CSA302 – Assignment 2001/02 FAQ

Question: Are we expected to find an inter-image coding extension to JPEG which really exists or can we describe our own compression technique which is possibly based on the concepts of video compression techniques?

Answer:  You may describe your own inter-image coding extension to JPEG.

Question: Does the inter-image coding necessarily have to be an extension of JPEG or can it be a completely different technology?

Answer: Well, the assignment says that it should be a JPEG variant. There are other ways of compressing data (which basically ignored the fact that it is image data), but I would rather the essay was about a technique which was largely JPEG based. Having said that, if you want to discuss the "different technology" with me first, that's ok too.

Question: Should there be any technical details in the essay on how the algorithm should be implemented or is just an overview enough?

Answer: There needs to be sufficient detail to demonstrate that your approach is feasible. This can either be a description or something more technical. The choice is yours.

Question: What level of originality do we have to go into. I mean, do you expect us to present you with an explanation of existing solutions or be original (with no very specific detail as you said in class)

Answer: You don't have to be original.

Question: In the essay title you said that "However, your solution must attempt to be scalable (e.g., it should not have to compare an image to every other image in the library). " How can we do an inter image encoding if we cannot do any comparison to other images?

Answer: My statement doesn't say you must not compare one image to any other. It says you shouldn't have to compare an image to *all* others.
