[Program doc] dm642.ZIP DL : 0: 在本文中，我們首先實作了一個針對壓縮視訊（像是 H.264/AVC）之畫面解析度改善的方法。接著，我們分析這個方法的模擬結果。-In this thesis, we first implement a spatial resolution enhancement algorithm for H.264/AVC compressed videos. Based on the analysis of the simulation results, we identify a few shortcomings of this algorithm, like some visual artifacts in the enhanced videos and some problems caused by scene change and fast motion. Then, we propose two methods to suppress these artifacts, including adding a median regularization term in the spatial-domain and using a median filter in the temporal domain. We also propose two methods, a global method and a local method, to overcome the scene change and fast motion problems. With these modifications, the artifacts and problems are suppressed significantly.

[Other] gabor_image_paper DL : 0: Example of a two-dimensional Gabor filterIn image processing, a Gabor filter, named after Dennis Gabor, is a linear filter used for edge detection. Frequency and orientation representations of Gabor filter are similar to those of human visual system, and it has been found to be particularly appropriate for texture representation and discrimination. In the spatial domain, a 2D Gabor filter is a Gaussian kernel function modulated by a sinusoidal plane wave. The Gabor filters are self-similar – all filters can be generated from one mother wavelet by dilation and rotation

[Report papers] Robust Spatial-spread Deep Neural Image Watermarking DL : 0: Watermarking is an operation of embedding infor- mation into an image in a way that allows to identify ownership of the image despite applying some distortions on it. In this paper, we present a novel end-to-end solution for embedding and recovering the watermark in the digital image using convolutional neural networks. We propose a spreading method of the message over the spatial domain of the image, hence reducing the local bits per pixel capacity and significantly increasing robustness. To obtain the model we use adversarial training, apply noiser layers between the encoder and the decoder, and implement a precise JPEG approximation. Moreover, we broaden the spectrum of typically considered attacks on the watermark and we achieve high overall robustness, most notably against JPEG compression, Gaussian blur, subsampling or resizing. We show that an appli- cation of some attacks could increase robustness against other non-seen during training distortions across one group of attacks — a proper grouping of the attacks according to their scope allows to achieve high general robustness
