stats_.doc_char_quality is not always initialized in control.cpp #1450

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Using tesseract as a library and in specific input conditions, Valgrind 
indicates that stats_.doc_char_quality is not initialized in control.cpp, Pass 
5:

BOOL8 good_quality_doc =
    ((page_res->rej_count / static_cast<float>(page_res->char_count)) <=
     quality_rej_pc) &&
    (stats_.doc_blob_quality / static_cast<float>(page_res->char_count) >=
     quality_blob_pc) &&
    (stats_.doc_outline_errs / static_cast<float>(page_res->char_count) <=
     quality_outline_pc) &&
    (stats_.doc_char_quality / static_cast<float>(page_res->char_count) >=
     quality_char_pc);

Can you please create test case to demonstrate "specific input conditions"?

That would be quite complicated, involving closed-source code, etc. Unless I'm 
not seeing another way to do this.

I can however make some experiments on my side.
