Teaching Mask R-CNN to measure something 30 pixels long
How we built CiliAI with two standard Mask R-CNN models and a handful of small-object tricks, and what I would do differently next time.
Spotting fake vaccines with black tape, a phone and two models
Fake vaccines leave different drying patterns than real ones. How we turned that into a two-model AI pipeline on 380 phone photos, and why I don't fully trust our 100%.
A timer to capture images from a webcam with OpenCV
We will build a script that takes images from a camera stream, with a delay between them, at a given width in pixels and for a given duration. The images can come from a webcam or a video.
Facial landmark detection with Dlib, OpenCV and Python
Finding faces in photos or videos is very cool, but it isn't enough information to build powerful applications. We need more information about the person's face, like its position, whether the mouth is open or closed, whether the eyes are open or closed, and so on.
