Edge detection in Python

Edge detection is ubiquitous in animal vision and yet poorly understood. Canny edge detection on Polygonia c-album (Portugal, 2010) Great strides in artificial intelligence development during the last five years produced agents that are now commonplace at work and home. It is humbling to note that virtually all frontier large language models today trace back … Continue reading Edge detection in Python →

Object detection and tracking in Python

Over six months ago I decided to embark on a learning journey of image analysis using Python. After carefully reviewing various options I took a two-course offer from OpenCV.org for about US$479, chiefly because of i) the pivotal role of OpenCV as an open-source toolkit in computer vision, ii) the relevance of the course modules, and iii) the vast … Continue reading Object detection and tracking in Python →

Convolutional Neural Networks in R

Last time I promised to cover the graph-guided fused LASSO (GFLASSO) in a subsequent post. In the meantime, I wrote a GFLASSO R tutorial for DataCamp that you can freely access here, so give it a try! The plan here is to experiment with convolutional neural networks (CNNs), a form of deep learning. CNNs underlie … Continue reading Convolutional Neural Networks in R →
