This isn't 3D related, so I'll put it in here.

For my senior project I'm trying to adapt JPEG-LS for use in a digital camera. The biggest downfall to using JPEG-LS in a digital camera is the buffer requirements for the process. Since there is a predictor step, I'd need to be able to buffer up to two lines. My biggest headache is how to not need to buffer two entire lines since I only need 4 pixels for each individual pixel. For example)

c b d
a x

x is the current pixel being predicted and the other letters are the other pixels I need in relation to the current pixel. This allows me to detect horizontal and verticle lines and find smoothness.

Anyone have any ideas?
