From: parto.yazdani on 20 May 2009 14:54 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. DB |
