Abstract: Systems and techniques are provided for performing an accurate object count using monocular three-dimensional (3D) perception. In some examples, a computing device can generate a reference depth map based on a reference frame depicting a volume of interest. The computing device can generate a current depth map based on a current frame depicting the volume of interest and one or more objects. The computing device can compare the current depth map to the reference depth map to determine a respective change in depth for each of the one or more objects. The computing device can further compare the respective change in depth for each object to a threshold. The computing device can determine whether each object is located within the volume of interest based on comparing the respective change in depth for each object to the threshold.

Abstract: System and techniques are described herein for processing images to detect expressions of a subject. In one illustrative example, a method of recognizing facial expressions in one or more images includes obtaining, by a computing device, a first image of a person; obtaining expression information based on the first image and an anchor image associated with the person; and determining an expression classification associated with the first image based on the expression information.

Abstract: A method for picture processing is described. A first tracking area is obtained. A second tracking area is also obtained. The method includes beginning to track the first tracking area and the second tracking area. Picture processing is performed once a portion of the first tracking area overlapping the second tracking area passes a threshold.

Abstract: Examples are described of segmenting an image into image regions based on depicted categories of objects, and for refining the image regions semantically. For example, a system can determine that a first image region in an image depicts a first category of object. The system can generate a color distance map of the first image region that maps color distance values to each pixel in the first image region. A color distance value quantifies a difference between a color value of a pixel in the first image region and a color value of a sample pixel in a second image region in the image. The system can process the image based on a refined variant of the first image region that is refined based on the color distance map, for instance by removing pixels from the first image region whose color distances fall below a color distance threshold.

Abstract: Techniques and systems are provided for tracking objects in one or more video frames. For example, based on an application of an object detector to at least one key frame in the one or more video frames, a first set of bounding regions for a video frame can be obtained. A group of bounding regions can be determined from the first set of bounding regions. A bounding region from the group of bounding regoins can be removed based on one or more metrics associated with the bounding region. Object tracking for the video frame can be performed using an updated set of bounding regions that is based on removal of the bounding region from the group of bounding regions.

Abstract: Methods, systems, computer-readable media, and apparatuses for image-based status determination are presented. In some embodiments, a method includes capturing at least one image of a moving path. At least one feature within the at least one image is analyzed and based on the analysis of the at least one feature, a direction of movement of the moving path is determined. In some embodiments, a method includes capturing an image of an inclined path. At least one feature within the image is analyzed and based on analysis of the at least one feature, a determination is made whether the image was captured from a top position relative to the inclined path or a bottom position relative to the inclined path.

Abstract: Systems and techniques are described for establishing one or more virtual sessions between users. For instance, a first device can transmit, to a second device, a call establishment request for a virtual representation call for a virtual session and can receive, from the second device, a call acceptance indicating acceptance of the call establishment request. The first device can transmit, to the second device, first mesh information for a first virtual representation of a first user of the first device and first mesh animation parameters for the first virtual representation. The first device can receive, from the second device, second mesh information for a second virtual representation of a second user of the second device and second mesh animation parameters for the second virtual representation. The first device can generate, based on the second mesh information and the second mesh animation parameters, the second virtual representation of the second user.

Abstract: Techniques are provided for generating three-dimensional models of objects from one or more images or frames. For example, at least one frame of an object in a scene can be obtained. A portion of the object is positioned on a plane in the at least one frame. The plane can be detected in the at least one frame and, based on the detected plane, the object can be segmented from the plane in the at least one frame. A three-dimensional (3D) model of the object can be generated based on segmenting the object from the plane. A refined mesh can be generated for a portion of the 3D model corresponding to the portion of the object positioned on the plane.

Abstract: Various embodiments may include methods and systems for performing synchronous multi-viewpoint photography using robotic vehicle devices. Various embodiments may include transmitting a first maneuver instruction directing a responding robotic vehicle to a position for capturing an image suitable for multi-viewpoint photography, determining whether the responding robotic vehicle is suitably positioned and oriented for capturing such an image, transmitting a second maneuver instruction to adjust the responding robotic vehicle's location and/or orientation in response to determining that the responding robotic vehicle is not suitably positioned and oriented, transmitting an image capture instruction causing the responding robotic vehicle to capture an image in response to determining that the responding robotic vehicle is suitably positioned and oriented for synchronous multi-viewpoint photography, capturing an image by the initiating robotic vehicle, receiving the image from the responding robotic vehicle, and generating an image file based on the captured and received images.

Abstract: Systems, methods, and computer-readable media are provided media for transferring visual attributes to images. In some examples, a system can obtain a first image associated with a user; generate a second image including image data from the first image modified to add a first visual attribute transferred from one or more images or remove a second visual attribute in the image data; compare a first set of features from the first image with a second set of features from the second image; determine, based on a comparison result, whether the first image and the second image match at least partially; and update a library of user verification images to include the second image when the first image and the second image match at least partially.
