Automated detection and classification of liver fibrosis stages using contourlet transform and nonlinear features
Computer Methods and Programs in Biomedicine(2018)
摘要
•Our proposed system classifies different stages of liver fibrosis using ultrasound images.•Two-dimensional contourlet transform and texture features are efficiently extracted.•The analysis of variance-based feature ranking technique is used.•The system achieved 91.46% accuracy with only four features using a probabilistic neural network classifier.
