Blob Extraction Theory?

Postby emang » Tue Mar 10, 2009 10:02 am

Dear All,
I have already done my project in E-Comic reader for mobile handled using combination of filter and especially blob extraction object from AForge. Now I want to finish my report, so I am looking for technically (theoretically) documentation about blob filter in Aforge. Is it using Connected component labeling (CCL) method? Whose ccl method was using in Aforge? Someone please provide me the link or web documentation about ccl method using in Aforge. Thank you for your help
regards

Hello,

Yes, it is just connected components labelling. The initial idea was taken from here. But as you can see, there is just color labelling. So the idea was generalized and BlobCounter has appeared. This means that the labelling algorithm and code were designed for AForge.NET framework from scratch, just with that idea. There are no other references were used.
With best regards,
Andrew

Thanks Andrew for your quick response. Blobcounter was so useful in my project so thank for AForge and all people behind it especially for you. I start my project using IPLab then I modify it. Since my current work using Windows app, now I want to finishing my project as a mobile app. Do aforge.net library work/support for mobile app? sorry for asking fool question because i never try mobile app before, especially using .net ;)
thanks before

best regards

Hello,

No, at this point AForge.NET Framework is not provided for .NET Compact Framework used on mobile devices. And it will not be so simple, since CF .NET has limited supports of image formats. Many of the formats used in AForge.NET Framework are not supported actually by CF.NET.
With best regards,
Andrew

Just to clarify the idea, look at the list of formats supported by CF.NET(look for mobile icon near to formats). Only 4 formats are support.

AForge.Imaging library uses Format8bppIndexed format heavily, which is useful for grayscale images.
With best regards,
Andrew
