Hello! I am new to Mathematica and I have this image: http://i.stack.imgur.com/Ta5wf.png Is it possible to let Mathematica separate the image into one small one for each character? >From my cs classes I remember that VoronoiDiagrams might be a way to calculate the grid between the characters. Alas, VoronoiDiagram[] only accepts a list of points, not an image. Any ideas? Cheers, Sven Hi, Sven, I do not know much about Voroni diagrams. However, this im is your initial image. I went to the web page that you gave above, and copy= -pasted the image into Mathematica wrapped by Image[]. Then this ip = ImagePartition[im, {Scaled[1/5], Scaled[1/4]}] yields a list containing the letters, each letter is an image. You may addr= ess individual terms of this list by evaluating the expressions like this: ip[[1, 4]] (* This gives D *) ip[[3, 5]] (* This gives O *) one of the numbers gives the line, another gives the column.
