Abstract: Disclosed herein are exemplary embodiments of innovations in the area of encoding pictures or portions of pictures (e.g., slices, coding tree units, or coding units) and determining whether and how certain filtering operation should be performed and flagged for performance by the decoder in the bitstream. In particular examples, various implementations for setting the sample adaptive offset (SAO) syntax elements in the H.265/HEVC standard are disclosed. Although these examples concern the H.265/HEVC standard and its SAO filter, the disclosed technology is more widely applicable to other video codecs that involve filtering operations (particularly multi-stage filtering operations) as part of their encoding and decoding processes.

Abstract: A method for determining a physical state of a movable object includes determining an estimated physical state based on first sensing data obtained by a first sensing system of the movable object, during a time duration in which second sensing data from a second sensing system is unavailable or is not updated; in response to determining that the second sensing data from the second sensing system becomes available or is updated, determining an observed physical state of the movable object based on the second sensing data; and based on a deviation between the observed physical state and the estimated physical state of the movable object, determining whether to update the physical state of the movable object based on the observed physical state. The first and second sensing systems have different sampling frequencies. The deviation is indicative of a validity of the sensing data of the second sensing system.
