Here we are, with a majority of our lives dependent on not only mobile apps but a variety of other such technological tools that help ease various facets of our lives. But if there’s one thing you should know about technology, it’s that it never stops evolving; so much so, that today, mobile apps are very ordinary now. But since apps, mobile or web, along with multiple other solutions remain crucial drivers of business across the entire gamut of industries in the world, and there has been plenty of innovation to help enterprises to differentiate their offerings from their rivals in the market. One such novelty that has recently emerged is face and emotion recognition technology. Don’t get us wrong, this technology has been around for a while now, but their implementation in the context of improving customer experience is relatively recent.

Nonetheless, they are here and how! Microsoft offers a terrific solution for the integration of such technologies via its Cognitive Services APIs that are aimed at facilitating the development of really advanced apps where the driving principle is the organic user interaction, no matter the platform or device. The APIs make use of machine learning, a subset of artificial intelligence, and are widely deemed highly conducive for the development of high-level apps.

So, if you, too, are planning to get started with using Face and Emotions recognition technology for your Xamarin.Forms app, we have listed some of the necessary steps to help you get started with it.

1. Cognitive Services APIs subscription: First things first, get a subscription of the service you require, i.e., Face and Emotion APIs. It may also help to remember that Cognitive Services offer RESTful APIs, i.e., one can interact with them via HTTP requests irrelevant of the platform provided you use a language that includes REST support.

Here’s a snippet that shows how an image is sent to the emotion recognition service:

POST https://api.projectoxford.ai/emotion/v1.0/recognize HTTP/1.1
Content-Type: application/json
Host: api.projectoxford.ai
Content-Length: 107
Ocp-Apim-Subscription-Key: YOUR-KEY-GOES-HERE
{ “url”: “http://www.samplewebsite.com/sampleimage.jpg” }

P.S.: Add your key and replace the image URL with the address of the target image.

2. Create the app: For this step, first launch Visual Studio, of course, and then when the New Project dialogue box pops up, go to Visual C#, the cross-platform node, and then select Blank XAML app template. The next step is to call the FaceEmotionRecognition solution.

Those are the most fundamental steps of the process. But if you are still wondering what comes next, well, you will need to introduce plug-ins, install NuGet packages once the solution is right to go, design the UI, and so forth.

Though it may seem like a long drawn out process, trust us when we say the union of these services with Xamarin mobile apps will enable companies to deliver unprecedented levels of natural interaction, thus significantly elevating users’ experiences and, consequently, the business.

When developers set out to decide upon a PHP framework for their development project, they look for a solution that is not only highly organized but also fares exceptionally well when it comes to code that is maintainable and reusable in equal measure. And rightly so, because such qualities are crucial for any web app development project where the goal is to build a robust product without spending more time and effort than is necessary. And given how much they are in demand all over the globe, it should come as no surprise that the market is brimming with a plethora of PHP frameworks to choose from.

And, despite the abundance of options, the choice almost always comes down to just two names: Laravel and Symfony, owing to their top-rated abilities in the context of their usability, highly productive features, and so much more. Unfortunately, it can prove to be harder than one would imagine choosing which one of the two is better suited for your requirements because of their many similarities. It includes a whole list of comparable features, such as scaffolding, full-text search support, and more. Then there’s also the fact that both Symfony and Laravel come equipped with features to enable cross-platform app development, making it even harder to pick between the two. So, now it is time we see how they are different to help you make an informed decision for your web app development project.

Speed: In this context, Symfony makes use of a variety of strategic approaches to handle, sustain, and maintain the app’s speed. It enables developers to determine the rate of the entire app or just a single feature by bypassing features that are not essential to the app’s core function. Unfortunately, Laravel doesn’t get any such special provisions to help developers take care of the speed challenge, though it does deliver relevant version control feature that allows migrating the app in the future.
Database support: For data access, both Laravel as well as Symfony provide Object Relation Mapping (ORM). However, in the former, Eloquent is used to tend to the ORM, whereas in Symfony, Doctrine takes care of the ORM. First things first, ORM facilitates easier data manipulation with Eloquent and Doctrine. Now, the differences in this regard — Symfony may enable automatic database migration, but it needs simple definitions for every single field in the model. Laravel, on the other hand, may not offer automated migration, but it doesn’t necessitate defining areas in the database model either.
Forms and validators: This is the aspect where the difference between Laravel and Symfony becomes clear and evident. While Symfony needs a validator component to ratify objects against a specific group of rules, Laravel enables validation of certain inputs against a restricted rule.
While the above discussion may translate into you wanting to look for the Laravel web application development company, the fact remains that you must first carefully evaluate your requirements against the provisions of each one of the two PHP frameworks before making any decision.
