combining color segmentation with edge detection
Continuing the exploration of edge detection algorithms for the SRV-1 / SVS firmware, we finally had a chance to explore an earlier idea of combining color segmentation with edge detection as a possibly richer approach to feature extraction. Here are some preliminary results -
basic 16-color segmentation:
16-color segmentation combined with edge detection:
There results are very encouraging - scene features stand out much more strongly with the addition of edges. Note that for edge detection, we are still using just one horizontal and one vertical comparison (1x3) rather than a full 3x3 convolution kernel. The 3x3 approach didn't actually provide significantly better results and computation was a lot slower.
The discussion of this effort continues here -
"Surveyor Robotics Forum: new firmware with edge detect: srv-blackfin-101708"
Next step is to use this approach to begin building depth maps with the SVS.
