  • One threshold, calculate the sen and 1-speficity of one image, do the same for another image, get another sen and 1-speficity points, take average - from all images of the database> One average ROC points--
  • Another threshold, calculate the sen and 1-speficity of one image, do the same for another image, get another sen and 1-speficity points, take average - from all image of the database> another average ROC points--
  • soon...ROC curve..
