这两款微型相机还有一些技术方面的改进，不过没那么明显，不如内置投影仪或双液晶屏引人注目。
These two compact cameras also feature less obvious technical advances that aren't quite as eye-catching as a built-in projector or dual LCD screens.
投影图波动明显，但噪声比较大，影响骨化中心定位结果，因此去除投影噪声非常重要。
The graph of phalange projection has obvious fluctuations but has much noise which will influence the results of ossification center location, so it is very important to reduce noise of projection.
因此提出了改进的偏折层析滤波反投影算法，数值模拟表明，改进算法在有效抑制倾斜现象的同时，对重建结果不会造成明显的失真。
Results show that the effect of projection noise on the reconstructed fields is represented by a slope function related to the filter used in deflection tomographic filtered back-projection algorithm.
基于动力系统模型的局部投影非线性降噪算法，对混沌信号和一大类非平稳信号具有明显的降噪效果。
The algorithm of local projective nonlinear noise reduction based on nonlinear dynamic system is more effective for noise reduction of chaotic signal and non-stationary signals.
在持续改进的精神下，这些投影片可能有所更动，如果注解有很明显的变更，我将会新版本带到课堂上。
In the spirit of continuous improvement, the slides may also be changed. If I make dramatic changes to the notes I will try to bring new copies to class.
