Image preprocessing

Dead freelancer,

I'm looking for an image processing professional to build a small C# console app (or winform app, ref A3) that preprocess an image of a text document taken by a digital camera (of a smart phone) before performing OCR

The preprocessing should:

1. Detect document's edegs and deskew to correct perspective (using affine tranform correction) (ref A1, A2)

2. Trim to remove borders

3. Dynamic binarization (only on the main image after deskew and trimming)

4. Noise removal, despeckle

5. Brightness correction including glare removal (that are caused due to document angle with respect to light sources)

6. Shadow removal

7. Hole punch removal

8. Line removal (to keep only text)

9. Reconstruct text

10. Text sharpening

Preferred technology in OpenCV.

The input is a URL to a JPG image file and the output image should be written to the local computer in PNG format.

Output should be small C# application (or winform) with source code and all dependencies running on my local win 7 computer

Please state your preferred technology, past experience and if possible provide links to those projects.

Link to sample images with be given to submitters
