This paper proposes a composite filter for noise reduction of image. To improve the image quality by reducing the noise in the liver ultrasound image, we tried to help the accurate image analysis. In the experiment, the top seven composite filters were selected by combining the Gaussian blur filter, the sharpening filter, and the median filter using the ATS-539 ultrasonic phantom, and applied to the ultrasound image in which this was done. As a result, it was found that the values of SNR, CNR and MSR all increased when the top seven composite filters were applied. In addition, PSNR of more than 30 dB, close to SSIM 1 showed that the image loss rate is small. Therefore, the appropriate application of the proposed composite filter in this research will be useful for accurate video reading and analysis.
