| dc.description.abstract | 近年隨著深度學習的崛起，在學術界、業界每隔幾個月就會有驚人的深度學習成果與作品誕生，同時也證明深度學習技術應用在影像方面有許多不凡的效果。本論文以使用卷積神經網路為主要方法，目的是使因自然光學失焦、拍照時手震等等因素產生的糢糊化影像恢復成清晰影像。本論文提出了三種網路架構：Auto_deblur、S-Net和AGDNet；在圖片輕微受損糢糊的情況下以選擇S-Net為佳，因為S-Net執行速度很快；在對糢糊程度較為嚴重的目標時主要以執行AGDNet效果最好，它整合了前兩種網路的構思與優點；除此之外本論文還提出了在訓練網路時改良損失函數使網路輸出更擬合真實清晰的圖像。本架構除了在解決糢糊化問題上有好的表現外，在超解析度成像(Super-Resolution)、解決圖片雜訊(Image Denoising)和影像恢復(Image Restoration)問題上同時也有好的效果。在實驗過程中，結果也顯示本方法較其他深度類神經網路和業界常用解法表現更加優秀。 | zh_TW |
| dc.description.abstract | In recent years, along with the rise of deep learning in academia and industry. There will be striking deep learning achievements and works every few months. It also proves that deep learning technology application has many great effects in the image. In this paper, the convolution neural network is used as the main method to restore out of focus images or blurred images to clear images. This paper proposes three network architectures: Auto_deblur, S-Net and AGDNet. In the case that the image is slightly damaged and blurred, it is better to select S-Net, because S-Net can execute quickly. AGDNet has the best effect when the image has a relatively serious target, which integrates the conception and advantages of the first two networks. In addition, this paper also proposes to the improved loss function in training the network so that the network output is able to fit more the real and clear images. In addition to its good performance in solving deblurring, this architecture also has good effects in image super-resolution, Image denoising and Image Restoration. The results also show that this method performs better than other deep neural networks and other commonly used solutions in the industry. | en_US |
