A part of my final year project need a JPEG code in matlab to compress an image before transmission.

If any one have it please help me. :cry::cry::cry::cry::cry:
 


hi
if such a function exist just open the toolbox folder and open its m file
trace it step by step so that u could understand its function
 

Go to MatlabCentral

h**p://www.mathworks.com/matlabcentral/fileexchange/loadCategory.do

and search for jpeg. You can find several files in "Image Processing -> Compression".
