Abstract
A disclosed computer-implemented method may include (1) selecting, from a video stream, a reference frame and a current frame, (2) collecting a reference histogram of the reference frame and a current histogram of the current frame, and (3) generating a smoothed reference histogram by applying a smoothing function to at least a portion of the reference histogram. In some examples, the computer-implemented method may also include (1) determining a similarity metric between the smoothed reference histogram and the current histogram and, (2) when the similarity metric is greater than a threshold value, applying weighted prediction during a motion estimation portion of an encoding of the video stream. Various other methods, systems, and computer-readable media are also disclosed.
