MINMAX Optimal Video Summarization and Coding with Frame Skip Constraint
نویسندگان
چکیده
The need for video summarization originates primarily from a viewing time constraint. A shorter version of the original video sequence is desirable in a number of applications. Clearly, a shorter version is also necessary in applications where storage, communication bandwidth and/or power are limited. In this paper, our work is based on a MINMAX optimization formulation with viewing time, frame skip and bit rate constraints. New metrics for missing frame and video summary distortions are introduced. Optimal algorithm based on dynamic programming is presented along with experimental results. Index Terms — Rate-Distortion Optimization, Dynamic Programming, Video Analysis, Video Summarization.

Optimal Video Summarization with a Bit Rate Constraint
Video summarization offers an intelligent way of reducing the video content temporally to satisfy the user preference for a shorter viewing time, and/or to meet the bit budget limitations in storage/communications. In this paper we formulate the summarization problem as a rate-distortion optimization problem under bit budget and frame skip constraints, and introduce a summarization distortion m...
متن کاملOptimization of the Block-level Bit Allocation in Perceptual Video Coding based on MINMAX
—In video coding, it is expected that the encoder could adaptively select the encoding parameters (e.g., quantization parameter) to optimize the bit allocation to different sources under the given constraint. However, in hybrid video coding, the dependency between sources brings high complexity for the bit allocation optimization, especially in the block-level, and existing optimization methods...
متن کاملA Study on Consistency between MINAVE and MINMAX in SSIM Based Independent Perceptual Video Coding
In this letter, we study the R-D properties of independent sources based on MSE and SSIM, and compare the bit allocation performance under the MINAVE and MINMAX criteria in video encoding. The results show that MINMAX has similar results in terms of average distortion with MINAVE by using SSIM, which illustrates the consistency between these two criteria in independent perceptual video coding. ...
متن کاملFast Intra Mode Decision for Depth Map coding in 3D-HEVC Standard
three dimensional- high efficiency video coding (3D-HEVC) is the expanded version of the latest video compression standard, namely high efficiency video coding (HEVC), which is used to compress 3D videos. 3D videos include texture video and depth map. Since the statistical characteristics of depth maps are different from those of texture videos, new tools have been added to the HEVC standard fo...
متن کاملEnhanced low bitrate H.264 video coding using decoder-side super-resolution and frame interpolation
Advanced inter-prediction modes are introduced recently in literature to improve video coding performances of both H.264 and High Efficiency Video Coding standards. Decoder-side motion analysis and motion vector derivation are proposed to reduce coding costs of motion information. Here, we introduce enhanced skip and direct modes for H.264 coding using decoder-side super-resolution (SR) and fra...
