Fast Macroblock Mode Determination to Reduce H.264 Complexity
نویسندگان
چکیده
The rate-distortion optimization (RDO) method is an informative technology that improves the coding efficiency, but increases the computational complexity, of the H.264 encoder. In this letter, a fast Macroblock mode determination algorithm is proposed to reduce the computational complexity of the H.264 encoder. The proposed method reduces the encoder complexity by 55%, while maintaining the same level of coding efficiency. key words: H.264, rate-distortion optimization (RDO), variable block size motion estimation (ME), discrete cosine transform (DCT)

In this paper, we propose a fast HVS-based mode decision algorithm to reduce the computational complexity of H.264/AVC. First, we use the Just Noticeable Difference (JND) visual model to analyze the residual data, then utilize the result to forecast the structure in an macroblock.

متن کاملEfficient intra- and inter-mode selection algorithms for H.264/ AVC
Intra-frame mode selection and inter-frame mode selection are new features introduced in the H.264 standard. Intra-frame mode selection dramatically reduces spatial redundancy in Iframes, while inter-frame mode selection significantly affects the output quality of P-/Bframes by selecting an optimal block size with motion vector(s) or a mode for each macroblock. Unfortunately, this feature requi...

To more effectively reduce temporal and spatial redundancy in the MPEG-4 Part-10 AVC/H.264, motion compensation uses variable block sizes and directional inter prediction investigates all available coding modes to determine the best one. However, these functions are performed for all variable block sizes, high complexity results due to the large number of combinations of coding modes. The resea...

501 Abstract—In the H.264/ AVC video coding standard, the intra-prediction coding with various block sizes offers a considerably high improvement in coding efficiency compared to previous standards. In order to achieve this, H.264/AVC uses the Rate-distortion optimization (RDO) technique to select the best intra-prediction mode for a macroblock, and it brings about the drastic increase of the c...
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...
