Flattening a image of book with Photoshop

I am trying to figure out how I can "flatten" an image of a page in a book. The book is very tricky, as it is 4 or 5 inches thick and cannot be photocopied or scanned. I have taken some pics of it with my digital camera, to attempt an OCR, but the curvature of the book is really screwing the OCR process up.

Would there be anyway to fix this using photoshop? I have posted a low-res (200k) and high-res (~3MB) files at the following links,

There is a way to straighten out the text, whether it would be good enough to work with OCR I don't know. You could try this:-

Pull several horizontal and vertical guides onto the image. Hit CTRL + T to enter Free Transform. In Free Transform, click on the Image Warp button on the Tool Options bar. This will put a grid over the image with control handles at each corner. By dragging on the grid intersections and the control handles, you can warp the underlying image in whatever way you want. You will need to be patient, using small careful movements to line up the lines of text to the guide lines.

I would also suggest increasing the contrast a bit using Levels.

Good Luck!
