Automation:● Raspberry Pi 2 + Camera +
IR.● IR Sensor controls image
capture.● 5 sec. sample interval.● Images are queued for eval.● Accepted images uploaded
to Instagram.● Web server displays progress
and sets # tags.● TODO: Robust Geotagging.
● Uses a sliding window over the captured image.● Histogram of Oriented Gradients (HOG) forms the
low-level features.● Gradients fed into a Support Vector Machine (SVM)
machine learning algorithm.● Binary classify combinations of gradients →
detector.● Identifies the number of faces in each image.● Must be trained on a dataset of images that have
cat faces at similar image distance to the booth.● Trained 272, tested 1407 images, recall = 0.504.
Cat Face Recognition:
“Why must I feel like that? Why must I map the cat? Nothin’ but the HOG in me!”(apologies to George Clinton)
