Excerpt from AIIM’s new Capture Software Product Study on Standard Output Image Formats… As bandwidths were limited when the imaging and document management industry began, the industry adopted 200 dots-per-inch TIFF Group 4 compressed black and white images as their standard (which created a roughly 75K KB image for a standard page of text). A secondary advantage to the TIFF group 4 format was that it is a loss-less compression standard—i.e., no image data is removed during the compression. Each vendor then added some specific headers which made their formats unique. Third-party capture vendors therefore had to create “formatters” or “release scripts” in order to create an image that would seamlessly import into the document management systems. In the photographic and consumer world, a lossy standard named JPEG became ubiquitous and is used exclusively in mobile phone captured images. The accuracy of OCR and other recognition technologies from a JPEG compressed format depends not only on resolution but also on the amount of loss that was taken when the image was compressed. Usually compression can be as much as 80% without much loss, but this very much dependent on the complexity (busyness) of the images since JPEG encodes areas of…
