Abstract :
In this paper, we propose an effective pre-processing method of CT brain images to provide consistent feature for content-based medical image retrieval. The key steps in pre-processing include cutting out background region, using ellipse to correct lean imaging angle, and normalization. We take vast CT brain images as experimental data to evaluate the method. Experimental results show the effect of pre-processing.
