An Intelligent Diagnosis Method of Brain MRI Tumor Segmentation Using Deep Convolutional Neural Network and SVM Algorithm

Table 2

The description of the adopted indices.

Index	Expression/description
True Positive (TP)	TP indicates that the model predicts a glioma region, and the doctor marks pixels that are also glioma regions
False Positive (FP)	FP means pixels predicted by the model as the glioma area are actually the background area
True Negative (TN)	TN indicates that the model predicted as the background area is actually the pixel of the background area
True Negative (TN)	FN means pixels predicted by the model as the background area are actually as the tumor area
