摘要：This paper presents a comparison relating two different vision system architectures. The
first one involves a smart sensor including analog processors allowing on-chip image
processing. An external microprocessor is used to control the on-chip dataflow and
integrated operators. The second system implements a logarithmic CMOS/APS sensor
interfaced to the same microprocessor, in which all computations are carried out. We
have designed two vision systems as proof-of-concept. The comparison is related to
image processing time. Results reveal that one of the solutions to resolve the
computational complexity of computer vision algorithms is to perform some low-level
image processing on the sensor focal plane. This concept makes the vision systems more
compact as a system on chip and increases performance thanks to the reduction of dataflow
exchanges, with external circuits, and power consumption.
