Combined CNN and Pixel Feature Image for Fatty Liver Ultrasound Image Classification

Figure 3

Example of generating image patches through the annotations of the ultrasonic liver images. (a) An ultrasonic image of normal liver. (b) An ultrasonic image of severe fatty liver. In the normal liver, the echo at the rear of the liver is obvious (marked by five blue arrows in (a)). When a large amount of fat particles is contained in the liver, the liver ultrasonic image turns white and the echo attenuation is serious (marked by two blue arrows in (b)).
