    Abstract: A method for processing video data of an environment includes, with aid of one or more processors individually or collectively, obtaining in or near real-time a reference position of an imaging device located on a movable object based on one or more previously traversed positions of the imaging device, and modifying an image frame in the video data to obtain a modified image frame based on the reference position of the imaging device and an actual position of the imaging device at which the image frame is taken. The one or more previously traversed positions are obtained using at least one sensor on the movable object. The video data is acquired by the imaging device.

    Abstract: A method, system, article of manufacture, and UAV configured to identify a target object shown in an image, such as shown in a perspective view that is a two-dimensional image or frame of video. The method comprises: identifying and track the position of a target object shown in a sequence of images or video, even when the target object may be traveling at high speeds, detecting the target object within an image based on one or more of the object's physical characteristics, such as its color, shape, size, chrominance, luminance, brightness, lightness, darkness, and/or other characteristics. Thus, in this context a target object may be anything having one or more detectable physical characteristics. The method also providing an improved and more intuitive user interface that enables a user to select a target object for tracking. As a result, the method and system improve the accuracy, usability, and robustness of the system.

    Abstract: A method includes obtaining an image frame captured by an imaging device carried by an unmanned vehicle and containing the target object, extracting one or more features of a target object from a region selected by a user on the image frame, and determining whether the target object is a predetermined recognizable object type based on a comparison of the one or more features with one or more characteristics associated with the predetermined recognizable object type. If the target object is the predetermined recognizable object type, tracking functions associated with the predetermined recognizable object type are initiated. IF the target object does not belong to the predetermined recognizable object type, tracking functions associated with a general object type are initiated.

    Abstract: Systems, methods, and devices are provided for providing flight response to flight-restricted altitudes. The altitude of an unmanned aerial vehicle (UAV) may be compared with an altitude restriction. If needed a flight-response measure may be taken by the UAV to prevent the UAV from flying in a restricted altitude. The altitude measurement of the UAV and/or altitude restriction of the UAV may be modified for improved performance. Different flight-response measures may be taken depending on preference and the rules of a jurisdiction within which the UAV falls.
