Before revision:  Then, we present a CNN to obtain deep feature representation corresponding to each MRI modality ( T1 and T2). As the final step, we employ canonical correlation analysis (CCA) to perform a fusion operation at the feature level, leading to discriminative canonical correlation features.
After revision:  Then, we present a CNN to obtain deep feature representation corresponding to each MRI modality ( T1-weighted and T2-weighted). At the final step, we employ canonical correlation analysis (CCA) to perform a fusion operation at the feature level, leading to discriminative canonical correlation features.
