Edge conservation filters are widely preferred for the removal of medical images as they do not degrade the morphological edges during smoothing. Although the operational parameters of these filters have a crucial influence on their performance, the parameters are selected subjectively. Optimal values of the operating parameters can be selected objectively with the help of edge quality indexes. Available edge quality indices do not meet subjective quality ratings or are prone to noise level.
Magnetic resonance (MR) images filtered by anisotropic diffusion for different values of number of iterations are used as earth truth images. The PFOM is compared to existing edge quality indexes in terms of noise robustness and correlation with subjective fidelity ratings. PFOM exhibits a correlation of 0.9999 with the subjective edge quality score which is only 0.9802 for the Edge Preservation Index (PPE). Conclusions: The proposed index is robust to the noise level and useful for optimizing the performance of non-linear spatial filters.
