How to do lossless compression with wavelets along with ROI

Hi all,
I'm currently starting a project with above titled problem. This is not about direcly a code. Question I'm having are...
- Does separating an image in to LL,LH,HL,HH parts actually do a lossless compression? (because neglecting LH,HL,HH will compress it lossyly).
- If I want to compress only some parts lossless (ROI), can It be done only rounding Non ROI parts of the LH,HL,HH ? Is this the standerd way?
- Are there any sugestions better than this?
Can anybody give me some hints about these questions.
