Gents,  

I would like to learn a bit about the workings of the Discrete Cosine Transform technique, e.g. math background, PS implementation, etc; beyond 5116.DCT_Filter.pdf and TN5603.Filters.pdf which only discuss the usage of DCT filters. 

I am sure there is some good report on DCT basics somewhere at  Adobe's but their knowledgebase does not seem to cover PS at all. Could you give me a hint where I might find this info? 

Miklos
