the experimental results show that new smoothing algorithm can filter out the noise in the point data, preserve the feature well, prohibit the volume from…
实验结果显示,本文的光顺算法不但能够有效地去除噪声,抑制体积收缩,并对特征的保持效果也较为理想。
to filter out the noise and error arising out of various physical measurement processes and limitations of the acquisition technology, a gaussian weight is assigned to each point acquired.
首先,为了去除测量产生的噪声和误差,引入高斯核函数为每个采样点加权;
then the pixels polluted by noise were filtered accordingly. experiment proved that the method can filter out the noise effectively while keeping complete temperature information.
然后进行对噪声污染像素的针对性滤波,实验证明,达到了既能有效滤除噪声,又完整保留温度信息的目的。
