Face detection and tracking in images have become an important concept for the researchers in the field of Digital Image Processing.Image enhancement refers to the improvement of inner details of image for visual perception.This paper combines these two concepts, using fuzzy logic based enhancement techniques to detect face in low contrast images.After fuzzy enhancement of the input image next step is detection and segmentation of the skin region.Enhancement is based on Fuzzy Intensification Operator (FIO) and Brightness Preserving Dynamic Fuzzy Histogram Equalization (BPDFHE).The detected faces are tracked by enclosing them using two dimensional regions.Comparative study of the enhancement algorithms on face tracking is carried out on the parameters like quality factor, segmentation error, and overlap area.
