Accuracy from different k of k-NN. As shown in the figure, the blue line that is the highest recognition rate denotes the recognition rate of combined features. The red line is the recognition rate of color features. The green line is the recognition rate of texture features and the purple line, i.e., the recognition rate of shape features, denotes the lowest recognition rate
