TRANSCRIPT
• Gives where surface is convex, saddle, or flat• Indicates surface shape at a pixel
Gaussian Curvature
The average of the principal curvatures If zero, minimal surface
Noise
Norm in Y directionNorm in X direction
Norm in Z direction
Gaussian Curvature
Mean Curvature
Normal and Curvatures
• 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
Fixing Noise
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
