黎智英欺詐案上訴得直:定罪及刑罰被撤銷,出獄時間提前
Due to this more measured approach, error-diffusion dithering is even better at preserving details and can produce a more organic looking final image. However, the algorithm itself is inherently serial and not easily parallelised. Additionally, the propagation of error can cause small discrepancies in one part of the image to cascade into other distant areas. This is very obvious during animation, where pixels will appear to jitter between frames. It also makes files harder to compress.

接下来是“拍照”,用高能电子束照射样本。由于电子的波长只有可见光的几千分之一,其成像精度可达原子级别。配合高灵敏度的直接电子探测器(类似于数码相机中的图像传感器CCD),可以精准捕捉穿过样本的电子信号,生成大量清晰的二维投影图像。
