5.4 Context-driven Camera Switching
In the following experiments, we perform parameter sensitivity
analysis for context-driven camera switching and compare its performance
to a baseline switching solution.
Methodology.
Baseline Switching Scheme. We compare our adaptive contextaware
switching strategy (carsafe) to a static strategy (baseline)
that gives equal time to both cameras in a simple round robing
manner, but does not adjust to the environment .
Parameter Tuning. Figure 13 shows the precision and recall
for different parameter combinations for both carsafe and
baseline switching schemes. During this experiment we perform
a conventional grid parameter search with intervals of 1 sec
within a parameter range of 1 to 30 seconds, for each parameter.
The simulator provides both recall and precision values. Figure 13
shows that baseline performance is clustered at the bottom left
hand side of the graph, compared to the top right hand side clustering
for carsafe.
