Publication number: 20230281970Abstract: System and methods for object segmentation include providing a pre-trained neural network model to segment object instances based on a first set of images and a first loss function. The neural network, for a pixel, can generate a gradient flow that points towards a center of an object structure and provides a probability score indicating a probability of the pixel belonging to the object structure. An adapted neural network model can be generated from the pre-trained neural network model to account for domain shifted new input images by training the pre-trained neural network model on a second set of images and a loss function that comprises a contrastive flow loss component and a contrastive mask loss component.Type: ApplicationFiled: March 7, 2023Publication date: September 7, 2023Inventors: Gianfranco DORETTO, Matthew Richardson KEATON

Patent number: 8457406Abstract: A device and method for processing an image to create appearance and shape labeled images of a person or object captured within the image. The appearance and shape labeled images are unique properties of the person or object and can be used to re-identify the person or object in subsequent images. The appearance labeled image is an aggregate of pre-stored appearance labels that are assigned to image segments of the image based on calculated appearance attributes of each image segment. The shape labeled image is an aggregate of pre-stored shape labels that are assigned to image segments of the image based on calculated shape attributes of each image segment. An identifying descriptor of the person or object can be computed based on both the appearance labeled image and the shape labeled image. The descriptor can be compared with other descriptors of later captured images to re-identify a person or object.Type: GrantFiled: March 26, 2012Date of Patent: June 4, 2013Assignee: Lockheed Martin CorporationInventors: Gianfranco Doretto, Xiaogang Wang, Thomas B.

Patent number: 8295543Abstract: A device and method for detecting targets of interest in an image, such as people or objects of a certain type. Targets are detected based on an optimized strong classifier descriptor that can be based on a combination of weak classifier descriptors. The weak classifier descriptors can include a user-defined weak classifier descriptor that is defined by a user to represent a shape or appearance attribute that is characteristic of parts of the target of interest. The strong classifier descriptor can be optimized by selecting a subset of weak classifier descriptors that exhibit improved performance in detecting targets in training images.Type: GrantFiled: March 28, 2008Date of Patent: October 23, 2012Assignee: Lockheed Martin CorporationInventors: Peter H.

Patent number: 8184915Abstract: A device and method for efficient computation of statistical information, such as a mean, co-variance, or histogram of the image pixels, over discrete image regions. The computation employs integral computations to determine the statistical information over image regions of arbitrary shape, including irregular polygonal shaped regions. The integral computations are simplified by categorizing corner points of boundaries of image regions. The computation can be applied to calculate descriptors or signatures of persons or objects within an image. The computation also has a low computational cost enabling fast calculation of image statistics.Type: GrantFiled: December 4, 2007Date of Patent: May 22, 2012Assignee: Lockheed Martin CorporationInventors: Gianfranco Doretto, Xiaogang Wang, Thomas B.
