Hi Martin, Some things indeed can be done to improve results for the upper word.
- Source image (inet009.jpg) - Upscale by 5x. This is required since your upper word has too small characters. (inet009_rs.jpg) - Crop out your upper word - you need to help Tess with layout analysis (inet009_rs_cr.jpg) - Threshold - you need to help Tess with binarization >convert inet009_rs_cr.jpg -threshold 45% inet009_rs_cr_ts.jpg (inet009_rs_cr_ts.jpg) - Call Tess. I don't know if Spanish traineddata contains two-dotted "e" but French surely do. Used Tess compiled from sources as of 20150203. Perfect OCR result. >tesseract inet009_rs_cr_ts.jpg inet009_rs_cr_ts.jpg -l fra (inet009_rs_cr_ts.jpg.txt) The lower word just being cropped out leads to normal recognition.
