A new kind of binary phase codes two frequency cascade PN intercepted codes (TFCPIC) is presented, and its signal processing is also discussed in detail.
本文提出了一种新的二相编码波形-双频级联pn截断码，并对其信号处理作了详细讨论。
Most of non-text CCs are filtered out by cascade classifier and the remaining CCs are further verified by SVM. The final outputs are binary images containing texts only.
由于文本连通分量和非文本连通分量在特征上存在差异，大多数非文本会被级联分类器丢弃，而SVM则能在此结果上做进一步的验证，因此最终输出只有文本的二值图像。
