what epzs did that i couldn't be able to do with umh is, it fixed lot of
artifacts that require bigger search window. if i increase search param
with umh it increase the artifacts. same happen with esa.
i guess umh uses less predictors but a better search pattern. if we combine
both epzs and uhm, it should increase the quality further.
