Loc8 testing

05/13/2018

I began testing the Loc8 software with images collected while working on my Master's Thesis. Many of these images contain traffic cones at certain places around the aircraft. Since Loc8 refers to their algorithms as the "Bloodhound Technique" I decided to call the images I'm looking for "Scent", and the images I'm searching "Targets". Using the viewer selection mode I selected a sample of colors present on the cones at the nose of the aircraft.

 Loc8 searched the 9 provided images for colors that matched the samples, and was able to locate cones in most other images.

Figure 2: Front view scent 1

In figure 2 we can see that Loc8 found two of the four cones,. In the bottom left corner below the image being displayed we can see "Image 6 of 7". This means that in 2 of the images no cone was found.

Another attempt was made with a larger sample of colors taken from the cones.

For some reason this larger sample prevented the program from finding the cone on the left side of the aircraft. Not entirely sure why this is, when it expanded the objects found in other images. Figure 4 shows the program finding a fuel cap on the left wing with scent 2 that it did not find with scent 1.

This software is clearly very capable, but has a bit of a learning curve that I will have to get through.
