Google reduce sizes of JPEG images by 35%




A team of researchers working for the company developed the Google new algorithm to compress image files combines excellent pressure intensity and visual quality high, resulting in a significant reduction in image files sizes in JPEG format, the company explained that the new Khoazmitha work to reduce image sizes by up to 35 percent compared with other algorithms used.

The need at the moment to such techniques, where the Internet has a number of pictures are endless, and wants everyone, including users and companies that work on the storage of those images, providing the possibility to download those images as soon as possible and look good accurate as possible .

The new algorithm called open source as the ” Guetzli “, and is working to reduce the size of large files without damaging the images in accordance with the standard JPEG, which offers the possibility to use the algorithm everywhere without having to change anything else.

And operating the new algorithm with web browsers existing tools and image processing, the company points out that it allows to reduce image file sizes without compromising significantly the quality of the image, and by targeting what is known as phase quantization compression process, a stage in which they can algorithms reduce the size of files while providing lower-quality images.

It can encode JPEG images process is divided into six distinct parts are converting color space and reduce the separation and division of the block and cosine transform discrete and quantization and coding random irregular, where the new algorithm focuses on the quantization phase, a phase that usually lead to the visual quality of the image is lost.

Joazrmah Guetzli works slower than the other options available, such as libjpeg, which is open source, and that users who want to download and use within their own business, and showed tests conducted by Google users prefer images produced through Guetzli compared with other coding algorithms for Besgah images JPEG.
