According to new question, here is the answer: StreamWriter outputFileTwoo = new StreamWriter(resultatsTwoo); List <string> firstListThatIcantRevealItName= new List<string>(); List <string> secondListThatIcantRevealItName= new List<string>(); firstListThatIcantRevealItName=System.IO.File.ReadAllLines(@”C:\Users\me\Desktop\blabla.txt”).ToList(); secondListThatIcantRevealItName=System.IO.File.ReadAllLines(@”C:\Users\me\Desktop\potto.txt”).ToList(); using(StreamWriter outputFileOne = new StreamWriter(resultatsOne)) { foreach (string trade in secondListThatIcantRevealItName) { endofFile++; if (!secondListThatIcantRevealItName.Contains(trade)) { outputFileOne.WriteLine(“Trade number : ” + trade + ” exist in first list but not … Read more
As a basic technique, use binarization and connected component analysis. This will give you “blobs” corresponding to the individual characters and you can get their bounding boxes. You will face extra difficulties: some characters can touch and form a single blob. You will need some detection logics to split them, for instance based on size … Read more
