Patent number: 11494880Abstract: Embodiments relate to generating an image pyramid for feature extraction. A pyramid image generator circuit includes a first image buffer that stores image data at a first octave, a first blur filter circuit, a first spatial filter circuit, and a first decimator circuit. The first blur filter circuit generates a first pyramid image for a first scale of the first octave by applying a first amount of smoothing to the first image data stored in the first image buffer. The first spatial filter circuit and the first decimator generate second image data of a second octave that is higher than the first octave by applying a smoothing and a decimation to the first image data stored in the first image buffer. The first spatial filter circuit begins processing the first image data before the first blur filter circuit begins to process the first image data.Type: GrantFiled: March 19, 2021Date of Patent: November 8, 2022Assignee: Apple Inc.Inventors: David R.

Patent number: 11486836Abstract: A non-transitory computer readable medium on which is stored machine-readable instructions that, when executed by at least one processor, cause the processor to determine the location in 3D space of an object of interest within the interior region of an opaque container. Hence, a user or operator is allowed to construct a three-dimensional representation of the interior region of the opaque container so as to allow viewing of objects, components and substances within the interior region. The users or operators now have the opportunity to isolate a particular object of interest within the interior region that may be a threat, such as an explosive device or other energetic component. A disrupter device is aimed at the three-dimensional location and thereafter, the disrupter device fires a projectile or substance at the object of interest in order to disable or destroy the object of interest.Type: GrantFiled: June 29, 2020Date of Patent: November 1, 2022Assignee: The United States of America as represented by the Secretary of the NavyInventors: Angel Diaz, David Rivera-Marchand, Lonnie Frericks, Anthony Wojkowski, Anthony Kummerer

Patent number: 11386609Abstract: An approach using 3D algorithms to solve 2D head localization problems is disclosed. A system can extrapolate aspects of one part of an object, e.g., extract characteristics of a person's head, using a 2D input image of another part of the object, e.g., a 2D image of the person's face. The system then selects an appropriate 3D model by the use of facial features detected in an image of a person's face. Using the selected 3D model and the 3D rotation angles provided by a face detector, the system rotates the model and then projects the model to a 2D shape. The system then scales and translates, e.g., transforms, the 2D shape to match the 2D face bounding box. Then, using the transformed 2D shape, the system extracts a bounding box for the extracted portion of an object, e.g., the head of the person depicted in the 2D input image.Type: GrantFiled: December 30, 2020Date of Patent: July 12, 2022Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Mattan Serry, Zvi Figov, Irit Ofer
