Abstract:

A system for tracking a target object across a plurality of image frames. The system comprises a logic machine and a storage machine. The storage machine holds instructions executable by the logic machine to calculate a trajectory for the target object over one or more previous frames occurring before a target frame. Responsive to assessing no detection of the target object in the target frame, the instructions are executable to predict an estimated region for the target object based on the trajectory, predict an occlusion center based on a set of candidate occluding locations for a set of other objects within a threshold distance of the estimated region, each location of the set of candidate occluding locations overlapping with the estimated region, and automatically estimate a bounding box for the target object in the target frame based on the occlusion center.

G06T 3/40
G02B 27/01

Abstract:

Systems and methods for object detection generate a feature pyramid corresponding to image data, and rescaling the feature pyramid to a scale corresponding to a median level of the feature pyramid, wherein the rescaled feature pyramid is a four-dimensional (4D) tensor. The 4D tensor is reshaped into a three-dimensional (3D) tensor having individual perspectives including scale features, spatial features, and task features corresponding to different dimensions of the 3D tensor. The 3D tensor is used with a plurality of attention layers to update a plurality of feature maps associated with the image data. Object detection is performed on the image data using the updated plurality of feature maps.

International Classification:

G06K 9/62
G06V 20/40

Abstract:

The technology described herein is directed to systems, methods, and software for indexing video. In an implementation, a method comprises identifying one or more regions of interest around target content in a frame of the video. Further, the method includes identifying, in a portion of the frame outside a region of interest, potentially empty regions adjacent to the region of interest. The method continues with identifying at least one empty region of the potentially empty regions that satisfies one or more criteria and classifying at least the one empty region as a negative sample of the target content. In some implementations, the negative sample of the target content in a set of negative samples of the target content, with which to train a machine learning model employed to identify instances of the target content.

G06F 3/16

Abstract:

Augmented reality (AR) systems, devices, media, and methods are described for sending and receiving AR objects (e.g., customized AR objects) based on/responsive to interactions with the physical world. AR virtual delivery route overlays are generated responsive to selected virtual delivery routes and include the AR object and a delivery mode (air, tunnel, etc.) corresponding to the virtual delivery route. Physical world actions associated with the delivery mode (blowing adjacent an AR device or scratching a surface) result in sending a communication corresponding to the AR object for delivery to a receiver and generating AR sending overlays including the AR object moving in accordance with the delivery mode.
