Google OAuth 2.0 allows user to share specific data with keeping their user names, passwords, and other information private.We will use Google OAuth Version 2.0 API. follow the link:
Harvard University researcher Walter Scheirer has developed a smartphone-based machine-vision system that automatically recognizes and counts specific animals. Scheirer says the system could help biologists make quicker, more accurate judgments about the health of fragile ecosystems. Although automated camera traps are already in use, they are not selective enough. "Right now, we have to manually go through every photo to identify species and separate photos of interest from false photos," says Princeton researcher Siva Sundaresan. The system starts by scanning the environment for objects that could be the animals it is looking for. It looks for pixel clumps that are new to the scene, then studies them to determine whether they represent any of the animals it has been trained to recognize. The algorithms analyze the content of each frame and look for patterns of pixels that identify the animal. Testing has shown the system can distinguish between three different species of ground squirrel 78 percent of the time. Scheirer says the goal is to develop an inexpensive, easy-to-use system that can automatically detect animals in any environment.
"Denied the right to travel without consent from their male guardians and banned from driving, women in Saudi Arabia are now monitored by an electronic system that tracks any cross-border movements. Since last week, Saudi women's male guardians began receiving text messages on their phones informing them when women under their custody leave the country, even if they are travelling together. 'The authorities are using technology to monitor women,' said columnist Badriya al-Bishr, who criticised the 'state of slavery under which women are held' in the ultra-conservative kingdom. Women are not allowed to leave the kingdom without permission from their male guardian, who must give his consent by signing what is known as the 'yellow sheet' at the airport or border."
