I am looking for a javascript image manipulation script, that would take an image of a paper document as input and will allow to output a straightened/cropped version in canvas (similar to Microsoft Photo Lens document detection). Functionality desired: - corner detection and mark - edge curvature/perspective detection and mark - detected area highlight - edit detection/crop area through points (for corners) and curve/spline editing for edges - straighten any curved/perspective areas - crop to selected area - rotation by specified number of degrees (positive or negative numbers) - implementation of the "find text regions" functions from MarvinJ to highlight text regions, found regions should be editable Script should make use of established libraries, like MarvinJ. I am opened to discuss alternatives as long as it is a well established free framework, but the preference is MarvinJ. Work will be classified as work made for hire.

I\'m interested in this project. I have done quite a bit of image processing but never with Javascript, but I\'m interested in doing this. I did checkout MarvinJ today (based on your suggestion) and played around with it a bit. I think all of what you\'re asking for is doable. The only thing to add to your description is that if you want the text to be editable, we\'ll have to use some OCR library, so tesseractjs is a good candidate. But you will also have to be reasonable in what languages are supported. I have used tesseract in the past (although not js), and it does really well in English especially if the text region detection is done before hand and i\'ve verified that MarvinJ does a good job of that.\r\n\r\nThe user interface will be somewhat like the demo on MarvinJ\'s website ([login to view URL]) except it won\'t have the sending to the server portion. \r\n\r\nI\'m splitting it into 3 stages (milestones), the automatic detection, the editing, and the text detection/recognition.\r\n\r\nPlease let me know if you\'re interested. Also, i\'d be willing to do a proof of concept of the detection milestone before we get started, but i think the bidding on the project closes soon.
