Boost Work Efficiency Through Superior Image Processing

Grooper enhances document images displayed to users throughout your workflow, improves OCR, and provides crisp versions for permanent archival.

It also analyzes page structure to assist with automated decision making downstream.

How Does Image Processing Improve OCR?

Good OCR (optical character recognition) starts with images free of non-text artifacts. Grooper has dozens of features that remove everything that isn’t text to ensure you get distraction-free OCR:

Now let’s look at a few examples to show in detail what Grooper’s image processing is doing:

Safe and Clean Halftone Removal

Dithering and other halftone patterns are a direct result of legacy document imaging platforms poorly converting color images to black and white.

These artifacts must be eliminated to prevent massive errors in OCR results, particularly with punctuation like periods and commas.

Before Halftone Removal:

Halftone artifacts completely surround text we’d like to capture. OCR stands very little chance at seeing these characters.

After Halftone Removal:


Grooper recognizes dithered patterns and safely removes them without eliminating legitimate punctuation that is close to letters on the page.

Seriously Brilliant Border Removal

Borders have commonly been very tricky to remove when the black region doesn’t extend all the way to the edge of the page.

Grooper understands how to address a variety of uncommon border scenarios to cleanly remove them.

Photoshop-Like Inpainting

You work with full-color documents every day. So why shouldn’t your digital image processing do the same, no matter the image format you are using?

This is no problem for Grooper. It’s object removal and editing breaks out of the realm of black-and-white processing with full color recognition and editing.

Use this feature to digitally restore damaged or unknown parts of an image using information from nearby pixels.

Pixel-Perfect Line Detection & Removal

For humans, lines are needed to provide visual cues that increase readability. Lines of all sizes are common and frequent in standardized forms, table structures, and pages with “fill-in-the-blank” comb boxes.

However, these lines, particularly the short, vertical ones, are commonly and mistakenly read by OCR engines as letters or numbers.

But Grooper computer vision can erase these lines with ease…

  • Line dropout is performed using a very precise, pixel-by-pixel mask of lines rather than a generic point-to-point/thickness approach. This method leaves no edge artifacts behind, providing a cleaner OCR image.
  • This approach works well with very short lines, even the lines that are smaller than many of the letters on your pages.
  • Grooper knows the difference between lines that should be removed and text that shouldn’t be removed like “L, l, I, and 1”.
  • Any letters or numbers that happen to be connected to lines are found and saved, in order to keep valuable data for your OCR process.
