BDCT的音标

The reason that Block Discrete Cosine Transform ( BDCT) brings blocking artifacts is analyzed in this paper. An efficiently adaptive de-blocking algorithm is proposed based on maximum a posteriori estimation of Markov Random Field ( MRF-MAP) Frame.

分析了块离散余弦变换（BDCT）图像编码的块效应产生原因，基于马尔可夫随机场最大后验估计（MRF-MAP）框架提出了一种有效的自适应去块效应算法。

In order to reduce the visible blocking artifacts at the block boundary with Block Discrete Cosine Transform ( BDCT) at low bit rates, a new blocking-artifact reduction algorithm in DCT domain is presented in this paper.

为了减少低比特率时块离散余弦变换（BDCT）在块边界所出现的明显可见的方块效应，提出了一种新的DCT域的去块效应消除算法。

The block-Based Discrete Cosine Transform ( BDCT) suffers from visible blocking artifacts between adjacent image blocks at low bit rates, which reduces the image visual quality.

块离散余弦变换在低比特率时其恢复图像的块边界上会出现明显可见的方块效应，从而降低了图像的视觉质量。
