Hello all,
I' m Hendy. I'm newbie in neural networks I was trying to develop some ocr project and implement backpropagation method. I have been already sets the train function, but I still confusing about using the output result. How can I use the output to recognize some character? Do I need to make comparison to the binary of some character? Here is the following steps that I have been do:
TRAINNING
1. Converting text input to image
2. Normalization character image size into 10x12 matrix
3. using backpropagation.
4. get the weight and saved it.
RECOGNITION
1. Preprocessing input image(scanned text document)
2. Character image segmentation
3. Character image size normalization without thinning the character(I don't use it)
4. Convert the segmented and normalized character image into binary and set it into array (10x12 matrix).
5. backpropagation (forward propagation)
6. get the output

I have no idea to use the output to recognizing character?
Sorry about my bad english :).

Thanks everybody!
