Hi, it seems to me the code can work for 64 x 64 dimensions. How to process pic of 512 x 512 dimensions?

Thanks

hi , good

Very useful, just a quick question:
Should a JPEG encoder add an EOB symbol to every block as this routine appears to or only those with a zero as the last element?

[Rimas Adnan]

I followed the steps you mentioned, but after running ijpegdemo an error occured at line 37 and I couldn't recover the compressed image (Error in ==> ijpegdemo at 37
        ac=acarr(ind1:Eob(n)-1);)

[Sarwan]

Similarly running ijpegdemo.m following error has occurred.

??? Undefined function or variable "accof".

Error in ==> ijpegdemo at 4
acarr=jacdec(accof);
