Video Denoising, Deblocking and Enhancement Through Separable
1 Video Denoising, Deblocking and Enhancement Through Separable 4-D Nonlocal Spatiotemporal Transforms Matteo Maggioni, Giacomo Boracchi, Alessandro Foi, Karen Egiazarian Abstract—We propose a powerful video filtering algorithm that the nonlocal similarity between patches at different locations exploits temporal and spatial redundancy characterizing natural within the data [5], [6]. Algorithms based on this approach video sequences. The algorithm implements the paradigm of have been proposed for various signal-processing problems, nonlocal grouping and collaborative filtering, where a higher- dimensional transform-domain representation of the observations and mainly for image denoising [4], [6], [7], [8], [9], [10], [11], is leveraged to enforce sparsity and thus regularize the data: [12], [13], [14], [15]. Specifically, in [7] has been introduced 3-D spatiotemporal volumes are constructed by tracking blocks an adaptive pointwise image filtering strategy, called non- along trajectories defined by the motion vectors. Mutually similar local means, where the estimate of each pixel xi is obtained volumes are then grouped together by stacking them along an as a weighted average of, in principle, all the pixels x of additional fourth dimension, thus producing a 4-D structure, j termed group, where different types of data correlation exist the noisy image, using a family of weights proportional to along the different dimensions: local correlation along the two the similarity between two neighborhoods centered at xi and dimensions of the blocks, temporal correlation along the motion xj. So far, the most effective image-denoising algorithm is trajectories, and nonlocal spatial correlation (i.e. self-similarity) BM3D [10], [6], which relies on the so-called grouping and along the fourth dimension of the group. -

Technology developed by Green Parrot Pictures "can do exactly this," Doig said, and has been used by major studios on films such as "Lord of the Rings," "X-Men" and "Spider-Man." "Their technology helps make videos look better while at the same time using less bandwidth and improving playback speed," Doig said. Google-owned YouTube said Tuesday that it has bought (c) 2011 AFP an Irish digital video company whose technology can help improve the quality of amateur footage submitted to the video-sharing site. Google-owned YouTube said Tuesday that it has bought an Irish digital video company whose technology can help improve the quality of amateur footage submitted to the video-sharing site. Financial details of the acquisition of Green Parrot Pictures, which was founded by Anil Kokaram, an associate professor at the engineering school of Trinity College in Dublin, were not disclosed. YouTube said in a blog post that much of the 35 hours of video uploaded to the site every minute is "beautifully shot by professionals or aspiring filmmakers." "But some of YouTube's most popular or moving videos are shot using low-quality mobile phones and video cameras," said Jeremy Doig, director of Google Video Technology. "Take, for example, videos of recent protests in Libya," Doig said. "Although emotionally captivating, they can be jerky, blurry or unsteady. "What if there was a technology that could improve the quality of such videos -- sharpening the image, reducing visual noise and rendering a higher- 1 / 2 APA citation: YouTube buys Green Parrot Pictures (2011, March 15) retrieved 24 September 2021 from https://phys.org/news/2011-03-youtube-green-parrot-pictures.html This document is subject to copyright. -

Measuring Noise Correlation for Improved Video Denoising
MEASURING NOISE CORRELATION FOR IMPROVED VIDEO DENOISING Anil Kokaram∗, Damien Kelly, Hugh Denman, Andrew Crawford Chrome Media Group, Google Inc, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA ABSTRACT The vast majority of previous work in noise reduction for visual me- dia has assumed uncorrelated, white, noise sources. In practice this is almost always violated by real media. Film grain noise is never 1 white, and this paper highlights that the same applies to almost all 0.8 0.6 consumer video content. We therefore present an algorithm for mea- 0.4 suring the spatial and temporal spectral density of noise in archived 0.2 0 video content, be it consumer digital camera or film orginated. As an 20 15 10 15 example of how this information can be used for video denoising, the 10 5 5 spectral density is then used for spatio-temporal noise reduction in 0 0 the Fourier frequency domain.

In general, high res- ogy for video streaming over modern throughput-varying com- olution videos have better visual quality at high bit rates and low munication networks. A widely used ABR streaming method is resolution videos have better quality at low bit rate (see next to adapt the video bit rate to channel throughput by dynamically section for explanations). As shown in Figure 1, with multi- changing the video resolution. Since videos have different rate- resolution ABR streaming, users could always switch to the reso- quality performances at different resolutions, such ABR strategy lution with the best visual quality according to their available data can achieve better rate-quality trade-off than single resolution throughput[4]. ABR streaming. The key problem for resolution switched ABR is to work out the bit rate appropriate at each resolution. In this paper, we investigate optimal strategies to estimate this bit rate using Multi-resolution ABR both quantitative and subjective quality assessment. We use the Single-resolution ABR design of bitrates for 2K and 4K resolutions as an example of the Quality performance of this strategy. We introduce strategies for selecting an appropriate corpus for subjective assessment and find that at this high resolution there is good agreement between quantitative 4K and subjective analysis. -
