image compression - "amelie.quinet" - Apr 5 7:44:33 2006

Hi,

I m working on image compression for my final training course. I am 
asked to compress the images 1600*1200 the most I can with the less 
loss I can...

 I am working with matlab, and trying to understand jpeg and jpeg2000.

In fact my boss wants me to use jpeg2000 but EBCOT is very difficult. 
So i wanted to know, what makes jpeg2000 so different from jepg except 
DWT ? And what can I add in jpeg algo to improve the results, thats to 
say, the ratio and the loss ? (I don't want to use jpeg with no loss).
I know it s not a very technical question but I hope sbdy will have 
answers for me.

Thanx

Hi prathima,
  which image compression standard you follow ?... i am also doing JPEG image
compression standard.but i am going to implement in VLSI.i have a whole C++ code
for JPEG encoder.how can i send to you?  

with regards
