    Assessment of a Novel Trainable Algorithm for Automated Segmentation of Multiple Islet Images.

  • Original language description

    Accurate sampling of islet graft suspension is confounded by the islet size heterogeneity. Assessment of multiple samples is advisable. Current islet counting methods remain time- and labour-intensive. We tested precision of automated assessment of multiple islet images by a simple learning algorithm. We generated the ground truth upon which a trainable algorithm was developed. The ground truth consisted of 12 islet images manually segmented in triplicates by four experienced operators using the gray-level thresholding. Next, training of Linear Perceptron algorithm (features = RGB) on individual images generated automatic classifiers, which in turn were used to assess islet images (dithizone-stained human islets with 40% exocrine tissue). The areas assigned to individual islets were converted to the islet equivalents (IE) using extended Ricordi table, d=2sqrt(area/ pi). The first twelve images were segmented in triplicates by four experienced operators using manual thresholding. The co
