从大量的护目镜中，我只能找到其中几个作为 tesseract 的 setVariable(1st param, 2nd param) 的示例
tesseract->SetVariable("tessedit_char_whitelist", "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ");
tesseract->SetVariable("language_model_penalty_non_freq_dict_word", "0");
tesseract->SetVariable("language_model_penalty_non_dict_word", "0");
tesseract->SetVariable("tessedit_char_blacklist", "xyz");
tesseract->SetVariable("classify_bln_numeric_mode", "1");
我想知道还有多少？
有没有可用的清单？如果有请给我它的链接。
