Gaussian Curvature
• Gives where surface is convex, saddle, or flat
• Indicates surface shape at a pixel


The average of the principal curvatures
If zero, minimal surface
Noise
Normal and Curvatures
Norm in Z direction
Norm in X direction
Norm in Y direction
Mean Curvature
Gaussian Curvature
Fixing Noise
• Use the median to smooth
• Save images in lossless format (such as .png)
• Changing the range of values from 0 to 255 to
0 to 4000
– Allows more detail to be maintain
Gaussian Smoothed
Median Smoothed
Testing
• Extracted data
• Made annotations
• Trained and Tested
Problems
• Kinect Studio does not work on my computer
• RGB and depth images are not in sync
• Everything breaks
