When performing OCR, some of the Tesseract settings perform better than others on a variety of different workloads, but they mostly take ~negligible incremental time to run compared to the overhead of running the ImageMagick filters. After this commit, we try using all three of the current Tesseract models (classic, LSTM, and classic+LSTM) to generate output text. This fixes chromium-90's tests at release-20.09, and should make cases where you're looking for *specific* text better, with the tradeoff of running Tesseract multiple times. To make it sensible to cherrypick this into release-20.09, this doesn't change the existing API surface for the test driver. In particular, get_screen_text continues to have the existing behaviour. |
