we can clearly see that the image formation model is the same. However, the rendering algorithm is very different. NeRFs are a continuous representation implicitly representing empty/occupied space; expensive random sampling is required to find the samples in Eq. 2 with consequent noise and computat...
with 𝜖ϵ being identically distributed observation noise. We implement a Gaussian process to realise this mapping. By definition, a Gaussian process can be defined as a continuous collection of random variables, any finite subset of which is normally distributed as a continuous multivariate distrib...
可以看出高斯效果好点,不过还是要根据不同的需求去做的。 使用cv2.GaussianBlur函数应用高斯滤波,详细用法请参考:OpenCc GaussianBlur方法 使用cv2.medianBlur函数应用中值模糊,详细用法请参考:OpenCV medianBlur方法 使用cv2.bilateralFilter函数应用双边滤波,详细用法请参考:OpenCV bilateralFilter方法...
