Adjusting Image Tones to Improve OCR Results

Posted on January 9, 2019 by Nick Villalobos

Tonal range is an important attribute of an image, especially photographs, when trying to improve OCR results. Tonal range is the range of tones between the lightest and darkest areas of an image and is also known as contrast. An image with a wide range has both very dark (black) and very light (white) elements. An image with a narrow range is more limited in its tonal scope, which is usually in the mid-ranges (varying shades of grays).

Regardless of your targeted platform and environment, be it Winforms and C#, or WPF or UWP, Visual Studio is the IDE of choice.

Correct Photos of Documents – Two- and Three-dimensional Skew

Posted on October 15, 2018 by Gabriel Smith

As I mentioned in my previous post, Correct Photos of Documents – Ambient Lighting, most images of documents suffer from skew. There are two types of skew: two-dimensional and three-dimensional.

Text is typically parallel to the top and bottom of the paper. Simply put, two-dimensional skew is the angle of the text when compared to the top or bottom edge of the image. This type of skewing can occur in photos of documents as well as document images produced by a scanner. While it is relatively easy to correct with a simple rotate, determining the angle of rotation can be tricky. Fortunately, LEADTOOLS includes a DeskewCommand class that can determine the angle of skew.
