             abstract = "The digital image segmentation challenge has demanded the 
                         development of a plethora of methods and approaches. A quite 
                         simple approach, the thresholding, has still been intensively 
                         applied mainly for real-time vision applications. However, the 
                         threshold criteria often depend on entropic or statistical image 
                         features. This work searches a relationship between these features 
                         and subjective human threshold decisions. Then, an image 
                         thresholding model based on these subjective decisions and global 
                         statistical features was developed by training a Radial Basis 
                         Functions Network (RBFN). This work also compares the automatic 
                         thresholding methods to the human responses. Furthermore, the 
                         RBFN-modeled answers were compared to the automatic thresholding. 
                         The results show that entropic-based method was closer to 
                         RBFN-modeled thresholding than variance-based method. It was also
