Computer vision is a field in artificial intelligence based on giving machines an understanding of data from images, video frames, pixel manipulations, and others. In this article, we will look into four commonly used annotation tools for object detection/tracking. To demonstrate these, we will be annotating team players on the football pitch.
The following is an outline on what we will be looking into:

Object detection is a computer vision technique whose aim is to detect objects such as cars, buildings, and human beings, just to mention a few. The objects can generally be identified from either pictures or video feeds.
Compression involves processing an image to reduce its size so that it occupies less space. There are already codecs, such as JPEG and PNG, whose aim is to reduce image sizes. There are two types of image compression; lossy and lossless.
In lossless compression, one can retrieve the original image data, while in lossy compression one cannot. As a point of reference, PNG is lossless and JPEG is lossy.

With recent developments in big data, we’ve been given more access to high-dimensional data. Consequently, the performance of machine learning models has improved by a large margin.
On the other hand, there are significant noisy and useless features often collected or generated by different sensors and methods. These unneeded features not only influence a model’s accuracy, but they also can demand a lot of computational resources.

This will be a short and concise tutorial on how to build a facial recognition system with JavaScript, using faceapi.js built on Tensorflow.js; hence we won’t be interacting with Tensorflow.js directly.
This is what our final model output should look like
We want to build an ML system, that when given a specific input image, will tell us if a face in the input image is similar a face in our database. 😉
This write up is an excerpt from my recent research on transfer functions and machine learning operations. Throughout this post, I’ll basically be establishing the core principles of these two different concepts, and examine their relationship to each other.
I have always understood machine learning algorithms as a simple relationship between variable X and Y, where X is the input data and Y is the learning outcome. The general polynomial relationship between X and Y is bounded by the following function:

In this post, we’re going to learn about the most basic regressor in machine learning—linear regression. Specifically, we’re going to walk through the basics with a practical example in Python, and learn about applying feature engineering to the dataset we work with.
This is a two-part article, and this part encompasses the basics of feature engineering and regression. In part 2, we’ll discuss gradient descent (coding it from scratch), regularization, and other relevant concepts.

Heads up! This is an end-to-end series. In its three parts, I’m going to show you how to train, save, and deploy a recommender model. Specifically, you will understand how to get and process your data, build and train a neural network, package it in an application, and finally serve it over the internet for everyone to see and use.
Fast and Furious Image Loading (or FFImageLoading) in my opinion—and many others—is a must have in most Xamarin applications. If your application deals with a lot of images, it’s crucial to have this awesome library.
FFImageLoading supports a wide range of Platforms: Xamarin.iOS, Xamarin.Android, Xamarin.Forms, Xamarin.Mac / Xamarin.Tizen, and Windows (UWP, WinRT).

In my last blog on using the Room database in Android, we took a look at how to save/fetch our user data to/from a SQL database without having to write a lot of boilerplate code. If you haven’t read it yet, I would recommend that you do so before you go ahead with this one:
