imaging SDKs that accelerate development
ScanFix Xpress

superior scanned image cleanup SDK

Color, grayscale, and bitonal image cleanup
Improve content recognition accuracy
Create smaller compressed files

.NET 32/64-bit | ActiveX 32-bit

Color Detect
& Auto Binarize

Color Detect:
  • Allows for mixed document color scanning applications containing both color and black and white documents
  • Analyzes 24-bit images looking for significant amounts of saturated color data
  • Recommends if color images can safely be converted to bitonal

Auto Binarize:
  • Provides improved automatic conversion of 8-bit and 24-bit grayscale and color images to black and white
  • Automatic mode analyzes images to determine best binarization methods and settings
  • Offers user-configurable options to fine tune results

Page Enhancement

Color Deskew:
  • Automatically straightens crooked 1, 8, and 24-bit images
  • Reports correction angle in a fraction of a second, based on image contents, not document perimeter or border
  • Offers user configurable High Quality vs. High Speed setting
Auto Border Crop:
  • Automatically converts dark borders to white or removes border completely on 1, 8, and 24-bit images
  • Reduces image file size (physical dimensions and compressed file size)
  • Automates border crop (user configurable to report or automatically correct)
  • Use on microfilm/microfiche scans or small document images
Blank Page / Blank Rectangle Detection:
  • Identifies and reports blank pages, or blank areas of interest, on 1, 8, and 24-bit images
  • Configures settings to accommodate bleed-through or noisy images (i.e. ignore hole punches)
  • Increases storage capacity by eliminating blank pages
Image Registration:
  • Registers the image "contents" to be a specified distance from the top and/or left side of the page
  • Applies to 1, 8, and 24-bit images
  • Use with zonal recognition to establish the position of the text


Adjust Brightness
& Contrast

  • Analyzes and corrects the brightness and contrast of 8-bit grayscale and 24-bit color document
  • Corrects the image using either a globally applied brightness remapping or adaptive remapping
Color Removal

Color Drop:
  • Locates specified RGB colors in 24-bit images and drops those colors to white or a specified color
  • Identifies pixels to change based on proximity to user-specified color values
  • Provides very precise control over color manipulation
  • Supports color conversion and color blending to target color

Virtual Bulb ®:
  • Performs software-based HSV color dropout on 24-bit images, emulating a hardware-based dropout scanner through much more powerful and flexible technology
  • Allows multiple hues and ranges within hues to be dropped to white and adjacent colors to fade into shades of gray
  • Compensates for variations in color saturation and brightness caused by printing environments


Character Enhancement

Character Completion & Smoothing:
  • Repairs, smoothes, and thickens incomplete characters on 1-bit images
  • Performs well on poor dot matrix text
  • Smoothes ragged edges on letters
Dilate and Erode:
  • Thickens or thins objects in 1, 8, and 24-bit images
  • Apply horizontal, vertical, or diagonal adjustments
  • Increases recognition accuracy in lightly printed or very thick text


Hole Punch & Line Removal

Hole Punch & Blob Removal:
  • Removes hole punches and larger areas of black on 1-bit images
  • Enables user configurable threshold settings
Line Removal:
  • Automatically removes solid or broken lines (horizontal and vertical) from scanned forms and documents on 1-bit images
  • Automatically repairs text that intersects with lines (fill broken characters), essential for accurate OCR / ICR and forms processing
Comb Removal (commonly used in ICR forms):
  • Automatically removes data entry combs from forms in 1-bit images
  • Automatically repairs text that intersects with lines (fill broken characters), essential for accurate ICR

Included Components

  • ScanFix ® Xpress for image cleanup
  • ImagXpress ® for image compression/decompression and display
  • NotateXpress™ for adding image annotations
  • PrintPRO™ for printing
  • ThumbnailXpress™ to view thumbnail images
  • TwainPRO™ to acquire images from TWAIN devices
Image Detergent ®
& Filters

Image Detergent ®:
  • Cleans up noise and variations in specified colors in 24-bit color images
  • Flattens each color region to a specified color by adjusting each color region to its center point
  • Offers an automatic mode to clean dominant colors or can specify color list
  • Removes JPEG compression artifacts commonly found around characters in scanned color documents

Filters:
  • Applies various filter operations to 8-bit and 24-bit images
  • Offers a variety of options including smoothing filters (Gaussian, median, average), sharpening filters (unsharp mask), morphological filters (dilate, erode, open, close), edge detection filters (Laplacian, Prewitt), and provision for user defined convolution filters


Background Cleanup

Noise Removal:
  • Removes random specks or noise on 1-bit images
  • Performs speck removal based on user-specified speck size
Dot Shading Removal:
  • Automatically removes dot shading for improved OCR accuracy on 1-bit images
  • Removes scanner noise caused by colored backgrounds
  • Significantly reduces compressed file sizes without destroying text

Text Correction

Auto Inverse Text Correction:
  • Detects and automatically converts inverted text zones on 1-bit images
  • Changes white-on-black text to normal black-on-white

Auto Negate:
  • Analyzes 1, 8, and 24 bit images to determine if they are inverted (light text on dark background, dark text on light background)
  • Offers automated correction to reverse colors, if needed (user configurable to report or automatically correct)


Additional Image Processing

  • Performs Flip, Mirror, Rescale, Rotate, and Shear on 1, 8, and 24-bit images
  • Offers Smooth-Zoom to double the width and height of a 1-bit image and smooth objects for better recognition (ideal for improving barcode and OCR results)


Sub-Image Processing

  • Applies to 1, 8, and 24-bit images
  • Separates out an area, from the original document image, prior to image processing
  • Speeds up processing and outputs only the smaller area of interest
