Operationalizing Aby Warburg’s Atlas of images

Franco Moretti presents collaborative project (with Leonardo Impett) on computational approaches to Aby Warburg’s image atlas. Formulating pathos, faces are irrelevant. Clarity is not option, it’s a constraint. A strange encounter of qualitative and quantitative …

Accessorize to a crime

A team of researchers from Pittsburgh’s Carnegie Mellon University have created sets of eyeglasses that can prevent wearers from being identified by facial recognition systems, or even fool the technology into identifying them as completely unrelated individuals. In their paper, Accessorize to a Crime: Real and Stealthy Attacks on State-of-the-Art Face Recognition, presented at the […]

Green Mamba

Tensorflow, an open source library for Machine Learning developed by Google, comes with a demo program that labels images. The output of the program contains the labels (or class names) and their scores. The score represents the probability of the image to belong to a certain class. green mamba (score = 0.43074) vine snake (score […]

The princess and the pea

"Edmund Dulac – Princess and pea" by Edmund Dulac – Gutenberg.org: Stories from Hans Andersen, with illustrations by Edmund Dulac, London, Hodder & Stoughton, Ltd., 1911.. Via Wikipedia. Trying to come to grips with how a visual search engine works, I worked my way up to Chapter 7 of Programming Computer Vision: Searching Images. The […]

Homunculus argument

Original work: Jennifer Garcia,, Derivative work: Pbroks13, and Was a bee. CC BY-SA 2.5-2.0-1.0 One may explain (human) vision by noting that light from the outside world forms an image on the retinas in the eyes and something (or someone) in the brain looks at these images as if they are images on a movie […]

“One Millisecond Face Alignment with an Ensemble of Regression Trees”

This paper addresses the problem of Face Alignment for a single image. We show how an ensemble of regression trees can be used to estimate the face’s landmark positions directly from a sparse subset of pixel intensities, achieving super-realtime performance with high quality predictions. We present a general framework based on gradient boosting for learning […]
