基于深度學習的圖像超分辨率算法研究基于深度學習的圖像超分辨率算法研究

摘要：

隨著數(shù)字圖像的廣泛應用，對于圖像的質(zhì)量要求也越來越高。其中一個重要的方面是圖像的分辨率，即能夠展示圖像中更多的細節(jié)和更清晰的線條。圖像超分辨率技術(shù)能夠通過利用圖像中的低分辨率信息來重建高分辨率圖像。本論文從深度學習的角度出發(fā)，對于基于深度學習的圖像超分辨率算法進行了綜述和分析，并提出了一種新的基于深度學習的圖像超分辨率算法。

首先介紹了基于插值和濾波的傳統(tǒng)圖像超分辨率算法的不足之處，并引入了深度學習的概念。然后對于深度學習中常用的卷積神經(jīng)網(wǎng)絡(luò)進行了介紹，并解釋了其在圖像超分辨率中的應用。接著，綜述了目前基于深度學習的圖像超分辨率算法的發(fā)展歷程和研究現(xiàn)狀。分析了不同算法的優(yōu)缺點，并根據(jù)研究結(jié)果提出了一種新的基于深度學習的圖像超分辨率算法。

本論文設(shè)計的算法使用了深度學習中的殘差學習框架來訓練模型，同時采用了圖像去噪和圖像超分辨率聯(lián)合訓練的方式來提高模型的準確性和穩(wěn)定性。該算法在實驗中得到了較好的結(jié)果，能夠達到較好的超分辨率效果。
