Biomedical Imaging Modality Classification Using Combined Visual Features and Textual Terms

Figure 6

The compared recognition rates with different features using three types of similarity measures: Euclidean distance (𝐿₂ distance), 𝐿₁ distance, and 𝜒² distance. Gray hist, variance, edge hist and color hist represent the histogram of gray, variance, edge, and color, respectively; BOF and textual mean the BOF and textual features.
