People Recognition in Image Sequences by Supervised Learning

摘要

We describe a system that learns from examples to recognize people in images taken indoors. Images of people are represented by color-based and shape-based features. Recognition is carried out through combinations of Support Vector Machine classi- ers (SVMs). Di erent types of multiclass strategies based on SVMs are explored and compared to k-Nearest Neighbors classi ers (kNNs). The system works in real time and shows high performance rates for people recognition throughout one day.
