Book Restorer™ includes numerous image restoration processes which are continuously accessible from anywhere in the application.

You can:

• apply them to your images, either immediately or in batch mode using Automaton or Watcher,
• organize a chain of several restoration functions into scripts and apply them immediately or in batch mode

Numerous dialog boxes offer precise parameter set-up allowing you to customize restoration according to your needs.

The power of the image restoration processes and their ease of implementation ensure you user-friendliness and increased productivity.

Advanced Geometrical Processes

• Geometrical correction corrects distortions caused by scanning on a vertical scanner (book curvature) or the presence of crumpled pages.
• Deskew corrects for the scan angle.

Rendering Enhancement

• Binarization converts all greyscale or color documents into black and white images.
• 1D lighting correction corrects light variation produced by surface relief or book curvature. When you scan a thick book, the shadow of the binding will appear on the image. This module allows you to obtain light uniformity to eliminate such shadows, whether vertical or horizontal.
• 2D lighting correction deletes variations in brightness sometimes introduced during scanning.
• Finger Masking allows you to manipulate more easily your documents during the scanning operation since it detects and automatically masks the images of the operator’s fingers on the side margins. This process masks the finger images by substituting a homogeneous background. You can thus hold the book open with your fingers or tools on both side margins during the scanning operation.

Page Layout Helper

• Area detection lets you manually or automatically isolate the graphics components and text fields on your page.
• Crop: this module offers three different image cropping possibilities: division of an image into several sections (horizontal or vertical), manual crop (definition of a cropping frame by the operator), automatic crop (automatic search of the main information in an image).

Other standard processes

• Adjustment of histogram redistributes the colors over all possible values.
• Color conversion allows an image to be changed from one colorimetric mode to another.
• Colorimetric curves can be used to change the color palette.
• Despeckle corrects the effects of binarization or scanning interference.
• Filter applies special effects to an image (e.g.: add blur, sharpen, thicken...).
• Hue, Saturation, Lightness (HSL model) allows you to adjust the colorimetric components of the image.
• ICC Profile allows you to check the consistency between the various peripherals involved in a digital image processing chain.
• Light and contrast allows the light of an image to be lightened or darkened, and the difference between the darkest and lightest color to be modulated.
• Negative allows you to invert the colors of an image.
• OCR: If OCR software is available on your PC, the OCR module allows you to launch it from Book Restorer™.
• Photoshop® Script: if Adobe Photoshop® software is available on your PC, you can use Photoshop® scripts from Book Restorer™.
• Polarity detection allows you to detect automatically if an image is positive or negative and, if it is negative, its polarity will be inverted.
• Resize: image resizing modifies the resolution, size or proportions of an image.
• Transformation can be used to make rotations or simple symmetrical manipulations.
