Applying this entropie thresholding algorithm to human liver CT image, the result of segmentation is satisfying.
应用于肝脏CT图象,获得了较为理想的结果。
And then, establish the adaptive thresholding algorithm. Thus, we get a new adaptive threshold denoising method fit for coherent noise.
并在此基础上确定了自适应阈值计算方法,建立了新的阈值去噪法,可用于去除相干噪声。
Therefore, when applying a thresholding algorithm to an image, we generally assume that the background and target in that image occupy different gray level zone.
传统的阈值化算法仅仅使用像素点的灰度级信息,因而要求图像中的目标和背景在灰度级上是可分的。
