Research goals

    This laboratory has the following two goals.
   The first goal is to develop efficient systems for visual perception and cognition inspired by the visual nervous systems. The visual nervous systems perceive and recognize visual signals efficiently in terms of both energy and time, while understanding of visual information is one of the most difficult task for conventional computers even though its processing speed is much faster than that of neurons. Learning from the advantages of nervous systems is a promissing way to develop noble visual systems.
    The second goal is to reveal how the efficient visual signal processing is accomplished in the visual nervous systems, including the retina and the visual cortex. We have to reveal it before learning from the visual nervous systems because they remain poorly understood.
    Understanding the visual nervous systems and developing noble systems for visual perception and cognition inspired by the nervous systems: these two points are the keys of this laboratory.
