In order to tackle hi-res graphics adventure game, SmartAdventurer needs to be able to recognize text displayed on a graphics screen. This is the first test after I integrated the program with OpenCV and Tesseract.

I'm surprised to find out that Tesseract does not consistently provide the same output given the same image. You may notice that the recognized text shown in the left pane changes a little bit before it "stabilizes". Also, the text recognition is not very accurate because the text displayed in the Apple ][ hi-res graphics mode often have strong green and purple tint. I probably need to re-train Tesseract to improve its accuracy.
