In this tutorial we'll look at how to achieve synchronized video streams with Python and OpenCV. One of the problems of video streaming is to transmit and acquire high-quality video signals with as little delay as possible. The ability to synchronize video streams is...
Raspberry Pi object detection and TensorFlow Lite
To improve performance on the Raspberry Pi, you can use the C++ language and optimized libraries to accelerate the computation speed of object detection models. This is what TensorFlow Lite offers. A good place to start is QEngineering. Hardware Raspberry Pi 4...
Object detection with Yolo on Raspberry Pi
It's possible to embed object recognition models like Yolo on a Raspberry Pi. Of course, because of its low performance compared with computers, performance is lower in terms of real-time recognition. However, it is perfectly possible to develop algorithms using...
Bluetooth communication with ESP32
In this tutorial, we'll learn how to activate, manage and test Bluetooth on an ESP32 using the Arduino programming language. Bluetooth is a wireless technology widely used for communication between electronic devices. It enables you to quickly transform your system...
Training a TensorFlow2 model with Keras
In this tutorial, we'll train a MobileNetV2 TensorFlow model with Keras so that it can be applied to our problem. We'll then be able to use it in real time to classify new images. For this tutorial, we assume that you have followed the previous tutorials: using a...
Object recognition with Yolo and OpenCV
In this tutorial, we'll look at how to perform object recognition with Yolo and OpenCV, using a neural network pre-trained with deep learning. We saw in a previous tutorial how to recognize simple shapes using computer vision. This method only works for certain...
Prepare an image bank for Model training
To prepare an image database for training a neural network in object recognition, you need to recognize the images in the database yourself. This means giving them a label and a recognition zone. This tutorial follows on from the article Creating an image bank....
Object recognition with TensorFlow and OpenCV
In this tutorial, we'll look at how to perform object recognition with TensorFlow and OpenCV, using a neural network pre-trained with deep learning. We saw in a previous tutorial how to recognise simple shapes using computer vision. This method only works for certain...
Lightweight Raspberry Pi image backup
We present here a method for making a light backup and restoring a Raspberry Pi. Creating a backup, an image of your Raspberry Pi, is essential in the event of SD card corruption or power failure. On Raspberry Pi and other single-board computers, the SD card often...
Creating an application with React Native and VSCode
In this tutorial, we'll look at how to program a smartphone application using React Native and VSCode. React Native is a powerful tool for creating cross-platform applications (Android, IOs) using the JavaScript language. Visual Studio Code is a code editor for...
