siggraph2016_colorization试玩
前两天看到日本早稻田大学利用深度学习从原画中提取线稿的黑科技，发布了论文，但是并没有可以一试的源码。但是他的另一项黑科技给黑白照片上色，可以在git上下到试用的源码，不过，没有训练的源码。git地址：在开始试用之前，我们先要配置一下环境
以上都是需要安装的，本人是在OS X下安装的，大致步骤如下：首先我们需要安装torch
# in a terminal, run the commands WITHOUT sudo
git clone /torch/distro.git ~/torch --recursive
cd~/ bash install-
./install.sh
先是从git上下载安装文件，下载完成后先安装LuaJIT，LuaRocks需要的环境，再安装LuaJIT，LuaRocks。安装完成后还会提示你将torch添加的你的path中，运行命令如下即可
# On Linux with bash
source~/.bashrc
# On Linux with zsh
source~/.zshrc
# On OSX or in Linux with none of the above.
source~/.profile
然后我们就可以用LuaRocks来安装torch,nn,image以及nngraph了
luarocks install nn
luarocks install image
luarocks install nngraph
环境配置完成之后我们先要下载官方训练完成的模型，可以通过下面的语句来下载sh download_model.sh也可以直接在下载下载完成后就可以使用了，使用方法th colorize.lua &input_image&[&output_image&]比如th colorize.lua ansel_colorado_1941.png out.png注意一下，图片大小最好不要超过512x512px，不然会就较慢。下面是我试玩的一些例子
从上面的例子可以看出，在风景图片的处理上表现还不错，但在人像上还稍显不足。

Registration is now open for , the world’s leading annual interdisciplinary educational experience showcasing the latest in computer graphics and interactive techniques. With the tagline “Render the Possibilities,” SIGGRAPH 2016 will be held at the Anaheim Convention Center, 24-28 July 2016.SIGGRAPH has announced a number of first-time exhibitors for the 2016 event. U.S.-based companies that will be exhibiting at the conference for the first time this year include Intervoke Technologies, Pixel Plow, Puget Systems, and Yost Labs, Inc. They join eight other tech companies from around the world as first-time exhibitors: Binary Alchemy/G ftrack/S HoloDigilog Human Media Research Center/K Live2D Inc./J Presence Pictures/S Simlens/C Skolkovo Foundation/R and, Umbra/Finland.In related SIGGRAPH news, organizers of the 2016 conference have announced the launch of a character design contest. Entitled the “Spirit of SIGGRAPH,” the contest seeks to challenge artists and designers to create an original character design that embodies the excitement and energy of the annual conference. The new character design should also reflect the creative and inventive spirit present in the fields of computer graphics and interactive techniques. SIGGRAPH consciously chose to crowd-source the winning design given the design would be most meaningful if it was created by a member of the international SIGGRAPH community. The creator of the winning design will be awarded a complimentary, full-conference registration to SIGGRAPH 2016, as well as social media exposure.
through 15 April 2016.SIGGRAPH 2016 Conference Chair Mona Kasra, said, “We are designing this year’s event for those who are truly passionate about the interconnection and collaboration between graphics, interactivity, enhanced and virtual realities, games, mobile, robotics, digital art and visualization. For more than 40 years, SIGGRAPH’s goal has been to inspire, educate, and exemplify innovative approaches to the various global communities that co-exist within the arenas of computer graphics and interactive technologies. In 2016, our slogan is to ‘Render the Possibilities’ – so this year, we will celebrate the transformational capabilities that arise when systems, unprecedented ideas and revolutionary techniques intermingle. These possibilities are limitless, and can give birth to inspiring creativity, breathtaking new art forms and never-before-seen uses of technology.” &For a taste of this greatness,
for a preview of the famed history of the SIGGRAPH Computer Animation Festival (CAF). Since 1999, several festival selections have gone on to be nominated for — and awarded — the Oscar(R) for “Best Animated Short.” Most recently, the 2016 Academy Award winner “Bear Story” was presented during the 2015 CAF.Stats from the 2015 conference include:Over 15,000 attendees from the United States and over 70 other countries, including Canada, Japan, and the United KingdomNearly 900 pieces of progressive contentMore than 1,500 speakers, contributors, and exhibitorsTo register for SIGGRAPH 2016, visit .&
