Embodiment Construction
[0026] Such as figure 1 As shown, this real-time three-dimensional image smoothing method based on a graphics processor includes the following steps in turn:
[0027] (1) Send the three-dimensional image data to be processed to a graphics processing unit (GPU);
[0028] The three-dimensional image data processed by this smoothing method is the three-dimensional image texture data obtained by sampling after three-dimensional image reconstruction, and the three-dimensional image texture data is transmitted to the rendering pipeline in the graphics processing unit (GPU) by the central processing unit (CPU) through the OpenGL interface. , to the programmable fragment handler;
[0029] (2) Find the coordinates of each relevant point 2 around the current pixel point to be processed;
[0030] Such as figure 2 As shown, in the three-dimensional image texture data, the current pixel point 1 to be processed (referred to as the current point 1, figure 2 The relevant points of the h...
