Technology against vision architectures

Understanding what the problems are in robot-vision architecture, requires a better comparison of major features. But a zoology of vision machines is questioned when, aiming for a well informed architectural feature choice, a rapid presentation of technological trends in the field is proposed. Then an approach closer to physics prompts to a classification from a control point of view: it reveals some duality between operations and communications. A few visual operations are distinguished provided technology is not trailing behind. But emphasis should be put on communication networks, although they do not show any image processing specificity currently, and the conclusion addresses some limits in that respect
