Deskew an image,


Despeckle an image,

Automatic Image Repair

  • Auto-rotate image: 90 °, 180 ° or 270 °
  • Auto-deskew image based on content: +/- 45°
  • De-speckle: remove black and/or white noise

  • Remove borders. Deskew and crop based on black borders
  • Remove punch holes

Image Analysis and Processing Tools

  • Segmentation analysis. Identify image objects
  • Identify vertical and horizontal lines
  • Measure image skew angle and rotation
  • Measure image margins
  • Measure pixel content and histograms
  • Image scaling with smoothing
  • Morphological filters: fattening, trimming

Image source

Fully automated images processing addresses the most pressing needs of high volume imaging systems. VeryPDF Image Processing SDK is a result of VeryPDF's 20 years experience to address requirements of thousands production installations. This resulted in achieving:

Improved image visual quality

Automatic rotation, deskewing, noise reduction brings visual quality of scanned or faxed image close to the printed original. Smoothly scale images to high quality thumbnails for Web presentation. Convert low quality standard faxed images to fine mode

Reduced image file size

Removing many image artifacts, cleaning noise, smoothing characters, straightening lines can significantly reduced size of compressed image file. Scale images to reduce image size. Convert color grayscale to high quality bitonal. Result is significant reduction in storage space requirements and much improved speed of image transmission over the Internet.

Improved OCR recognition rate and performance

Automatically and quickly clean images prior to OCR: deskew, auto-rotate, clean noise, remove lines. Removing of image artifacts that impair OCR process translates to higher recognition rate as well as recognition speed.

Development of specialized imaging applications

Document segmentation, lines identification and other image analysis tools are core of form processing application. Low level image processing tools like morphological, filters, binarization, scaling, etc. used to build specialized document processing tools.
