e o When errors are clearly visible, the blockiness of some artifacts distinguishes them from th riginal image content, suggesting a way of reducing these artifacts. Presumably, the human viewer k e identifies the artifacts by assuming the image does not have 8-pixel by 8-pixel block features. Bloc dge variance, the sum of squared differences between adjacent block edge pixels, is one simple s ...

Research for ezecuting large-scale motions of mobile manipulators is described. Mobile manipulator" are mobile bases with an attached arm which function in an integrated manner. Motivation i, given for moving the arm while the base i, moving. Thi, work applies reactive control concept, to achieve this type of motion. Tools for modeling Integrated arm-vehicle kinematics' and dynamics are di,cuss...
