Phase contrast images of stromal region of different stages of cervical pre-cancer were captured from tissuesections. A wavelet leader based multifractal analysis was performed on the phase contrast images to estimatemultifractal spectrum for each image. Wavelet leaders were calculated through discrete wavelet transform usingbi-orthogonal mother wavelets. The derived multifractal parameters, namely, width of singularity spectrumshows good discrimination between different grades of cervical pre-cancer.
