The Decapod 0.4 release builds upon the 0.3 release by improving connectivity with supported cameras, bug fixing, and a number of back-end enhancements. New to this release is the "Camera Calibration" screen which guides the user in setting up cameras in an independent left and right camera configuration.
On a properly configured machine, Decapod 0.4 will be able to:
Configure the camera order and image rotation when capturing using independent left and right cameras.
Capture images from a pair of supported cameras. (See Decapod FAQ for supported cameras).
Do some basic remastering of the captured images.
Export the collected images as an image-based PDF document.
By the end of the project, you should be able to:
Perform stereo dewarping on images, effectively flattening book pages.
Specify content bounding boxes to eliminate unwanted clutter from book pages.
Export to PDF with support for font generation and searchable / OCR text.
Save a Decapod book as a set of images, or archive the book to be processed on a different system.
Import images from disk, USB drive, or other media (there will be some caveats to this feature).
Save and resume multiple books.
More advanced book remastering tools.
Batch / deferred processing and exporting.
Being an early release, you should expect some lacking functionality, quirks, bugs, and other oddities.
While some of these issues may already be known and documented, some may not. Your feedback in using and testing this release will help us make improvements in future releases!

Limitations and Known Issues
It is strongly recommended that Decapod be used with books employing a "Manhattan" style layout. These layouts should be in rectangular columns, with content fitting and staying within those column boundaries.
Books that are not this style may produce PDFs with unexpected anomalies.
Future releases of OCRopus (which Decapod uses for page analysis and OCR operations) may support more complex layouts.
