Javascript web browser detection

Feature detection also feature testing is a technique used in web development for handling differences between runtime environments typically web browsers or user agents , by programmatically testing for clues that the environment may or may not offer certain functionality. This information is then used to make the application adapt in some way to suit the environment: to make use of certain APIs , or tailor for a better user experience. Its proponents claim it is more reliable and future-proof than other techniques like user agent sniffing and browser-specific CSS hacks. A feature test can take many forms. It is essentially any snippet of code which gives some level of confidence that a required feature is indeed supported.

But browsers and standards are not perfect, and there are still some edge cases where detecting the browser is needed.

January 22, — A guest post by Hugo Zanini, Machine Learning Engineer Object detection is the task of detecting where in an image an object is located and classifying every object of interest in a given image. In computer vision, this technique is used in applications such as picture retrieval, security cameras, and autonomous vehicles. One of the most famous families of Deep Convolutional Neural Networks …. Object detection is the task of detecting where in an image an object is located and classifying every object of interest in a given image. In this post, we are going to develop an end-to-end solution using TensorFlow to train a custom object-detection model in Python , then put it into production, and run real-time inferences in the browser through TensorFlow. The first step to train a great model is to have good quality data. When developing this project, I did not find a suitable and small enough object detection dataset, so I decided to create my own. So I decided to build a Kangaroo detector.

And neither should they have to : arguably your web content doesn't need to look exactly the same across every browser and device and user might choose to view it on, as long as it still provides a good user experience and gives them access to the content and services required by their current browsing experience. To get your web content working well on all of the huge, diverse number of different web browsers and web-enabled devices that exist or even a good proportion of them , you're going to have to do some work, optimizing the layouts and content delivered to each browser, and sometimes even directing certain devices to completely separate web sites.
