Hi,
I have a problem and I`ll be really appreciated if you can solve it.
My project is to read 2 Jpeg files (hand writings) and compare them by
using correlation coefficient.
I found out how to read a jpeg file and also I found out that I need
to convert my images to arrays to wire them to correlation block But I
couldn`t find how to convert them to arrays.
Thank you so much
best regards
Parto Yazdani

I did this years ago for greyscale images by converting jpg to .pgm (portable gray map) files. The bitmap was dumped to a text file and imported into Excel.
Some graphics programs will save the pgm as a continuous line of numerical values, ready to import. Most save it as lines of ten numbers, which has to be further processed by a custom program in order to be imported into Excel. The ten-number lines have to be converted to n-number lines.
