Brief human action recognition literature survey of work published between 2014 and 2019.
Over the last couple of months, I have been going through a lot of literature about human action recognition using computer vision. In this post, I will share a brief survey of Human Action Recognition. …
The NFC Data Exchange Format (NDEF) is a standardized data format that can be used to exchange information between any compatible NFC device and another NFC device or tag. The data format consists of NDEF Messages and NDEF Records.
In this series of articles, I will explain how an NDEF…
In this short post, I will walk you through the steps for streaming a live camera feed from a DSLR connected to the Raspberry Pi. We will be using gphoto2 for interfacing with the camera, FFmpeg for encoding the video, and FFserver for hosting the feed on a local webserver.
Prerequisites
Hardware
In this short post, I will walk you through the steps for controlling and capturing pictures from a DSLR connected to the Raspberry Pi using a USB cable. There are numerous tutorials out there for this setup but I found them to be outdated to some extent. …
Recently while working on a project, I needed to install FFmpeg on a Raspberry Pi. I also required FFServer along with FFmpeg. There are two issues here, firstly a standard binary of FFMpeg is not available for Raspberry, and secondly, FFServer is no longer packaged along with FFmpeg. …
In this post, we will try to classify images from the Covid-19 Radiography Dataset[1] using a pre-trained ResNet-18 network. We will be using the PyTorch library for building our network.
Disclaimer: This model should be used only for learning purposes as Covid-19 diagnosis is an ongoing research topic.

In this post, we will see how to import data to the Neo4J database from CSV files.
Recently, I worked with Graph databases for the first time and was really amazed by the capabilities it offers. Initially, I struggled to find a good resource that guides beginners to import CSV…
Custom Data Generator, Layer, Loss function and Learning Rate Scheduler
In this post, I will demonstrate how you can use custom building blocks for your deep learning model. Specifically, we will see how to use custom data generators, custom Keras layer, custom loss function, and a custom learning rate scheduler.
Custom Data Generator
Tensorflow provides tf.keras.preprocessing.image.ImageDataGenerator (link) which is apt for most of…
Tensorflow 2.0 comes with a set of pre-defined ready to use datasets. It is quite easy to use and is often handy when you are just playing around with new models.
In this short post, I will show you how you can use a pre-defined Tensorflow Dataset.
Prerequisite
Make sure that…
In this post, I will explain how to use the Android Paged list with a boundary callback. The idea is to see an example where both the network and the local database is involved. We would be using Kotlin for the whole example.
Introduction
In this post, we will be using…
