Remote face detection system with OpenCV and Twilio

Fritz Sep 15, 2023

Revamp that old security camera you have in your backyard — the one that doesn’t even record images! Security systems too costly? Get working on build your own with Twilio and OpenCV !

One of the largest boons of technology has been how, with time, advanced camera and surveillance systems have become so widely accessible. Twilio today has democratized communications channels like voice, text, chat, video, and email by virtualizing the world’s comms infrastructure through APIs that are simple enough for any developer to use, yet robust enough to power the world’s most demanding applications.

Build and deploy an image classification API with NodeJS, Express, and Tensorflow.js MobileNet

Fritz Sep 14, 2023

Articles

Today, we’re going to be building a RESTFUL API that takes in an image and make predictions using a TensorFlow MobileNet pre-trained model.

TensorFlow.js has many pre-trained models that can be used in projects out of the box. This saves developers the task of training a model from scratch. Here we’re going to explore the MobileNet pre-trained architecture

Hyperparameter Optimization With Genetic Algorithms In Kotlin

Fritz Sep 14, 2023

Articles

Genetic Algorithms (GAs) are a subset of Evolutionary Algorithms, which use mechanisms inspired by nature such as mutation, evolution, reproduction, etc. In spite of using advanced math, these algorithms work on principles which are derived from nature. Growth of an organism in its environment and its interaction with other beings in that environment can be modeled with simple mathematical expressions.

Articles

Machine learning tech is being integrated into mobile applications more and more today. Its integration helps optimize overall performance and can add significant functionality to an app’s experience. And over time, ML models can learn and improve from user interactions, making these experiences super intuitive and intelligent.

Here, we’re going to continue working with this technology in the Flutter ecosystem. Check out my previous post on ML in Flutter for more:

Scan Barcodes on Android Using Google’s On-Device ML Kit

Fritz Sep 14, 2023

Articles

Google’s on-device ML Kit recently introduced another API for barcode scanning. It can read and scan almost a dozen different types of barcodes including Codabar, Code 39, Code 93, EAN-8, EAN-13, QR code, PDF417, and more.

The barcode scanning API also tells you the scanned format and it will automatically detect the formats. The other main feature of this API is that you can use it in your application without a network connection and it will support the different orientation.
