Abstract: Video encoding computations are optimized by dynamically adjusting slice patterns of video frames based on complexity of each frame and allocating multi-core threading based on the slices.

Allocation is determined based on capacity and queue of each processing core such that overall computation performance for video encoding is improved.

Abstract: In one example, this disclosure describes filtering techniques for filtering of video blocks of a video unit. The filtering techniques may select one or more different types of filtering for each video block of the video unit based on various factors such as whether the video block is inter-coded or intra-coded, and whether adaptive interpolations were preformed during a motion compensation process during the encoding of the video block. When adaptive interpolations were performed, the adaptive interpolations may provide a level of filtering that renders additional filtering unnecessary or undesirable in some cases.

Abstract: A depth detection method includes the following steps. First, first and second video data are shot. Next, the first and second video data are compared to obtain initial similarity data including r×c×d initial similarity elements, wherein r, c and d are natural numbers greater than 1. Then, an accumulation operation is performed, with each similarity element serving as a center, according to a reference mask to obtain an iteration parameter. Next, n times of iteration update operations are performed on the initial similarity data according to the iteration parameter to generate updated similarity data. Then, it is judged whether the updated similarity data satisfy a character verification condition. If yes, the updated similarity data is converted into depth distribution data.
