Method to reject false positives detecting and tracking image objects

摘要

Methods, apparatuses, systems, and computer-readable media for rejecting false positive detection and tracking of image objects are presented. According to one or more aspects, a computing device may implement embodiments of the invention to use the movement of the mobile device for distinguishing false positives from true movement of the mobile device depicted in the field of view of the camera. In one embodiment, the actual movement of the mobile device may be measured using multi-modal sensor data from inertial sensors such as accelerometers and gyroscopes. In another embodiment, the actual movement of the device is calculated using the global movement of the mobile phone with reference to other objects in the field of view of the camera.

1. A method for rejecting information using a mobile device, the method comprising:
obtaining a video frame using a camera coupled to the mobile device; detecting an at least one portion of the video frame at least partially representing a feature; identifying a first shift associated with the at least one portion of the video frame; identifying a second shift associated with an entire video frame, wherein the second shift associated with the entire video frame is identified using motion calculated from portions of the video frame that are distinct from the at least one portion of the video frame; determining a disparity between the first shift and the second shift; determining flickering in a detection of the feature by determining that the disparity is higher than a predetermined threshold; and rejecting the at least one portion of the video frame at least partially representing the feature as a false positive detection due to flickering.
