| dc.description.abstract | The sharpness of the lesion boundary and the contrast between the lesion and the surrounding skin provide important diagnostic information in the assessment of pigmented skin lesions. This paper presents a new method for computing these parameters by employing an edge model based on a sigmoid function. For each radial profile of the lesion, optimal parameters are found by using an iterative least-squares method. The level and nature of variability of these parameters along the boundary will be correlated with lesion diagnosis in a future study. The method also returns the location equivalent to “zero-crossing” for each profile, thus producing a lesion outline. Additionally, the spread of the pigment beyond the zero-crossing point is computed, thus showing the lesion extent. | en |
