摘要 通过利用小波变换对医学超声图像进行分解,研究其小波变换系数的均值、标准差、图像的能量等统计特征,为医学图像压缩编码和图像去噪进一步研究提供参考. The medical ultrasound image was decomposed with the wavelet transform.The statistical properties such as mean,variance and energy of the wavelet transform coefficients were studied.The analysis might guide the medical image compression coding and the image de-noising.
