Patent number: 8446456Abstract: Provides a system for detecting an intersection between more than one panoramic video sequence and detecting the orientation of the sequences forming the intersection. Video images and corresponding location data are received. If required, the images and location data is processed to ensure the images contain location data. An intersection between two paths is then derived from the video images by deriving a rough intersection between two images, determining a neighborhood for the two images, and dividing each image in the neighborhood into strips. An identifying value is derived from each strip to create a row of strip values which are then converted to the frequency domain. A distance measure is taken between strips in the frequency domain, and the intersection is determined from the images having the smallest distance measure between them.Type: GrantFiled: September 7, 2007Date of Patent: May 21, 2013Assignee: Fuji Xerox Co., Ltd.Inventors: Jonathan T. Foote, Donald G. Kimber, Xinding Sun, John E. Adcock

Patent number: 8126155Abstract: An audio device management system (ADMS) manages remote audio devices via user selections in video links. The system enhances audio acquisition quality by receiving and processing human suggestions, forming customized two-way audio links according to user requests, and learning audio pickup strategies and camera management strategies from user operations. The ADMS control interface for a remote user provides a multi-window GUI that provides an overview window and selection display window. The ADMS provides users with more flexibility to enhance audio signals according to their needs and makes it more convenient to form customized two-way audio links without requiring users to remember a list of phone numbers. The ADMS also automatically manages available microphones for audio pickup based on microphone sound quality and the system's past experience when users monitor a structured audio environment without explicitly expressing their attentions in the video window.Type: GrantFiled: July 2, 2003Date of Patent: February 28, 2012Assignee: Fuji Xerox Co., Ltd.Inventors: Qiong Liu, Donald G. Kimber, Jonathan T. Foote, Chunyuan Liao, John E. Adcock

Patent number: 7925081Abstract: Systems and computer-implemented methods for use in body pose estimation are provided. Training data is obtained, where the training data includes observation vector data and corresponding pose vector data for a plurality of images. The observation vector data is representative of the images in observation space. The pose vector data is representative of the same images in pose space. Based on the training data, a model is computed that includes parameters of mapping from the observation space to latent space, parameters of mapping from the latent space to the pose space, and parameters of the latent space. The latent space has a lower dimensionality than the observation space and the pose space.Type: GrantFiled: December 12, 2007Date of Patent: April 12, 2011Assignee: Fuji Xerox Co., Ltd.Inventors: Abhinav Gupta, Trista Pei-chun Chen, Francine R.

Patent number: 7916944Abstract: Foreground segmentation in real world dynamic scenes, including under various lighting and shadow conditions, is disclosed. It may be used with one or multiple cameras for various automated tasks, such as classification of moving object, tracking moving objects, and event detection in various indoor or outdoor environments. Pixel to pixel subtraction is performed on each frame, followed by a feature-level based foreground segmentation to properly validate the foreground pixels. In this step, for each pixel in the image, a neighborhood of pixels is selected, and the aggregate change in the neighborhood image is used to classify foreground and background pixels. Normalized cross correlation is then applied to the neighborhood of each pixel that was confirmed to be foreground pixel.Type: GrantFiled: January 31, 2007Date of Patent: March 29, 2011Assignee: Fuji Xerox Co., Ltd.Inventors: Tao Yang, Francine Chen, Donald G.

Patent number: 7775439Abstract: Passive wands, tracked by one or more cameras, are used as user interface devices. The wands are inexpensive, and are a natural way for users to interact with devices such as large displays. Each wand may be used to specify a full 6 degrees of freedom, which can be helpful for manipulation of 3D applications. The wands may also be used to identify 3D world points, which is useful for multi-camera calibration, and for building 3D models of physical spaces. The described methods provide a more precise estimation of wand pose, and can be implemented with a single camera. Also described is a method for estimation wand pose using information available along a one dimensional ‘line scan’ within the image, which simplifies processing.Type: GrantFiled: February 28, 2007Date of Patent: August 17, 2010Assignee: Fuji Xerox Co., Ltd.Inventors: Donald G.

Publication number: 20090002489Abstract: Visual tracking of multiple objects in a crowded scene is critical for many applications include surveillance, video conference and human computer interaction. Complex interactions between objects result in partial or significant occlusions, making tracking a highly challenging problem. Presented is a novel efficient approach to tracking a varying number of objects through occlusion. The object tracking during occlusion is posed as a track-based segmentation problem in the joint-object space. Appearance models are used to interpret the foreground into multiple layer probabilistic masks in a Bayesian framework. The search for optimal segmentation solution is achieved by a greedy searching algorithm and integral image for real-time computing. Promising results on several challenging video surveillance sequences have been demonstrated.Type: ApplicationFiled: June 29, 2007Publication date: January 1, 2009Applicant: FUJI XEROX CO., LTD.Inventors: Tao Yang, Francine Chen, Donald G.

Patent number: 7260771Abstract: A method for creating multimedia meeting minutes is disclosed. In an embodiment, the method receives notations from a user. As each notation is received, context information is recorded with the notation. The context information is used to select pertinent portions of multimedia information received concurrently with the notations. An association is then created between the notation and each selected portion of the multimedia information. These associations may be used to access the selected portions of the multimedia information from the notations. The notations and their respective associations are deposited for future retrieval. The deposited notations may be revised by receiving an altered copy of the notations from a user. The deposited notations are modified in accordance with the altered copy.Type: GrantFiled: April 26, 2001Date of Patent: August 21, 2007Assignee: Fuji Xerox Co., Ltd.Inventors: Patrick Chiu, Donald G.
