Image processing/compression: Image processing involves that clean-up, cropping, straightening and compression of images. Bi-tonal TIFF Group 4 is still the most popular format for document image compression. However, the emergence of PDF and affordable color scanners have recently created some alternative imaging options.
TWAIN is a widely-used program that lets you scan an image (using a scanner ) directly into the application (such as PhotoShop) where you want to work with the image. Without TWAIN, you would have to close an application that was open, open a special application to receive the image, and then move the image to the application where you wanted to work with it.
Image Capture- Capture is the most basic building block of any imaging application. It is the process of converting hard copy paper documents to an electronic format. Typically this is done through the use of a scanner, which outputs a TIFF Group 4, JPEG, or a PDF formatted images.

Scanners – Scanners are used to convert paper documents to electronic images. There is a niche of scanners known as document scanners designed specifically for document imaging. They typically run faster and are slightly more expensive than flatbed scanners.
Compliance with regulations as gained a lot of attention in the imaging and enterprise content management (ECM) industries in the wake of scandals such as those involving Enron and Arthur Andersen. HIPAA, Sarbanes-Oxley, SEC 17a 3-4, the Patriot Act, and other regulations are often cited as drivers for imaging and ECM installations.
Every day more and more digital copiers are being scan-enabled. Scan-to-e-mail as fax replacement, was the initial killer app for scanning on copiers, but there is now a movement to transition them to more towards distributed capture devices for ECM/workflow applications.
