I need some help regarding the 8*8 blocks that we need to create for the implementation of jpeg. How am i supposed to make them?
I am not very fluent (good at) matlab programing. So some comments explaining how the code is being executed would be highly appreciated.
 

To start with u need to use a image with integral multiple of 8 such as VGA resoltion ( 640x480) which contains total 80x60 -8x8 blocks then use two for loops with modulus ....then you can generate the micro -blocks of 8x8 size
 
Your suggestion was very useful, I do understand that for starting as a beginner I would require an image with multiple of 8s resolution. You have mentioned to for loops, I am unable to use the loops and understand the code for these loops. Could you please guide me regarding the code for implementation as well as understanding.
