Developers can build applications that can see and understand what’s in images in Google Photos with the release of Cloud Vision API. It’s going to help all kinds of developers who make applications, according to Google’s blog.

Using a REST API and advances in machine learning, Cloud Vision API can classify images, detect faces, and recognize printed words in different languages. Developers can also build metadata on their image catalog, moderate offensive content, and enable marketing scenarios through image sentiment analysis, the blog said. In future phases, Google will add support for integrating with Google Cloud Storage.

Some of the main features in Google Cloud Vision API include label/entity detection, where it can pick out the dominant entity in an image, as well as optical character recognition, where the API provides automatic language identification and supports a wide variety of languages.

EFF makes complaint about Google tracking student info
The Electronic Frontier Foundation (EFF) has launched a campaign called “Spying on Students” after it filed a complaint with the Federal Trade Commission (FTC) against Google for collecting and data mining students’ personal information.

The campaign will raise awareness about the privacy risks of school-supplied electronic devices and software, according to the EFF release. It examined Chromebooks sold to schools that use Google Apps for Education and found that Google’s sync feature for the Chrome browser is enabled by default, which means the company can track and store data for non-advertising purposes. The EFF wrote that many parents are unable to prevent Google’s data collection, since they have to use the Chromebooks at school. The EFF also said that Google assured the EFF that it will soon disable a setting on school Chromebooks that collects Chrome Sync data, but the EFF wants it to go further to protect the privacy of children.

Superfeedr welcomes Google Feed API users
Many websites are broken because of Google’s recent shutdown of its Feed API after six months of deprecation. Superfeedr is stepping in as an alternative, according to its blog.

Superfeedr wrote yesterday that it can achieve what Google’s API did. Superfeedr charges for its services, but there is a free tier available. A common request that Superfeedr is getting is for loading feeds using JavaScript and jQuery, explaining what to do in detail on its blog. Some of the other things developers can do with Superfeedr include retrieving multiple feeds in one single call, combining feeds, getting real-time updates in JavaScript, and adding a feed reader to any page.
