A brief history of my popular Github repository and why you should create something similar I maintain the popular Github repository satellite-image-deep-learning. This post provides the brief history of this repository, how I find material, and why you should create something similar. History When and why did I start this repository? I started this repository in April 2018 whilst I was working at Surrey Satellites. The…

Earth — a marvelous blue marble in the vastness of space is the only known place in the Universe that supports life. Our planet has witnessed multiple phases, of destruction and restoration alike, and has emerged triumphant on numerous occasions. But, at present, we stand at the cusp of an…

Researchers at the University of Maryland, College Park and NASA’s Goddard Space Flight Center in Greenbelt, Maryland, looked at the possibility of using a forest’s acoustics as a low-cost way to assess its health. Beginning in 2016, this study was directed by Danielle Rappaport, a doctorate candidate at the University…

Get up to speed with this versatile technique for labelling pixel regions in an image Image segmentation is a very versatile technique which enables the identification of targets which range in size from a small cluster of pixels up to targets that fill an entire image. This post introduces segmentation and clarifies the different types of segmentation (semantic, instance and panoptic). It then discusses image…

Introduction to Transformers and why you should care The Transformer is a neural network architecture first published in a 2017 paper titled Attention Is All You Need by researchers at Google. Transformers learn context by tracking relationships in sequential data using a technique called attention. Transformers are replacing CNN’s and RNN’s in many applications and have come to…

What is image classification, which models are used and how to approach your first project You may already be familiar with image classification from seeing the numerous cats vs dogs image classification tutorials on the internet. Image classification is therefore the task of assigning one (or more) labels to an entire image. Note however that the term ‘classification’ can mean different things to different people…

This significant new dataset raises the bar for documentation quality A new dataset called the WorldStrat dataset was recently announced on Twitter by Julien Cornebise, Ivan Orsolic, and Freddie Kalaitzis. The dataset raises the bar in documentation quality of a dataset and the release includes a paper on ArXiv, code on Github, and the dataset itself on both Zenodo and…
