In order to solve this problem, a multi-resolution feature extraction algorithm is proposed. Given the extracted features, the proposed auto-focusing system can provide the ideal focusing position using phase correlation matching. Since the proposed system accurately estimates the phase difference in the out-of-focus blurred image under low illumination, it can provide fast, robust auto focusing.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783848438983\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783848438983","offer_id":39457422704733,"sku":"9783848438983","price":23.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/9ce0ebe0-c524-46dd-a0ef-70540350803d.jpg?v=1776145903","url":"https:\/\/shop.autorenwelt.de\/en\/products\/sensor-based-auto-focusing-system-von-jinbeum-jang-yoonjong-yoo-joonki-paik","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
