How does it work?

The Feng-GUI heatmap is a composition of several algorithms from neuro-science studies of Natural Vision Processing, Computational Attention, eye-tracking sessions, perception and cognition of humans.
Or in English: "What people are looking at?"

Here are some of the visual features that are analyzed in an image.

In videos, Feng-GUI analyzes some more features,
such as: flicker and direction and velocity of motion between frames.

How accurate is it?

Feng-GUI attention map reaches over 80% of AOI (Areas of interest) similarities to Eye and Mouse Tracking.

The algorithms behind Feng-GUI combine few decades of natural vision processing research. We compare and measure the results with eye-tracking sessions.

At the latest comparison benchmark, we used 90 images of advertisements, natural scenes and web sites. For each image, 40 different users provided their fixation points, during 15 seconds of observation.
