我想要扫描图像（tif 图像）来获得一个数字。当 Tess4J 设置为默认引擎时，它经常将 6 与 5 混淆，0 与 9 混淆......我想尝试使用 CUBE ONLY 引擎。
这是我的配置文件：
tessedit_ocr_engine_mode 2
load_system_dawg F
load_freq_dawg F
load_punc_dawg F
load_number_dawg F
load_unambig_dawg F
load_bigram_dawg F
load_fixed_length_dawgs F
user_words_suffix user-words
user_patterns_suffix user-patterns
这是我的 Java 代码
