To improve the rate-distortion (RD) performance of low delay (LD) High Efficiency Video Coding (HEVC) encoding while enabling scene-based non-linear editing feature (NLEF), in this paper, we present a new scene-based LD HEVC encoding framework in which scene change (SC) detection and coding are conducted jointly. A frame in a sequence to be encoded is deemed a SC if there is a sudden change in the...
Video retrieval and video copy detection are well studied problems. The goal is to find the matching video in a database from a given query video. Typically, these query videos are short and aligning the query video is of secondary importance. Short sequences can be aligned using dynamic time warping. But, since time and memory usage increases quadratically with the length of the sequences, such process...
This paper proposes a history-based tiling algorithm aiming at the increase of speedup when using Tiles. The algorithm is composed of two independent steps that use workload history information to define the vertical and horizontal boundaries of the Tiles. The workload distribution of previous frames are used as reference to perform the tiling of the current frame exploiting the temporal similarity...
