Abstract
En 中文
Color spiking encoding and opponent preprocessing are critical for energy-efficient object perception in the human visual system. Emulating the retina and brain's integration of spatial and chromatic spiking signals holds promise for enhancing the efficiency of vision sensors. Here, we introduce an artificial visual neuron array that generates excitatory or inhibitory spiking responses to specific wavelengths with orientation selectivity. The neuron array can function as double-opponent receptive fields for spatial-chromatic opponent preprocessing to color signals, emulating the neural pathway from the retina to the cortex. With the color spiking preprocessing function of the neuron array, the recognition accuracy is improved almost twofold compared to direct perception of underexposure objects, and the noise robustness is also strengthened. This architecture leverages biological mechanisms for simultaneous spike encoding and antagonistic preprocessing of color information, offering the potential for highly efficient neuromorphic vision systems.
