- Besides eye-acceptability, do we have other measurements to
- test the quality of decompressed video pictures from different
- compression algorithms and programs?
-
- Recently, I have read and saw something about video compressions.
- But, it seems that there is no certain way to tell people how
- good or how bad these reproduced images are, i.e., there is no defined
- technical standards to classify those images. Maybe, there are some
- common test methods, but I just haven't learned them. Do you know
- some of these methods to test compressed-decompressed video images?
-
- Many vendors just show us the video pictures and tried to tell us they
- were PERFECT. It is possible other people can not see the difference
- between the original and reproduced ones, but I alway can. I ask for
- measurement data, or technical data and curves about the image quality,
- they don't have. Eye-acceptability? it doesn't sound so technical to
- me. :-) :-) :-)
