If you’ve ever developed an iOS Vision app that process frames of a video buffer, you know that you need to be careful with your resources. You shouldn’t process each frame—i.e., where the user just moves the camera around.

In order to classify an image with high accuracy, you’ll need to capture a stable scene. This is crucial for apps that use Vision. In this tutorial, I’ll be diving into this problem and the solution Apple suggests.

Apple’s Core ML is a powerful machine learning framework with an easy-to-use drag-and-drop interface. And the latest iteration, Core ML 3, brought in lots of new layers and gave rise to updatable models.

In React Native apps, support for Scalable Vector Graphics (SVG) is provided by an open-source module called react-native-svg that’s maintained by the larger developer community.

Using SVG can enhance an app’s design when it comes to displaying different patterns. It can make a difference in how the look and feel of the app might appear to the end-user, as well how it is easy to edit the pattern built using SVG. SVG is mainly found on the web, and while they have similar uses to JPEG, PNG, and WebP image types, SVG is not resolution-dependent. Hence, the definition according to Wikipedia:

This article is part 4 of a series centered on hands-on approaches to feature selection techniques. If you’ve missed any of the other posts, I’d recommend checking them out:

Welcome back! In part 4 of our series, we’ll provide an overview of embedded methods for feature selection.

We learned from the previous article a method that integrates a machine learning algorithm into the feature selection process. Those wrapper methods provide a good way to ensure that the selected features are the best for a specific machine learning model.

Over the years, Apple has released some breakthrough features at its annual WWDC conference. In addition to the iOS community, developers all over the world keenly look forward to Apple’s annual conferences. It’s no wonder that figuring out which WWDC conference stood out from the rest is always a dilemma.

Some say WWDC 2019 was the best developer conference in years, due to the slew of new features and significant tools introduced. SwiftUI, a powerful new framework for building user interfaces, and major upgrades in the Core ML and Vision framework make it tricky to downplay Apple’s achievements in 2019 — and I won’t do that either.

In the last piece in this series on developing with Flutter, we looked at how we can implement [image labeling using ML Kit, which belongs to the Firebase family.

In this 7th installment of the series, we’ll keep working with ML Kit, this time focusing on implementing face detection. The application we build will be able to detect human faces in an image, like so:

Nowadays, lots of mobile applications like Office Lens and Genius Scan can turn a physical document into a digital one using only a phone—you actually no longer need to have a bulky, costly scanner.
