Hi! I have some problems with the outline approximation. It seems that when i try to recognize a single character with a small stroke above it(like on picture 2), the outline approximation doesn't work anymore. If I left out the stroke(picture 1), the outline seems to be "stable". I made two gifs to demonstrate what i mean. The gif shoes multipel recognitions of the same picture. The green lines are the inner/outer-outlines and the purble square is the boundingbox. (Please ignore the green circle on picture one, its just the recognition output.)
Approximation of the outline happens in polyaprx.cpp Unfortunately my understanding of the algorithm is no deep enough to totaly understand whats going on and find the error. It seems that only the y coordinates are biased by the additional height from the little stroke. Could someone point me into the right direction in how to solve this or maybe introduce me to an other outline approximation algorithm? <https://lh4.googleusercontent.com/-Tu1_KASjvZw/UWzpD2Y4GeI/AAAAAAAACC0/YAdTTlVXoGA/s1600/stable_outline.gif> <https://lh3.googleusercontent.com/-P44tG41JZdY/UWzoVLNGS9I/AAAAAAAACCk/JDngDC4O_UE/s1600/outline_unstable.gif> -- -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
