LSTM recognize via TessBaseAPIRecognize() gives me the following performance numbers for the same bi-tonal image. The image is read and passed as a bitmap. These numbers are only for the TessBaseAPIRecognize() call portion of the process.
The question is this: should I have expected LSTM Only mode to be faster than Tesseract and Cube mode? This is an x64 Windows build of Tesseract with Leptonica 1.74.1. eng.traindata was used from the 4.0 download.
