Fig. 5.

Percentage of correctly identified bystander activities (lower percentage means greater improvement in bystander privacy) using each obfuscation method. Some obfuscation methods (such as blur and edge) fail to obfuscate bystander activities when the intensity or the amount of motion is high (Exercise and Fight in a) but succeed in obfuscating the activity when it is low in intensity (b).
