ios - Corner detection of an image in Camera -


i new ios programming , trying ios new programming language - swift, see libraries available , forth. currently, trying create new project in xcode 6 takes picture of document. want corner detection. user can make corners larger , smaller (depending on user) he/she can crop image. example, office lens app.

i did few researches couple developers suggested use gpuimage. compatible ios8? other tools or easier configurations available can me needs get?

are there other libraries out there can work xcode6.1 or later ios8? not know 3rd party libraries or examples out there can pin-point me right direction regarding how can corner detection?

any tips/suggestions great, can learn , better piece. thanks!

image feature detection pretty difficult stuff. might want take @ library called opencv. it's c based api that's built on top of opengl. it's pretty advanced framework that's doing advanced image processing, unless you're senior software developer may on head.

gpu image may work you. yes absolutely works under ios. it's written in objective-c should callable swift

the news corner detection should pretty straightforward problem. doesn't mean easy, straightforward.
