An electronic device is provided. The electronic apparatus includes a preprocessor configured to determine a repeated image frame in an image frame and perform an inverse conversion image processing only on one image frame in each image frame set consisting of the repeated image frame, and a frame rate converter configured to perform a frame rate conversion by using the image frame output from the preprocessor.

A method for decoding image frames at a client is described. The method includes generating an estimated image frame after receiving an encoded image frame of a stream of encoded image frames. The method further includes decoding the encoded image frame when the encoded image frame is received at a decode interval set for a frame rate of presentation. The method includes using the estimated image frame when a corresponding encoded image frame fails to arrive within the stream for presentation at the frame rate.

Technologies and implementations for de-interlacing an interlaced digital video and up-converting a frame rate of a digital video are generally disclosed.

Embodiments of the disclosure provide systems and methods for performing frame rate up-conversion of video data including a sequence of image frames. The method may include determining a set of motion vectors of a target frame relative to a plurality of reference frames. The target frame is to be generated and interpolated into the sequence of image frames. The method may further include performing a motion vector classification on the set of motion vectors to generate a target object map for the target frame. The method may additionally include projecting the target object map onto the plurality of reference frames to generate a plurality of reference object maps based on the set of motion vectors. The method may additionally include detecting an occlusion area in the target frame based on the set of motion vectors, the target object map, and the plurality of reference object maps.

A method of frame rate conversion includes receiving multiple input frames including a previous frame, a current frame and a next frame. A changing trend between the current frame and the previous frame is calculated. The current frame is used for generating one or more than one inserting frame according to the changing trend. The inserting frame is output after outputting the current frame to achieve frame conversion.

A method and an apparatus for determining a small-object region in a video frame. The method includes dividing a current video frame into at least two regions, and determining a global motion vector corresponding to each region; determining an interframe motion vector of each group of adjacent frames in multiple video frames that include the current video frame and a reference frame of the current video frame; determining a candidate small-object region in the current video frame according to the interframe motion vector of the each group of adjacent frames and the determined global motion vector corresponding to each region; and performing filtering on the candidate small-object region in the current video frame, and determining a region obtained after the filtering as a small-object region in the current video frame.

Apparatuses, systems, and techniques to generate interpolated video frames. In at least one embodiment, an interpolated video frame is generated based, at least in part, on a first set of pixel data sampled from a first video frame, and a second set of pixel data sampled from a second video frame based, at least in part, on a set of forward pointing motion vectors from the first video frame to the second video frame.

A system for frame rate conversion of a video that includes the use of key points.

A phase information generator generates phase information indicating a phase an interpolation-frame. An extracted pixel determination unit generates first and second motion vector crossing pixels at which the motion vector detected for generating an interpolation-pixel intersects with the first and second frames, and determines extracted pixels based on the motion vector crossing pixels. An interpolation-phase selector selects an interpolation phase based on the phase information and whether or not the first and second motion vector crossing pixels are out of an effective pixel range. An interpolation-pixel generator generates the interpolation-pixel based on the first and second extracted pixels and the interpolation phase.
