Texture classification of the ultrasonic images of rotator cuff diseases based on radial basis function network
ABSTRACT This article studies the usages of texture analysis methods to classify ultrasonic rotator cuff images into the different disease groups that are normal, tendon inflammation, calcific tendonitis and tendon tear. The adopted texture analysis methods include the texture feature coding method, gray-level co-occurrence matrix, fractal dimension and texture spectrum. The texture features of the four methods are used to analyze the tissue characteristic of supraspinatus tendon. The mutual information feature selection and F-scoring feature ranking method are independently used to select powerful features from the four texture analysis methods. Furthermore, the trained radial basis function network is used to classify the test images into the ones of four disease group. Experimental results tested on 85 images reveal that the classification accuracy of proposed system can achieves 84%.
