started work on this here: https://github.com/maxcan/GPUImage2/tree/mc01.1-add-hough-line-detection
very preliminary, but any thoughts / feedback / suggestions welcome.

Im working on an archery scoring program, and I'd LOVE to see if I can test this. I'm a complete image processing and iOS/Mac newb, so any help you can give to me to get this up and running on a test image would be great.

This would be awesome to see. We're working on a screen-based OCR system, this would be a key piece in detecting lines of text! (Combined with being able to attach GPUImage to a screen recording AVCaptureSession).

I'm working on driver license detection and recognition for OCR system. I'm capturing card image using AVcapturesession and trying rectangle detection by using Hough transform. So I need preprocess captured image by using GPUImage2 library in Swift 5.0, but I can't build it in Swift 5.0. there are so many errors.

Ase, not much help on using Hough for this, but there's probably other
solutions as there are a lot of CC capture apps right?
EG -- they're just scanning the barcode!

@ase, I found this that might help you?
https://github.com/garnele007/SwiftOCR no experience, but I'd have started
with a higher level library. I'm lurking here as I'm hoping one day to
detect arrow shafts in a target, which is pretty niche, but it feels like
card scanning is a "solved" problem at this point, so unless you're doing
it for a learning project, I'd just find something that's targeted at your
problem.
