Product Overview VRS makes high-volume scanning easier and more cost-effective than ever. With automatic detection of poor image quality, VRS performs automatic image enhancements that greatly reduce recognition errors. To ensure that every scanned image can meet your standards, VRS provides an interactive settings control that eliminates the guesswork with easy, real-time image correction. Other features include the ability to scan batches that consist of multiple document sizes or varying degrees of quality, as well as the ability to automatically assign contrast and brightness settings that are optimal for your document type. If specified, VRS can even remove color that may interfere with the data you are collecting. VRS will also detect paper jams, bent corners, and equipment conflicts. It is no longer necessary to pre-sort mixed batches, and in addition to the time savings, post-processing accuracy is increased and storage requirements are reduced. For batch scans in which Optical Character Recognition (OCR) precision is crucial, as it is for database-bound information, low-contrast documents traditionally pose significant problems. With VRS, you can enable "Intelligent Contrast / Brightness Adjustment" and process the batch with confidence, knowing that every low-contrast image will be adjusted automatically to the acceptable level of quality required for OCR. In addition to Intelligent Contrast / Brightness Adjustment, VRS offers a range of features to help you ensure the highest level of quality for every scanned image: · · · · · · · Automatic Deskew Correction Image Cropping Accelerated Scanning Despeckling Gamma Correction Character Smoothing Character Dilation/Erosion Kofax Image Products 1 VRS Getting Started Guide VRS Product Package Your VRS product package includes the following items: · VRS installation CD · Scanner cable · VirtualReScan Getting Started Guide System Requirements Be sure that your PC and scanner meet the following requirements: PC · Pentium II class PC with a 200 Mhz processor, or greater Pentium II class PC with a 400 Mhz or greater (grayscale scanning) · 64 Mbytes RAM 128 Mbytes RAM (grayscale scanning) · Windows 95 or Windows NT 4.0 with 32-bit support · Hard drive with 200 Mbytes free disk space · Monitor resolution: 800 x 600 minimum; 1024 x 768 recommended · Adrenaline 850v Hardware Accelerator (sold separately) Scanner · Ricoh Model IS450DE/V 2 Kofax Image Products VRS Getting Started Guide Installation This section explains how to install the hardware and software required to run VRS.
