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.

If you've been keeping up with us, you are already aware of our recent update to our Android, iOS, and OS X development libraries (if not, go read it!). Shortly after that release, our developers have been rolling out updates to all of our mobile demo apps available on the App Store, Google Play, and Windows Store.

In addition to updating our existing demos, we plan on adding new demos for credit card and passport recognition, so keep a close eye on that page if those features are of particular interest to you. If you can't wait (and we don't blame you), the source code for those demos ships with the main evaluation for each platform.

A few months back, we did a white paper on Check Processing. Today, we published a new Check Processing Video showing off this exciting and powerful technology. In addition to the Check Processing SDK, it also shows off the Perspective Deskew function which will correct images taken ad odd angles from mobile devices.

We hope you enjoy the video. We plan on keeping them coming regularly, so if there are any specific LEADTOOLS features you want to see highlighted on our YouTube channel, please let us know!

As part of the LEAD Technologies 25th anniversary, we are creating 25 projects in 25 days to celebrate LEAD's depth of features and ease of use. Today's project comes from Joe.

What is Does

This Objective-C project will process images using LEADTOOLS Version 18.
