Face detection in colour images using fuzzy Hough transform

Novel,fast, accurate, and low complexity face localisation algorithm is presented. It is robust for hard scene conditions, such as complex background, different lighting, and face poses. It exploits spatial masking of face colour areas in normalised perceptually plausible tint-saturation-luminance (TSL) space where Canny filter is applied. Then,facial areas are approximated by ellipses of constrained proportions using fuzzy Hough transform on detected edges. Finally eye localisation technique is applied in Cr-Cb colour space in order to determine face pose, confirm face presence, and it enables us normalisation of face recognition.
