It converts captured images into corresponding electrical stimulation patterns, according to which phosphenes are generated through the action of internal electrodes on the visual pathway to form visual perception. However, due to some restrictions such as the few implantable electrodes that the biological tissue can accommodate, the induced perception is far from ideal. Therefore, an important issue in visual prosthesis research is how to detect and present useful information in low\u2010resolution prosthetic vision to improve the visual function of the wearer. In recent years, with the development and broad application of computer vision methods, researchers have investigated the possibility of their utilization in visual prostheses by simulating prosthetic visual percepts. Through the optimization of visual perception by image processing, the efficiency of visual prosthesis devices can be further improved to better meet the needs of prosthesis wearers. In this article, recent works on prosthetic vision centering on implementing computer vision methods are reviewed. Differences, strengths, and weaknesses of the mentioned methods are discussed. The development directions of optimizing prosthetic vision and improving methods of visual perception are analyzed.<\/jats:p>","DOI":"10.1111\/aor.14022","type":"journal-article","created":{"date-parts":[[2021,7,28]],"date-time":"2021-07-28T04:40:21Z","timestamp":1627447221000},"page":"1141-1154","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["The application of computer vision to visual prosthesis"],"prefix":"10.1111","volume":"45","author":[{"given":"Jing","family":"Wang","sequence":"first","affiliation":[{"name":"School of Information Shanghai Ocean University Shanghai China"},{"name":"Key Laboratory of Fishery Information Ministry of Agriculture Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4802-1439","authenticated-orcid":false,"given":"Haiyi","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Information Shanghai Ocean University Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianyun","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Information Shanghai Ocean University Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1303-8898","authenticated-orcid":false,"given":"Heng","family":"Li","sequence":"additional","affiliation":[{"name":"School of Biomedical Engineering Shanghai Jiao Tong University Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanling","family":"Han","sequence":"additional","affiliation":[{"name":"School of Information Shanghai Ocean University Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruyan","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Information Shanghai Ocean University Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Information Shanghai Ocean University Shanghai China"},{"name":"Key Laboratory of Fishery Information Ministry of Agriculture Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,7,27]]},"reference":[{"key":"e_1_2_10_2_1","unstructured":"World Health Organization.WHO launches first World report on vision; c2020.
