System information (version)
Detailed description

While running end_to_end_recognition.cpp, encountered error: "Default classifier file not found!" in ERClassifierNM1.

Steps to reproduce
sovrasov commented 7 years ago

@LABCAO please attach additional information. The sample end_to_end_recognition works only if startup folder contains trained_classifierNM1.xml and trained_classifierNM2.xml.

LABCAO commented 7 years ago

When the startup folder contains trained_classifierNM1.xml and trained_classifierNM2.xml, I would encounter this error:

A demo program of End-to-end Scene Text Detection and Recognition: Shows the use of the Tesseract OCR API with the Extremal Region Filter algorithm described in: Neumann L., Matas J.: Real-Time Scene Text Localization and Recognition, CVPR 2012
