This however will generate a lot of false positives. This is a sub-image search and a number of methods exist, though "compare" is probably the simplest. One method is to make a small image of the punch hole, and search the image for the location of the punch hole. Those locations will give you the coordinates needed to do the distortion. The tricky part is to find the location of the punch hole holes. The tricky part is not distorting the image to align them. You do not need a 'reference' image, though it could be some help. Re-positioning the pegbar to the same position is pretty much impossible so if I need to do a fix on paper and re-scan a drawing, the entire scene needs to be re-scanned-Ugh! Going paperless and drawing on a Wacom tablet or Cintiq isn't an option. I'm currently solving this problem by temporarily taping a metal pegbar directly to the scanner's glass platen but the pegbar cannot stay attached permanently because the scanner is used for other purposes. Note that I'm using standard 1/4 inch 3-hole punched paper but the script should also be able to handle acme punched paper. I made these scans with the scanner top open so the hole punches would show up better and so the built in automatic cropping wouldn't cut off any of the image. However, I'm not very skilled at coding and have no idea where to begin. It seems to me that it would be trivial to write a script that would line up a batch of scans to a reference image of a blank sheet of paper with just the hole punches. Although it is written in Java, it doesn't work at all on Linux. I tried converting the scans with imagemagick but the program seems to work only on files captured on a Macintosh via TWAIN in Photoshop. In addition, there is a free program specifically for this purpose called ScanFix - but it can only use TIFF files with Macintosh byte order-my scanner writes to a memory card in JPEG format. There are several commercial animation packages that can do this including Toon Boom, TV Paint, DigiCel Flipbook, Animo and probably a few others. This helps you experiment and learn timing better than any other app.I'm doing some hand drawn 2D paper animation and would like to line up my scanned images using the hole punches. This lets you see the results immediately. But FlipBook lets you fix the timing while the scene. Changing the spacing requires new drawings. Timing and spacing are a very important part making animation look smooth and natural. This allows animators to work in a way that is still familiar and comfortable. Many studios use DigiCel FlipBook for their pencil tests because it most closely simulates the traditional method. Now days we can shoot the drawings with a webcam or draw them right into the computer with a graphics tablet or on the computers display. This helps you make sure the movements and expressions tell the story and convey the desired emotions effectively. Pencil Tests also help you fine-tune the performance of the characters. That way you can find and correct problems like timing errors, awkward movements, or inconsistencies in character shape, size and animation. You need to review and correct your drawings before you spend the time to ink and paint them. Then they would shoot those drawings on film and develop them before they could be seen. Traditionally animators would create rough sketches or drawings with a pencil on paper. Pencil Test is a traditional technique used to test the timing and spacing of an animated sequence among other things.
