The wavelet transform has proved its eeciency in removing spatial redundancy. In the framework of hybrid coding schemes, this paper studies the way to combine the wavelet transform and a block matching motion estimation technique. Diierent coding schemes are presented which diier through the data on which the motion estimation and motion compensation are respectively applied. Simulations result...

-The distribution of malignant melanoma among the 4 major body sites (head, upper limb, lower limb and remainder (trunk)) was investigated for 37 white populations. Although UV radiation is generally considered to be the major aetiological agent, it was found that 75% of the tumours occurred on the relatively unexposed body sites. However, the sex differences in the incidence of melanoma at the...
