However, due to the increased dimensionality of time-resolved renders, storage and data bandwidth are significant limiting constraints, where a single time-resolved render of a scene can take several hundreds of megabytes. In this work we propose a learning-based approach that makes use of deep encoder-decoder architectures to learn lower-dimensional feature vectors of time-resolved pixels. We demonstrate how our method is capable of compressing transient renders up to a factor of 32, and recover the full transient profile making use of a decoder. Additionally, we show how our learned features significantly mitigate variance on the recovered signal, addressing one of the pathological problems in transient rendering.","PeriodicalId":216038,"journal":{"name":"ACM SIGGRAPH 2019 Posters","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115597443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have proposed the automatic display zoom system for presbyopic people [Fang and Funahashi 2018]. However, some of the information on the small display has gone out of it after zooming-in (Fig. 2(a) to (b)). It is necessary to scroll it frequently, and a bother. On the other hand, a conventional partial zoom means like a magnifying glass is also usually provided (Fig. 2(a) to (c)). The part around a zoomed area is cut off, and it is necessary to move the glass frequently too. People sometimes want to skim through sentences and understand an overview. By the way, although it is difficult to read blurry words (Fig. 3(a)), you can guess and read a sentence includes the blurry words when some other words are clear (Fig. 3(b)). Therefore, we reconsider the zoom-in method for presbyopic people. For example, the area paid attention is zoomed in to read clearly, and the magnification rate of the area around it is gradually reduced to zoom-out rate so that all information is displayed in the small display even though some words are zoomed out. It is expected that you can guess and read also the unzoomed-in words like blurred words around the clear zoomed-in words. We propose a suitable partial zoom-in function that allows you to skim a document.","PeriodicalId":216038,"journal":{"name":"ACM SIGGRAPH 2019 Posters","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123006682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A graph structure of each frame in an input line drawing sequence helps to find correspondences of regions to be colorized between frames. However, it is difficult to find precise correspondences of whole frames only from a single reference image, because the graph structure tends to change drastically during the sequence. Therefore, our method first finds an optimal image from multiple reference images according to a cost function that represents shape similarity between nodes and compatibility of node pairs. While it is necessary to prepare several manually colored reference images, our method is still effective in reducing the effort required for colorization in anime production. We demonstrate the effectiveness of our method using actual images from our production.","PeriodicalId":216038,"journal":{"name":"ACM SIGGRAPH 2019 Posters","volume":"48 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114123964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of particular importance has been the realistic modeling and rendering of layered subsurface scattering in skin for which various bio-physical models have been proposed based on the spectral distribution of chromophores in the epidermal and dermal layers of skin [Donner and Jensen 2006; Donner et al. 2008; Jimenez et al. 2010]. However, measurement of the spectral parameters of absorption and scattering of light for such bio-phyisical models has been a challenge in computer graphics. Previous works have either borrowed parameters for skin-type from tissue-optics literature [Donner and Jensen 2006], or employed extensive multispectral imaging for inverse rendering detailed spatially varying parameters for a patch of skin [Donner et al. 2008]. Closest to our approach, Jimenez et al.

As the art of representing images with dots, one of the key problems is the placement of dots. In general, they should be distributed evenly, and with some randomness at the same time. Blue noise methods provide these characteristics and are used by state-of-the-art gray-scale algorithms to distribute dots. Color stippling, however, is more challenging as each channel should have even distribution at the same time. Existing approaches cast color stippling as a multi-class blue noise sampling problem and provide high quality results at the cost of a very long processing time. In this paper, we propose a real-time structure aware method for color stippling, based on samples generated from an incremental voronoi set. Our method can handle an arbitrary input color vector for stippling and produce significantly better results than previous methods, at real-time frame rate. We evaluate the perceptual quality of our stippling with a user study and its numerical performance by measuring the MSE between the reconstructed image from the stippling and the input image. As a result, the real time performance of our method makes interactive stippling editing possible, providing the artist with an effective tool to explore quickly a wide space of color image stippling.","PeriodicalId":216038,"journal":{"name":"ACM SIGGRAPH 2019 Posters","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134057414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
