• 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

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

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
