| 2015-12-13 22:57:07 -0600 | asked a question | Detect 7 Segment fault on a LCD display Hello there, I have to develop an algorithm to detect faults on a LCD display with 7 segment characters. I started to develop the algorithm , but all I did til now was finding the Region of Interest (ROI) , the display. This is a screenshot of the algorithm execution:
Thera are 4 displays in the picture, and I find the regions where they are positioned. The display will be at the state with all the segments turned on, so it should be easy to detect any fault on them. Now I have to finally execute an algorithm to find faults on the segments, but I'm not sure how am I suppose to do it. I was thinking in using SVM and machine learning for detecting the characters, but I wonder if this is the best way of doing this, as I don't need an OCR for reading each character, I just have to know if all the segments are on or not. Would you guys have any advice in how should I make this application? Thank you very much. Renan Fonteles. |
