy in the statistical dataset which is provided to a content provider without providing data collected for the user who has requested the high level of privacy.Type: GrantFiled: May 20, 2014Date of Patent: September 3, 2019Assignee: FotoNation LimitedInventors: Petronel Bigioi, Peter Corcoran

Patent number: 10346677Abstract: Techniques for identifying a person in a target image are described. According to one of the techniques, identifying a person in a target image involves displaying, within a graphical user interface, an image that depicts one or more faces. One or more faces are automatically detected within the image. A user provides input that selects a face of the one or more faces to be a currently-selected face. A set of images are selected from a collection of images, where the set of images includes images that closely match the currently-selected face. Concurrently with display of the currently-selected face, each image in the set of images is displayed. Within the graphical user interface, a control is provided. The control enables a user to select a target image from the set of images. In response to detecting that the user has selected a target image using the control, the currently-selected face is associated with a person to which the target image corresponds.Type: GrantFiled: September 29, 2017Date of Patent: July 9, 2019Assignee: FotoNation LimitedInventors: Eran Steinberg, Peter Corcoran, Yury Prilutsky, Petronel Bigioi, Mihai Ciuc, Stefanita Ciurel, Constantin Vertan

Patent number: 10331960Abstract: Methods for detecting, identifying and displaying object information with a multi-camera vision system. In one embodiment presence of an object is detected in a region extending above a surface and positioned beyond a border, the region including at least first and second zones. A frame of image data is acquired which spans a field of view angle corresponding to a portion of a region from a position along the border. Object detection criteria are applied to analyze and classify an image of an object among a set of object types. A determination is made whether the object is present in the first zone based on application of a first series of scan windows varying in size over a first range of window sizes relative to the size of the image frame, this only permitting detection of images limited in size to a first range of image sizes.Type: GrantFiled: May 10, 2017Date of Patent: June 25, 2019Assignee: FotoNation LimitedInventor: Peter Corcoran

Publication number: 20180332219Abstract: An embodiment of a vision system wearable by a user provides enhanced awareness of activities in a surrounding scene. A helmet permits a direct view of portions of the scene with unaided, natural vision. System components include a processing and control unit, multiple cameras positioned along an outside surface of the helmet, sensors providing signals indicative of velocity or acceleration, and a pair of displays. Based on image frames derived from the cameras, the processing and control unit provides images for presentation on the displays based on programmably adjustable fields of view, enabling simultaneous viewing on the displays of selectable fields of view while the user continues to receive direct views of the scene with unaided, natural vision. In an embodiment of a related method, frames of video data from different fields of view are monitored for detection of a potential threat based on a criterion for classifying an object.Type: ApplicationFiled: July 19, 2017Publication date: November 15, 2018Inventor: Peter CORCORAN
