YEF∗Real-Time Object Detection
Yotam Abramson, Bruno Steux · 2004
We present an improvement to the object detection scheme of Viola and Jones [5], using the example of face detection. We present a new kind of visual features, which is based on sampling individual pixels within the examined sub-window, instead of comparing the sums of pixel values in rectangular regions. Our features are faster and do not demand the preparation of an integral image, nor variance-normalization of each sub-window. The result is an improved system which detects faces in quarter-PAL images in only 9 millisecond per image on a 2.4GHz pentium
