Abstract: Various implementations disclosed herein include devices, systems, and methods that provide a 3D room plan that combines 2D shapes representing elements of a room that are approximately planar (e.g., walls, wall openings, windows, doors, etc.) with 3D primitives representing non-planar elements (e.g., tables, chairs, appliances, etc.). A 3D room plan is a 3D representation of a room or other physical environment that generally identifies or otherwise represents 3D positions of one or more walls, floors, ceilings, other boundaries, other regions, windows, doors, openings, and 3D objects (e.g., objects having significant height, width, and depth in 3 dimensions) within the environment. For example, a 3D floor plan using 2D shapes to represent walls, windows, doors, etc. may be combined with 3D primitives such as 3D bounding boxes representing 3D objects to form a 3D room plan.

Abstract: Techniques described herein provide efficient object detection and tracking in video images, such as may be used for real-time camera control in power-limited mobile image capture devices. The techniques include performing object detection on a first subset of frames of an input video, detecting an object and object location in a first detection frame of the first subset of frames, and tracking the detected object on a second subset of frames of the input video after the first detection frame.

Abstract: Techniques described herein provide efficient object detection and tracking in video images, such as may be used for real-time camera control in power-limited mobile image capture devices. The techniques include performing object detection on a first subset of frames of an input video, detecting an object and object location in a first detection frame of the first subset of frames, and tracking the detected object on a second subset of frames of the input video after the first detection frame, wherein the second subset does not include frames of the first subset.
