Oh you gave so much info, thanks! My test exe file shows this version information: tesseract 5.0.0 leptonica-1.79.0 (Apr 14 2020, 06:42:43) [MSC v.1900 LIB Debug x86] libjpeg 9b : libpng 1.6.32 : libtiff 4.0.7 : zlib 1.2.11
Looks like I need to add (upgrade) the whole package понедельник, 13 апреля 2020 г., 21:02:42 UTC+3 пользователь zdenop написал: > > OS Name: Microsoft Windows 10 Pro > OS Version: 10.0.18362 N/A Build 18362 > System Model: Latitude E5570 > System Type: x64-based PC > Processor(s): 1 Processor(s) Installed. > [01]: Intel64 Family 6 Model 78 Stepping 3 > GenuineIntel ~2801 Mhz > > *tesseract -v* > tesseract 5.0.0-alpha-638-gef4f > leptonica-1.80.0 (Mar 12 2020, 12:47:16) [MSC v.1916 LIB Release x64] > libgif 5.1.2 : libjpeg 6b (libjpeg-turbo 2.0.2) : libpng 1.6.36 : > libtiff 4.1.0 : zlib 1.2.11 : libwebp 1.0.2 : libopenjp2 2.3.0 > Found AVX2 > Found AVX > Found FMA > Found SSE > Found libarchive 3.3.3 zlib/1.2.11 liblzma/5.2.4 libzstd/1.3.8 > > *-l eng:* > tessdata_best duration: 22.839419659999997 > tessdata_fast duration: 3.3998838399999984 > tessdata duration: 5.028869279999998 > > *-l eng+rus:* > tessdata_best duration: 42.03311656 > tessdata_fast duration: 4.122473539999999 > tessdata duration: 9.4696169 > > *-l eng+rus -c tessedit_do_invert=0* > tessdata_best duration: 33.66898392 > tessdata_fast duration: 1.7703644200000042 > tessdata duration: 6.849705899999998 > > tested with script: > > https://github.com/tesseract-ocr/tesseract/issues/263#issuecomment-536197289 > > I built tesseract with cmake and clang 10 with VS 2017 compatibility. > > Zdenko > > > po 13. 4. 2020 o 9:50 Ravil R <[email protected] <javascript:>> > napísal(a): > >> Sorry, I have just now seen your full answer with the questions, >> yesterday i've just got an email with the advice to go to the forum, that I >> did. >> Now the answers >> 1) I tested the latest 5.0.0-alpha build using all types of data files, >> modern: best, fast, normal and old: for 3.0 version >> 2) Yesterday I also tested 3.05 (with old tess data files) and 4.0 >> versions (both with old data file and modern "Fast" data files) >> 3) my PC is notebook i7-7700HQ, 32 GB, Windows 10, MS VC 2015.
