Patent number: 8526694Abstract: An image data subtraction system enhances visualization of vessels subject to movement using an imaging system. The imaging system acquires data representing first and second anatomical image sets comprising multiple temporally sequential individual mask (without contrast agent) and fill images (with contrast agent) of vessels respectively, during multiple heart cycles. An image data processor automatically identifies temporally corresponding pairs of images comprising a mask image and a contrast enhanced image and for the corresponding pairs, automatically determines a shift of a contrast enhanced image relative to a mask image to compensate for motion induced image mis-alignment. The image data processor automatically shifts a contrast enhanced image relative to a mask image in response to the determined shift.Type: GrantFiled: January 24, 2011Date of Patent: September 3, 2013Assignee: Siemens Medical Solutions USA, Inc.Inventor: Michael Pajeau

Patent number: 8509488Abstract: Satellite-based navigation techniques can help determine a user's position on a map and can also determine directions to a destination. Functionality can be implemented to determine the user's orientation and direction of motion based on a captured image taken in the direction of motion. The captured image may be preprocessed to compensate for a camera angle and to vary image properties before being transmitted to a server. The user's orientation may be determined based, at least in part, on knowledge of a user's position on a map and comparing the captured image to a set of other images. Walking directions can accordingly be tailored based on the user's orientation.Type: GrantFiled: February 24, 2010Date of Patent: August 13, 2013Assignee: QUALCOMM IncorporatedInventors: Per K.

Patent number: 8406482Abstract: Systems, methods, and computer-readable storage media for automatically detecting skin tones in an input image are disclosed. An initial skin tone mask for the image may be created dependent on a general skin tone model. An upper threshold and/or a lower threshold may be applied to the initial skin tone mask to identify pixels most likely to be skin pixels and least likely to be skin pixels, respectively. These pixels may be used to produce an image-specific skin tone model, including one or more truncated Gaussian models for skin pixels and/or non-skin pixels defined in a three-dimensional color space. The image-specific skin tone model may be applied to the image to generate a final skin tone mask. Skin tone detection may be automatically or selectively performed in conjunction with image editing or image feature identification operations to target or exclude skin pixels or non-skin pixels during execution of the operations.Type: GrantFiled: August 28, 2008Date of Patent: March 26, 2013Assignee: Adobe Systems IncorporatedInventors: Jen-Chan Chien, Jue Wang
