In most cases, the HSV color model gives a better result. When comparing
picture 8 with picture 1, 2 and 3, the histogram intersections of the RGB color
model are resp. 52\%, 66\% and 66\%. With the HSV color model, these
intersections are resp. 28\%, 61\% and 45\%.

\end{figure}
If we visually compare picture 8 with the pictures 1, 2 and 3, we can clearly
see that picture 2 shows more similarities (similar yellow color, similar size
and ratio of the object) than the other two pictures.

However, in the RGB model, there is no clear distinction in the histogram
intersections (52\%, 66\% and 66\%), while the HSV model gives picture 1 and 3
a much lower intersection percentage (picture 2 has 61\%, picture 1 has 28\%
and picture 3 has 45\%).
So, using the HSV color model does improve the results.
