Delicious Library pioneered using a webcam to scan barcodes, and is still the only program that works with built-in iSights — these do not have the ability to focus. We had to write a new algorithm, using hard math and research papers and stuff, to do “image deconvolution” where we actually use the vector processor to re-focus the out-of-focus image, like in the movies or CSI, except for real. (If you’re familiar with Photoshop, their “unsharp mask” is a primitive deconvolution filter, but suffers from artifacts that make it unusable for barcode scanning.)— Delicious Monster (http://www.delicious-monster.com/), in the “From Your Shelf to Your Screen” section, retrieved 6:20 p.m., June 16th, 2008
