| Abstract: | 因為被拍攝的螢幕的顯示器的像素排列，與手機像素的排列出現干涉現象，兩個排列在疊加的過程中就會形成出現了彩色和形狀不規律的條紋，就是摩爾紋。與其他影像還原的任務不同的是，去除摩爾紋的困難點在於，摩爾紋出現的頻率域很廣，不只存在於高頻，也同時出現在低頻中。此外，摩爾紋的形狀是不規則的，摩爾紋的色彩也會產生扭曲，所以是一個有挑戰性的任務。本論文提出一個基於多尺度融合機制去除摩爾紋的網路模型和利用摩爾紋的轉移做資料擴增的方法，可以增強去摩爾文的表現，根據實驗的結果顯示，我們的模型比去摩爾紋領域方法表現的更好。
Taking images on a digital display may cause a visually annoying optical effect, called moiré, which degrades image visual quality. Because the pixel arrangement of the display of the screen being photographed interferes with the pixel arrangement of the phone, the two arrangements are superimposed in the process of forming the color and shape irregularities of the stripes, which are moire patterns. Unlike other image restoration tasks, the difficulty in removing moire patterns is that moire patterns appear in a wide range of frequencies with irregular shapes and rainbow-like colors. Thus, removing moiré patterns is a challenging task. In this thesis, we propose an Image Demoiréing Multi-scale Fusion network (DMSFN) to remove Moiré patterns and a method for data augmentation using the transfer of Moiré patterns, which can enhance the performance of demoiréing. According to the experimental results, our model performs favorably against state-of-the-art demoiréing methods on benchmark datasets. |
