They're not square.

From: Samiov on 14 May 2010 03:36 Good morning ImageAnalyst, Hope you understood what I said.. At the end, the image must look like a checker board..if the square's tile is white, then it means that the vertical yarn is in high position and if it's black it's in low position. Hope there's a method to detect the colour of each tile (that now each one has a unique gray colour) and to put it in a new image composed of the same number of tiles but these tiles have a uniform size (100 x 100 for example). It will be great if we reach this step and finally finish the work.
