The newly risen research of artificial visual prosthesis is summarized. Based on the research on the imaging model of the visual prosthesis as well as the simulated experiment

a novel imaging model based on the selection of local prominent features is proposed

and a mean-option-score-based subjective assessment is designed to evaluate the performance of the model. The results of the experiment reveal that the imaging scheme can accentuate the areas with prominent features in the original image

so as to give observers a subjective perception of rich visual information. Thus

the model will provide a new approach for future research.
