Face Segmentation/Detection

Before the middle 90’s, the research attention was only focused on single-face segmentation. The approaches included:

During the past ten years, considerable progress has been made in multi-face recognition area, includes:

  • Example-based learning approach by Sung and Poggio (1994).
  • The neural network approach by Rowley et al. (1998).
  • Support vector machine (SVM) by Osuna et al. (1997).

Neural network (NN)

  • Kanade et al. first proposed an NN-based approach in 1996.
  • Although NN have received significant attention in many research areas, few applications were successful.
  • It’s easy to train a neural network with samples which contain faces, but it is much harder to train a neural network with samples which do not.
  • The number of “non-face” simples are just too large.
  • Neural network-based filter. A small filter window is used to scan through all portions of the image, and to detect whether a face exists in each window.
  • Merging overlapping detections and arbitration. By setting a small threshold, many false detections can be eliminated.
