Size of compressed file

[gullibleretorted]

Hi there,

first of all thank you for sharing the code!
After I downloaded the Main Model L3C I tried out the compression of an example image with:

python l3c.py ./models/ 0306_0001 enc ./data/original/006239.png 006239.l3c

I was suprised to see that the compressed file is still quite large (882KB)

Size original image: 942 KB
Size compressed file(006239.l3c): 882 KB
Size of reconstructed file: 874 KB (The quality of the decoded .l3c file seems as expected lossless)

My question now would be: Is this compression rate normal?

Thanks a lot in advance!

Depends on the file! What's 006239?
