Decapod for RoBook Scanner


So far I am having a hardly thoughts on how I could clearly grasped designing stereo camera to capture imagery ;perhaps, via software or driver .Although the allotted span of time would take only just for (one) 1 semester. Apparently ,I have had this topic on the other part of my web blog that deal solely to "RoBook Scanner" and I knew that the topic would be too lengthy if I would not include or separated Decapod discussions here.

Decapod is an Opensource project ,it is a software tools used in a book scanning and was sponsored by Andrew W. Mellon Foundation ; the project is being maintained by volunteers and dedicated people around the globe-kudos to them! Imagine how much is the cost of a commercial book scanning software? oh huge price. Anyway ,never mind because Decapod is free to everybody who aspire the best of its suited applications . Recently,I have included this project in my techno-blog because I considered it as one of the best freeware you can ever have for free .It is a combination of a different software programs which were intended and incorporated for book digitization.; and to mention those share & freewares: gPhoto, OCROpus, Image editing/cropping , kPDF and the server hosting too.

So am beleiving this was really a real open source community project -indeed.

I want to share here the steps in installing Decapod in Fedora version #13(the most recent release?) and Ubunto version 10.04 .I will try to test steps and find out if it would really give me a lucky try.

The last things to say is to get it done(OK here we go!)
