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 References: A1: [login to view URL] A2: [login to view URL] A3: [login to view URL]

Hi I will provide simple tools using Imagemagick and OpenCV. I will do all that features for 550$ and 2 days. I will need further information to start working Thanks Relevant Skills and Experience I used an app with these feature in minimum 2 apps in this year. They were OCR apps intended for parsing and saving tax form data into database. I used preprocessing engine to standardize input in OCR Proposed Milestones $555 USD - Image preprocessing app In order to make these requirements clear please answer those questions. 1) Can you send me sample images to give you quick PoC for some APPs? 2) What are the performance requirements? How efficient should the product be? 3) Should it have batch processing mode too?
