help for lossless compression of image

Hi,

As you know, Huffman encoding is one of the most popular lossless compression encoding. For instance, in lossy-JPEG you you use DCT, Quantization for code redundancy and then Huffman encoding to compress the image which is the lossless part. In order to compress the image as 'lossless' can I use Huffman directly by neglecting DCT and Quantization part?

I searched for lossless compression in web but I see that there are some methods like predictive coding, difference coding etc. for lossless compression. If anyone help, I will be very glad

Thank you.
