Size and alignment of a digit in an image for neural network training

Hi, I have been working on OCR using the Neural Network toolbox but I have a few fundamental doubts. Suppose I have the following images of digits:--

Since the digits are of different sizes, will it affect the neural network training and simulation? What are the parameters that a neural network uses to recognise images(like size, pixel values, shape, alignment, etc)? Please advise.

The input to the net from a single image is just a column vector of numbers of dimension I obtained by feature extraction. The feature extraction of an image of size r x c can be complicated or as simple as columnisation via
input = image(:);
size(input) = [ I 1 ] = [ r*c 1 ]
Hope this helps.
Thank you for formally accepting my answer

No. However, maybe one of the resident image experts will respond.
If there is no response, try making that another posted question.
