Everybody has a smartphone in their pocket. With today's technology there is no reason to carry around a smartphone, business card scanner and a receipt scanner; just use the camera on your phone!

Scan Anything, Anywhere, Any Time
Scan anything, anywhere, any time. That is the dream for many people, and today's technology is making that a reality. Using a camera such as those on smartphones to capture information provides flexibility and can do things that a traditional scanner cannot. With the right image processing tools, a camera can capture receipts, documents, business cards, whiteboards, large format drawings, periodical pages and of course snapshots of business associates and friends with extremely high quality.

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 Justin.

What it Does

This ASP.NET C# application will display a thumbnail image gallery using LEADTOOLS Version 19.

Visual Studio Magazine announced the winners of its 22nd annual Reader's Choice Awards. The 2015 winners were chosen by the readers of Visual Studio Magazine and honor the best Visual Studio-related tools and services in 31 categories.

LEAD Technologies is proud to be awarded Gold in two categories and Bronze in a third.

Recently, a customer needed to find the differences between two images. More specifically the customer needed to find what changed between the two images and crop to leave only the change. From there, the LEADTOOLS OCR engine converted the cropped image to text to create a screen reader for visually impaired users. Additionally, animation and compression algorithms use similar techniques to improve performance and efficiency.

Support quickly responded to the customer with a C# console application example that finds the bounding rectangle of the differences and then crops the image.

Blank page detection is an important step in most document imaging workflows. For example, it can be used to help end-users make sure they have their paper facing the correct way and inform them when they've done something wrong. For a more automated solution, blank pages can be removed to save on disk space and bandwidth.

However, the difficulty with blank page detection is that it can be a bit subjective. Humans can quickly perceive a blank page because we see that the page doesn't have any text on it. But what does a computer do with a text-less page with lines, noise, borders and the like?
