    Real time face detection in C++ using Haar Cascade on OpenCV

    March 2, 2020 - By Praveen Nair

    I was using mostly Python to experiment AI/ML until recently but now it is time to find ways to improve the performance by making use of all the possible resources such as GPU, and including experimental change of language to C++. Here is the sample code I ported from simple Python face detection (not recognition) Hello-World program, and thought to bookmark for future. This uses Haar Cascade machine learning algorithm and you can read more about it here. Definitely, compared to Python code I feel there is some improvement in the performance, which I will publish the benchmarks later in…

    December 20, 2019 - By Praveen Nair

    Coders, have you ever wished if you get preview of source code while you are in Windows Explorer? Yes it is possible. You might know already that there is a “Preview Pane” feature present. According to a file’s Content Type the preview will be shown at the right side of the window.

    Whitepaper on Principles of container-based application design by Red Hat

    October 28, 2019 - By Praveen Nair

    Good read – https://www.redhat.com/en/resources/cloud-native-container-design-whitepaper “Cloud-native” is a term used to describe applications designed specifically to run on a cloud-based infrastructure. Typically, cloud-native applications are developed as loosely coupled microservices running in containers managed by platforms. These applications anticipate failure, and they run and scale reliably even when their underlying infrastructure is experiencing outages. To offer such capabilities, cloud-native platforms impose a set of contracts and constraints on the applications running on them. These contracts ensure that the applications conform to certain constraints and allow the platforms to automate the management of the containerized applications.
