Reconstruct

1

Reduce blurring by applying noise reduction (see method)

2

Reduce cupping by applying beam hardening correction (see method)

3

Increase contrast by stretching floating point range of fossil grey values

Render

4

Segment fossil from matrix by applying global threshold (Fig.3A)

5

Segment fossil form non-adjacent matrix using region grower tool (Fig. 3B)

6

Remove adjacent matrix with a masking tool (Fig.3C)

7

Repeat steps 4-7 to segment anatomical features (Fig. 3D)

8

Apply lighting and false colour to create virtual specimen see (Fig. 4)

9

Animate rendered 3D model using a keyframer (Fig. 6)

Store

10
