If your in-house mobile machine learning model gives you an advantage over your competitors, you’ll probably want to keep it private. Unfortunately, at the moment, Apple doesn’t offer any approaches to keep Core ML models private.
Anyone can get your .mlmodel file (or the compiled version mlmodelc) and reuse it in third party applications. In this article, you’ll learn a few strategies for protecting your Core ML models.
Are you looking for fast deep learning modeling? If so, Keras is going to be your natural choice. But there are so many deep learning frameworks available today, and the list is growing very fast—why choose Keras?
Keras has the capability and resources to run on top of popular deep learning libraries like TensorFlow, Theano, or CNTK. It also offers a relatively simple API that manages to also offer a lot of flexibility. This makes Keras easy to learn and easy to use. Isn’t that enough reason to start using Keras?
On the Snapchat Lens Explore page, hundreds of thousands of lenses are listed each day. Different than your carousel, on the Explore tab users can search and discover new lenses based off of keywords, the people they follow, and their recommended interests.
Every few months, some of Snapchat’s Lens Creators — official and not — will shift their designs to meet a new trend. This trend is usually reflected through popular TikTok videos, Instagram’s trending aesthetics, or a pop culture event. Currently, following the rise of sentimentality for the early 2000s, trends like maximalism and cyber-core have resurfaced, tackling the combination of old-school internet and the new wave of abstract-yet-useable Lens concepts to make some pretty interesting combinations.
LiDAR is a sensor currently changing the world. It is integrated in self-driving vehicles, autonomous drones, robots, satellites, rockets, and many more.
This sensor understands the world in 3D using laser beams and measuring the time it takes for the laser to come back. The output is a point cloud.
It’s a technology harder to understand than the camera because less people have access to it. I had access to it and today will help you understand how LiDAR detection works for self-driving cars.
OpenCV is a powerful tool for doing intensive operations in real-time, even for resource-limited mobile devices. Throughout a couple of tutorials, we’re going to create an Android app that applies various effects over images.
In part 1, horizontal and vertical image stitching is discussed to merge 2 or more images.
In part 2, the cartoon effect is applied to a single image.

Not every app requires us to consider a global customer base. But if you have plans to include support for international users in your app, you’ll need internationalization in your React Native app. Using react-native-localize, your app can detect the operating system or the device language and support multiple languages.

Images add another dimension to a mobile app. User-generated images amplify that.
If you’re building a React Native app, how do you give your users the ability to upload images? React Native has polyfills for many web APIs — to do image uploading we’ll be using the fetch API.
Before we can actually start uploading images, we’ll to create two projects:
In a previous tutorial, I introduced the Kivy Python framework as a tool to run NumPy (Numerical Python) on Android. As a brief refresher, Kivy is a cross-platform framework for building natural user interfaces (NUIs). It’s very simple to learn and then use iteratively. The same code, unchanged, can run on Linux, Windows, Mac, iOS, and Android.

Have you ever wanted to make your own augmented reality app, but don’t know where to start? Or, are you just interested in AR technology more broadly?
In this series, we’ll demonstrate how to use Unity’s game engine to make a small AR app that can demonstrate important principles of the technology. To do so, we’ll dive deep in to Unity’s AR Foundation framework.

React Native, when used with Expo as a toolchain, eases the common pain points in managing iOS and Android applications. After saying that, I realized that there’s a delight in using this ever-growing open source mobile application framework.
Expo has gained a lot of credibility as a framework that provides collective solutions for building React Native applications by lowering the time and effort of developers using it. They’re continuing to enhance it from time to time to keep up with the latest changes in React Native community. That said, Expo SDK33 is a blast.
