What Is Proprietary Software? 5 Ways It Beats Open-Source Software

Have you given any thought to the way the software on your computer is designed? If you bought your PC in person, chances are it’s running proprietary software: software that’s typically created for profit, for which you can’t edit the source code yourself. When you agree to a lengthy End User License Agreement when installing a new program, you’re likely installing proprietary software. Why is most of the software we encounter on Windows, macOS, and our smartphones proprietary? Well, there are certain advantages to this style of software creation and distribution that lead many developers to see it as the...

Semantic Image Segmentation with DeepLab in Tensorflow

Posted by Liang-Chieh Chen and Yukun Zhu, Software Engineers, Google Research

Semantic image segmentation, the task of assigning a semantic label, such as “road”, “sky”, “person”, “dog”, to every pixel in an image enables numerous new applications, such as the synthetic shallow depth-of-field effect shipped in the portrait mode of the Pixel 2 and Pixel 2 XL smartphones and mobile real-time video segmentation. Assigning these semantic labels requires pinpointing the outline of objects, and thus imposes much stricter localization accuracy requirements than other visual entity recognition tasks such as image-level classification or bounding box-level detection.

Today, we are excited to announce the open source release of our latest and best performing semantic image segmentation model, DeepLab-v3+ [1], implemented in Tensorflow. This release includes DeepLab-v3+ models built on top of a powerful convolutional neural network (CNN) backbone architecture [2, 3] for the most accurate results, intended for server-side deployment. As part of this release, we are additionally sharing our Tensorflow model training and evaluation code, as well as models already pre-trained on the Pascal VOC 2012 and Cityscapes benchmark semantic segmentation tasks.

Since the first incarnation of our DeepLab model [4] three years ago, improved CNN feature extractors, better object scale modeling, careful assimilation of contextual information, improved training procedures, and increasingly powerful hardware and software have led to improvements with DeepLab-v2 [5] and DeepLab-v3 [6]. With DeepLab-v3+, we extend DeepLab-v3 by adding a simple yet effective decoder module to refine the segmentation results especially along object boundaries. We further apply the depthwise separable convolution to both atrous spatial pyramid pooling [5, 6] and decoder modules, resulting in a faster and stronger encoder-decoder network for semantic segmentation.

Modern semantic image segmentation systems built on top of convolutional neural networks (CNNs) have reached accuracy levels that were hard to imagine even five years ago, thanks to advances in methods, hardware, and datasets. We hope that publicly sharing our system with the community will make it easier for other groups in academia and industry to reproduce and further improve upon state-of-art systems, train models on new datasets, and envision new applications for this technology.

Apple Maps shows you the nearest bike-sharing stations

 Apple has signed a partnership with Ito World to add bike-sharing data in Apple Maps in over 175 cities across 36 countries. The feature is now live and helps you find the nearest station by typing “bike sharing” in the search bar or the name of the service. Once again, Apple chose to integrate an existing data set instead of putting together this data in-house. Ito World has… Read More

Raspberry Pi Media Center: How to Install Kodi on Raspbian

You want to turn your Raspberry Pi into a media center, but you also need it for other tasks? Perhaps you’re using your Pi for programming, or playing Minecraft. It might have a role as a general project machine, meaning you need regular access to Raspbian. One solution to this might be to keep several microSD cards at hand, each with different operating systems installed. You might have one with Raspbian ready to run, another with a retro gaming distro, and a third with OSMC, openELEC, or LibreELEC. These are the three Kodi-based Raspberry Pi distributions, and the most common...

The Best Torrent Clients to Replace uTorrent

If you’re one of over 100 million uTorrent users, you should immediately upgrade to the latest version of the BitTorrent client. In November 2017, Google’s Project Zero identified a vulnerability, which BitTorrent Inc. (the company that owns and develops uTorrent) patched just in the nick of time. While the patch was only deployed to the Beta version at first, it has progressed to the Stable version in the meantime. It’s not the first time that uTorrent came under pressure. Criticized for bundling bloatware and containing annoying banner ads, one of their biggest faux-pas yet was revealed in 2015: uTorrent bundled...

Copyleft vs. Copyright: 3 Key Concepts You Need to Know

Copyright infringement is one of the biggest problems of the internet age. Never before has it been easier to infringe on intellectual property rights, and never before has it been harder to prevent others from stealing one’s hard work. As a creator, you need to protect your intellectual property: photographers should copyright photos and images, software developers should use proper software licenses, bloggers should issue DMCA takedown notices, etc. But that can be quite a headache, especially if you’re prolific and your work is popular. Which is why many creators are adopting copyleft instead. Here’s everything you need to know...

How to Change Your Facebook Password

When was the last time you changed your Facebook password? Although there are pros and cons of changing your password too frequently, using the same password as when you created your account eight years ago is definitely not best practice. Let’s try another one. In addition to Facebook, how many other sites, accounts, and web portals share the same password? Again, if you answered anything more than “zero,” you’re not following the advice of security experts. Whether you’ve been hacked, you’re worried about getting hacked, or you just want to boost your online security, now could be a good time...
