Hi I am new to IOS developing. I've been searching for a while, just can not find a good example.
I like to create an app dynamically detect paper, The app should be able to generate dynamic camera overlay by analysing current camera scenes.
I can program the sampling and detection algorithm myself, but really not good on the IOS interface and technique.
I am using objective-C as programming language.
I like to know:
1, how to change the camera overlay in real time?
2, how should i put a ticker that repeatedly check camera scenes?
3, how can I access and modify a picture from iOS objective C?
Please give me some ideas or show me some examples.
