What is VRS?

VRS is image enhancement technology providing
The best quality images to your system
With minimum effort,
Representing all the content of the original
With the smallest file size possible.
VRS is an agent...
Watching the status of the scanner (out of paper,
paper jam, connection, etc.) and guiding the end
user to resolve any hardware issues.
Checking image quality continuously.
VRS is transparent to the application and drops
seamlessly in Kofax, ISIS, and TWAIN applications
without any integration effort.

4
Where is VRS located in the system ?
Scanner are connected with Adrenaline SCSI/Video
engines to a PC. Software VRS scanners also work
with Adaptec SCSI boards.
Scanners from BH, Canon, Epson, Fujitsu, Kodak,
Panasonic, Ricoh,
Before images are passed to the scan application,
the VRS agent verifies image quality and hardware
status. With Software VRS scanners image
enhancements are applied in the PC.
Hardware VRS scanners include a special VRS
scanner board performing VRS image quality
enhancement processing.
Scan Applications built with the Kofax
ImageControls toolkit, ISIS toolkit or TWAIN
compliant applications all work with VRS. VRS is
not limited to Kofax applications. It works with
virtually any Scan application.

When used with Software VRS, the scanner is
switched to grayscale scanning
Software VRS requires a gray scale image to
perform its automatic improvements.
No special hardware is required in the scanner
Scanner can be connected with USB, Firewire, or
SCSI

Scanning 101

What is
A true color image?
A 24-bit color image?
A grayscale image?
A 256-level gray image?
An 8-bit gray image?
A binary image?
A black and white image?
A single or 1-bit image?

9
Thresholding

What is Thresholding?
The conversion of a multi-bit grayscale image
into a black and white image is called
thresholding.

Why is it called Thresholding?

10
Basic Thresholding Compromising

This concept of simple thresholding results in a
compromise.
Whatever threshold level, there is always some
content sacrificed.
What we need is a thresholding technology that
preserves all the content of the original without
compromises. VRS is that Technology

11

VRS Key Benefit 1 !
VRS CAPTURES THE WIDEST SPECTRUM OF ORIGINALS
WITHOUT ANY ADJUSTMENTS, AND WITHOUT EVER
STOPPING THE SCANNER
16
VRS Key Benefit 2VRS Makes Scanning Easy
Production Scanning

Resume
Previous profession Burger Flipper at Bills
Burger Palace
Age 25
Interests Rockroll and the next party
Technology skills Playstation, GameBoy Advance
Motivation to produce quality images Zero!
Currently looking for a new job

Your document capture system should automate the
scanning process as much as possible !

17
VRS Key Benefit 2VRS Makes Scanning Easy Ad
hoc/Remote Scanning

The scanner operator is an office manager or
secretary, and scans only a few documents per day
There is virtually no scanning support
The office has invested in a low cost scanners
with little or no image processing functionality
Once the image is transmitted to headquarters,
rescanning becomes more difficult

18
Key Benefit 3VRS Produces Web-Ready Images
Color JPG - 150 DPI 212,992 bytes
200 dpi with regular scanner 135,087 bytes
200 dpi With VRS Only 47,578 bytes

VRS suppresses shaded and dark backgrounds. This
makes the text more readable and results in very
small file sizes perfect images to share over
the web.
With a 45 Kbit modem connection, it would take
about 40 seconds to download the 150 dpi color
image.
about 24 seconds to download the non VRS image.
about 9 seconds to download the VRS image !

19
How Well Will Group IV Compress These Images ?
Many transitions from black to white do not
compress well and even cause negative
compression.
Negative compression results in compressed
images that are larger than uncompressed images.
Large surfaces of white space compress well.
Large surfaces of black space compress well.

Background noise is the main cause of bad
compression
VRS suppresses background noise and therefore
image file size decreases

20
Key Benefit 4VRS Increases OCR Read Rate

Traditional deskew corrects the black white
image, resulting in jagged edges and artifacts.
VRS deskews the gray image first and then
converts it into a black white image.
VRS grayscale deskew produces crisper text.
Combined with VRS automatic text enhancement,
OCR forms processing systems produce up to 20
less questionable characters !

21
Key Benefit 4VRS Increases OCR Read Rate
Edge Fusion

VRS Fuses the Edges of Broken Characters
Therefore OCR Engines Can Read These Characters
Much More Accurately

22
Key Benefit 4VRS Increases OCR Read Rate

Using Adobe Acrobat and scanning in 200 dpi
The number of questionable words goes down by 60
or more !

Without VRS 2.0 27 questionable words
With VRS 2.0 9 questionable words
23
Exception Processing
24
Key Benefit 5VRS Avoids Exception Processing

VRS corrects 99 of the images automatically and
warns the user if an image is out of range.
Adjustments of images can be done without a
physical rescan of the original !
ROI is less than a year on average and in many
cases only a matter of a few months

The earlier you trap the problem the better !
25
VRS Improves Efficiency at Every Step
Scan/Import
Recognize
Verify/Rescan
Release/Retrieval

No pre-sorting by size or quality
Easier set-up
Easier to use
Fast recovery from paper jams and double feeds
Less training and support

high-volume scanners

Better OCR read rate for better forms processing
(edge fusion, smooth edges)
Better bar code reading
Better registration (auto-crop and deskew)

More readable images
All content captured
Few or no rescans
Avoids expensive exception processing

Faster release, thanks to small file sizes
Less storage space required
Faster retrieval times
All content readable

31
The VRS Interactive Interface

General Rule Work with the default settings,
dont change anything
By default VRS is tuned to handle the widest
variety of originals automatically
Only for exceptional and extremely difficult
originals, settings should be adjusted

Scan a Page
Right Click on the VRS Icon in the Windows Icon
Tray and Select Preview
The VRS viewer and Interactive Interface appears

32
What Is The Blue Rectangle?How Do You Change It?

The Blue rectangle indicates the acceptable
boundaries of an image.
If the brightness of an image falls outside these
boundaries, the interactive interface will appear
in Stop on Errors mode.

To change the size of the blue rectangle
Right Click on the VRS icon in the Windows icon
tray
Select Configure and change the Brightness Out of
Range value

33
VRS Tips and Tricks

What do the VRS sliders actually do?
Brightness Background and Fill Colors
Contrast Text and Lines (a.k.a. Edgy Objects)
Gamma Overall Scanner Calibration

34
Brightness Slider Background
High Brightness
Low Brightness
35
Contrast Slider Text, Lines and Edges

36
VRS Tips and TricksPatterned Background

In general, the background density is adjusted
with the brightness slider.
Sometimes what looks like a background color is
actually a pattern of lines, influenced by the
contrast slider.

Background consists of pattern of lines
37
The VRS Noise Filters

These filters should only be used with documents
of the same kind. Never use them on batches of
mixed originals!
Line Filter is excellent to make dot matrix text
bolder
Speckle Removal Filter removes noisy backgrounds

Scan a Page
Right Click on the VRS Icon in the Windows Icon
Tray and Select Preview
The VRS viewer and Interactive Interface appears
Select the Noise TAB

38
VRS Profiles

Use Profiles to load a set of VRS adjustments
with a single click
Avoid changing the Default Settings profile,
rather create new profiles

Scan a Page
Right Click on the VRS Icon in the Windows Icon
Tray and Select Preview
The VRS viewer and Interactive Interface appears
Select the Profiles Tab

39
VRS Profiles

Profiles can be selected directly from the
Windows Icon Tray
The Function key shortcuts only work when the
interactive interface is active

40
How do I reset VRS to its Default values ?

In general, never change the Default Profile.
Always make new profiles and keep the Default
Profile intact.
For VRS 3.x, re-install the software.
Or, install the Restore Default Values Utility

41
The VRS QC (Stop) Modes

On Errors (Default)
Opens the interactive interface when the
brightness of an image is out of range. Use this
mode when some of the originals are very dark.
First Page
Opens the interactive interface on the first page
of a batch and applies the settings of first page
to the rest of the documents in the batch. Use
this mode when switching batch jobs with very
different document types regularly.
Every Page
Opens the interactive for every scanned document.
Only used for extremely challenging originals
that require individual challenges
DISABLED (Advanced Users)
The interactive interface never shows up. Ideal
if VRS only adjusts a small amount and a small
percentage of images need to be adjusted.
Hardware Warnings (VRS 3.0 only)
Displays just the hardware warnings (Out of
Paper, Paper Jam, etc.) that may occur.
