2016-03-12 08:02:55 -0600 | commented question | How to use KNearest in java? As you can see java documentation doesn't say much. However I have to detect digits, I can't use third part libraries so I can't use OCR like tesseract or similar. I have 500 image samples for each digit (size 20x20) and I should want to use them to train my KNearest object. I have to use the method: 1) But in which format should I put my samples Mat? And what int layout stay for? Then if I understand I have to use the method: 2) In this function my Mat samples is the Mat responses of train function, right? But in which format will be my Mat results? Thanks in advance for your answers and sorry for my English^^ |
