Black Google technology: JPEG picture size one-third-Google, picture compression-IT information

The mobile Internet era, rapid consumption of mobile consumers a "psychological problem", many users simply turn off the data network of the picture display function. However, foreign media news, Google has developed a new algorithm to JPEG images to reduce the volume of one-third, this means that the future traffic consumption could fall sharply.

Although there are some new pictures on the Web file formats, but JPEG is one of the oldest and the most popular file format, this format was also used until the era of mobile Internet.

According to the technology news website Engadget reported that picture file as search giant Google has been compressed, Web content development work in compression. Google wants global network users (especially developing country users) download more quickly to a page, and picture, improve your Internet experience.

In the Compress pictures size, Google has introduced new file formats in the past, such as WebP, size without reducing the quality of the picture can be reduced under conditions of 10%.

The Google team has made new progress, they are using an open source compression algorithm Guetzli, optimized and improved, this algorithm to reduce JPEG picture size 35%.

The Google team said, this compression algorithm and Google has developed Zopfli algorithm (used to compress PNG images, or gzip compressed), conditions can not invent new file formats for existing file formats reduce data volume.

Earlier this year, Google also developed using artificial intelligence technology to compress pictures size technology , is said to be reduced in size to three-fourths, but its use rather than the extensive JPEG compression technology.

It was, for Smartphone users with Internet access using mobile cellular networks, the biggest consumption data primarily from the pictures and videos. Given the very high mobile operator data charges, many consumers do not actually use mobile phone to watch a lot of video. If the compression algorithm quickly grew in popularity, it will no doubt help reduce traffic overhead.

谷歌黑科技：JPEG图片体积缩小三分之一 - 谷歌,图片压缩 - IT资讯

移动互联网时代，手机流量的快速消耗成为消费者的一个“心病”，有一些用户干脆关闭了数据网络下的图片显示功能。不过据外媒最新消息，谷歌研发出了一种新算法，能够将JPEG图片的体积再减小三分之一，这意味着未来手机流量消耗可能会大幅下降。

虽然网络上出现了一些新的图片文件格式，但是JPEG依然是最古老、最为流行的文件格式，这一格式也沿用到了移动互联网时代。

据美国科技新闻网站Engadget报道，作为搜索巨头的谷歌一直在进行图片文件压缩、网页内容压缩方面的开发工作。谷歌希望全球的网络用户（尤其是发展中国家用户）能够更快速下载到网页和图片，改进上网体验。

在压缩图片体积方面，谷歌过去也曾经推出新的文件格式，比如WebP，能够将图片的体积在画质不降低的条件下减少一成。

谷歌的研究团队最近获得了新进展，他们利用了一种开源的压缩算法Guetzli，经过优化和改进，这种算法能够将JPEG的图片体积减少35%。

谷歌团队表示，这种压缩算法和谷歌过去研发的Zopfli算法（用于压缩PNG图片或是gzip压缩包）类似，可以在不发明新文件格式的条件下，对于现有文件格式减少数据体积。

今年初，谷歌还研发出了利用人工智能技术压缩图片体积的技术，据称可以将体积减少四分之三，不过其用途不如此次JPEG压缩技术广泛。

众所周知的是，对于利用移动蜂窝网络上网的智能手机用户，其最大的数据消耗主要来自图片和视频。鉴于目前移动运营商不菲的数据资费，许多消费者实际上并未利用手机观看大量视频。如果上述的压缩算法能够得到快速普及，这无疑将会帮助降低用户的流量开销。
