Image enhancement : median filtering

Hi folks,

We continue the series of explanations on image enhancement techniques meant for our general public and this week we are going to give you some additional info about median filtering.

Images quite often contain artifacts known as “noise”.
“Noise” means, of course, un-wanted sounds occuring in an audition context but the term quickly expanded to other domains, designating the presence of un-wanted randomly disseminated artifacts within any given context.
In imaging domain, for instance, one of the frequently occuring noise-types is called “salt and pepper noise”.
Quite an intuitive name, as images affected by this type of noise look like as if salt and pepper particles were poured over “the clear” image (bright pixels on darker areas and dark pixels on brighter areas of the image).
The usual causes for this issue are hardware related (analog-to-digital conversion, bit errors in transmissions, etc.).

Which brings us to the median filtering : one of the most effective method to remove such noise from images is to apply the median filter.
This is not the place to go deeper into technical details, but for those of you wishing to find out more about this subject, you can read the Wikipedia article or even study this academic material.

Median filtering is yet another must-have feature because not only it renders the image/text documents more comprehensible but it also enhances OCR results if applied prior to OCR submission (because it removes noise but preserves edges).

All our products, SDKs (GdPicture.NET) and general public products (PaperScan and PaperLight BETA) provide the median filtering feature.

Cheers,

Bogdan

Deskew/Autodeskew : what’s that ?

Hi folks,

This week we thought about offering to our general public some explanations about deskew/autodeskew, mainly to answer two questions : what’s that and why is it important to have ?

Skew is an artifact that might appear during document scaning process and it consists of getting the document’s text/images be rotated at a slight angle.
It can have various causes but the most common is paper getting misplaced during scan.
Therefore, deskew is the process of detecting and fixing this issue on scanned files (ie, bitmap) so deskewed images will have the text/images correctly and horizontally alligned.

And why is this important ?
Well, a first benefit will be that you don’t have to scan in again the skewed documents.
Instead of the mechanical and time consuming actions that re-scan involves, everything is done automatically and efficiently by the software providing deskew feature.

But there is yet another important benefit of deskewing : for those who need to OCR the scanned documents, deskew is an important correction to do before submiting to OCR process.
Deskew increases the rate of character recognition accuracy because alligned text is much closer to what the OCR software is supposed to encounter when performing image analysis.

All our products, SDKs (GdPicture.NET) and general public products (PaperScan and PaperLight BETA) provides the autodeskew feature as it is a must-have for any professional document imaging software.

Cheers,

Bogdan
