Why we call it Cognitive vision?
Because in the human vision the knowledge plays a important role, we
anticipate, we use previously acquired information, we use information
from the knowledge we have of the environment, we recognize, we
interprete. Human vision is a
intelligent vision not limited by the data obtained from the physical
reaction after a visual stimulus, it also incorporates a serie of
mechanisms that try
to assure that all the knowledge, as much as the internal (of the own
observer)
as the knowledge of the environment, is used .

Why we call it Emotive vision?
Because the affective states play a very important role in many aspects
of the human activity and above all in the interaction with others. The
fact of including emotional assessment in an artificial vision system
adds additional information that can explain behaviors that could not
be understood without the affective factor. Therefore if we want to
equip the robot with the communication skills of humans the vision
system will need to consider the incorporation of a mechanism of visual
assessment of emotions.
