Image-guided velocity interpolation using a mask cube

A device comprising:

• a memory;
• and
• a processing unit that is arranged to perform operations including:
• generating a 3D array of velocities;
• generating a mask for the 3D array of velocities, wherein each value in the 3D array of velocities is associated with a corresponding value in the mask;
• calculating a 3D array of diffused velocities by applying structure oriented smoothing to the 3D array of velocities;
• calculating a diffused mask by applying the structure oriented smoothing to the mask;
• and
• calculating interpolated velocity values based on the 3D array of diffused velocities and the diffused mask.

A non-transitory computer-readable medium storing instructions executable by a computer system to perform operations comprising:

• generating a 3D array of velocities;
• generating a mask for the 3D array of velocities, wherein each value in the 3D array of velocities is associated with a corresponding value in the mask;
• calculating a 3D array of diffused velocities by applying structure oriented smoothing to the 3D array of velocities;
• calculating a diffused mask by applying the structure oriented smoothing to the mask;
• and
• calculating interpolated velocity values based on the 3D array of diffused velocities and the diffused mask.
