Hough Transform Camera
iOS iPhone Photography
With HoughCam you can watch live footage from your camera transformed into hough space in realtime. Also you can save these transformed images with high resolution to your photo-library.
UPDATE: Some people report, that the app crashes immediately after launch. I testest it on both an iPhone 4 and iPhone 3GS and worked fine. I couldn't test it on an iPhone 3G, so it could be, that it doesn't work with it. If the app doesn't work for you, but you have an iPhone 4 or 3GS, or if the app does work, but you have an iPhone 3G, then please send me a mail, to help me clarifing this issue! Thank you!
