چکیده
In H.264, B frame bi-directional predictions and its DIRECT mode coding are included to enhance video compression efficiency. However, such tools are complex and result in a long computation time. This paper proposes a fast DIRECT mode prediction algorithm that enables to save B frame encoding time significantly by determining DIRECT mode (DM) at an early stage through optimal mode pattern matching. Simulations show that the proposed algorithm can determine DM without a complex mode decision process for 42% more macroblocks than Jin s algorithm.

متن کاملEvaluation of the Image Backtrack-Based Fast Direct Mode Decision Algorithm
B frame bi-directional predictions and the DIRECT mode coding of the H.264 video compression standard necessitate a complex mode decision process, resulting in a long computation time. To make H.264 feasible, this paper proposes an image backtrackbased fast (IBFD) algorithm and evaluates the performances of two promising fast algorithms (i.e., AFDM and IBFD). Evaluation results show that an ima...
متن کاملEfficient Mode Selection with BMA Based Pre-processing Algorithms for H.264/AVC Fast Intra Mode Decision
In a H.264/AVC intra-frame encoder, the complicated computations for the mode decision cause the difficulty in real-time applications. In this paper, we propose an efficient fast algorithm, which is called Block Matching Algorithm (BMA), to predict the best direction mode for the fast intra mode decision. The edge detective technique can predict luma-4x4, luma-16x16, and chroma-8x8 modes direct...
متن کاملAn Improved H.264 Fast Inter-mode Decision Algorithm
The H.264 video coding standard substantially improves compression performance by using more flexible coding options, notably the inter-mode selection. The introduced flexibility, however, significantly increases the encoding complexity. In this paper, a new H.264 fast inter-mode decision algorithm is presented to resolve the performance/complexity dilemma. The proposed method integrates the co...
متن کاملA New RSTB Invariant Image Template Matching Based on Log-Spectrum and Modified ICA
Template matching is a widely used technique in many of image processing and machine vision applications. In this paper we propose a new as well as a fast and reliable template matching algorithm which is invariant to Rotation, Scale, Translation and Brightness (RSTB) changes. For this purpose, we adopt the idea of ring projection transform (RPT) of image. In the proposed algorithm, two novel s...
