Foveal vision reduces the data volume by utilizing a spatially variant resolution. A high resolution is maintained in the fovea where it can be used by computer vision algorithms, while the resolution is reduced in the periphery where it is less important. This paper focuses on the hardware architecture of a system that maps a conventional high resolution uniformly sampled sensor to a variable resolution output. The key feature of the proposed architecture is that it employs a separable forward mapping which requires a small amount of FPGA resources.
