Question

I recently moved from a PC to a MacBook Pro. I’m starting to go through tutorials on Objective-C and developing in Cocoa. I do a lot of image processing algorithm development work (pixel by pixel manipulation) in my day job so I’d like to get create a test image processing app or two for OS X. I’m struggling to figure out where to start – let’s say I want to create a simple application (that I could reuse) like the following:

1. load an image from an open file option within a file menu
2. display this within the GUI.
3. Click a button to apply pixel by pixel processing
4. Update the displayed image
5. Save the processed image from the save option within the file menu

Any pointers or links would be most appreciated.

Thanks

Other info:

1. I’m pretty familiar with OpenCV within Linux – haven’t looked at using it within Objective-C/Cocoa/Xcode environment yet though – not even sure if this would be a good idea?

2. I guess it would be nice to use GPU acceleration as well, but I’m not familiar with OpenGL/OpenCL – so I might have to put that one on the long finger for the moment.

Answer 1

As you are looking at the Apple platform, you should look into the CoreImage framework – it will provide you most of pre-baked cookies ready to be consumed in your application.

For more advanced purposes, you can start off with openCV.

Best of luck!!
