Effect of Edge-Preserving Adaptive Image Filter on Low-Contrast Detectability in CT Systems: Application of ROC Analysis
CT Systems ROC Analysis
2009/9/4
Objective. For the multislice CT (MSCT) systems with a larger number of detector rows, it is essential to employ dose-reduction techniques. As reported in previous studies, edge-preserving adaptive im...
In this paper we propose an on-line learning system for objectionable image filtering. Firstly, the system applies a robust skin detector to generate skin mask image, then features of color, skin text...
