This study introduces a novel computer-aided diagnostic method for skin tumors using high-resolution skin surface profiles. The system accurately distinguishes malignant melanomas from nevocytic nevi, achieving a 97.7% classification performance.

Area of Science:

  • Dermatology
  • Computer Science
  • Medical Imaging

Background:

  • Accurate and early diagnosis of skin tumors is crucial in dermatology.
  • Traditional diagnostic methods can be subjective and time-consuming.
  • Automated systems can improve diagnostic efficiency and accuracy.

Purpose of the Study:

  • To develop and evaluate a computer-supported system for the automated diagnosis of skin tumors.
  • To analyze high-resolution skin surface profiles for distinguishing malignant melanomas and nevocytic nevi.
  • To optimize feature selection and neural network classification for improved diagnostic performance.

Main Methods:

  • Extraction of texture, Fourier, and fractal features from 2D skin surface profiles.
  • Application of feature selection algorithms, including genetic algorithms, to identify optimal feature subsets.
