识别过程中,数码管二值化后的图像在水平轴上的投影,其上升沿或下降沿基本呈现直线的形状,尝试把最小二乘法应用于倾斜校正。
For recognition, the front or trailing edge of projection of binary image on horizontal axis basically shows linear shape, so least square theory is applied in tilt correction.
相反的,慢慢地尝试建立由4或5wpm的速度上升,达到10wpm瓶颈,会看到很长一段时间没有进展。
Contrast that to slowly trying to build speed up from 4 or 5 WPM, then hitting the plateau at 10 WPM and seeing no progress for a long time.
