W - based fog is used when a perspective projection matrix is specified , but affine projections still use z - based fog 如果指定了透视投影矩阵,将使用基于w的雾化,但仿射投影仍然使用基于z的雾化。
The 2d affine projection model is analyzed from geometrical relation of parallel projection , the conversion of projection , the foundation of strict mathematical model of 2d affine . the characteristics of 2d affine projection are illustrated by experiments 从平行投影的几何关系分析、投影性质的转换、严格仿射变换数学模型的建立等方面,深入研究了基于仿射变换的传感器模型,给出了实验结果和分析结论。
To solve the tradeoff between congverence and computational complexity , befap is proposed in chapter 3 , which is based on block - exact processing and affine projection algorithm . chapter 4 offers hardware and software implementation of the acoustic echo canceller based on tms320vc5409 dsp , which can be applied to a terminal of the tele - conference or video - conference 为了在收敛速度和运算量之间得到很好的折中,第三章提出了一种基于仿射投影算法和精确块技术的快速的自适应算法( befap算法) ,并对该算法作了详细的分析和研究。
