Abstract
We had human subjects perform a one-out-of-six class action
recognition task from video stimuli while undergoing functional magnetic
resonance imaging (fMRI). Support-vector machines (SVMs) were
trained on the recovered brain scans to classify actions observed during
imaging, yielding average classification accuracy of 69.73% when tested
on scans from the same subject and of 34.80% when tested on scans
from different subjects. An apples-to-apples comparison was performed
with all publicly available software that implements state-of-the-art action
recognition on the same video corpus with the same cross-validation
regimen and same partitioning into training and test sets, yielding classification
accuracies between 31.25% and 52.34%. This indicates that
one can read people’s minds better than state-of-the-art computer-vision
methods can perform action recognition.
