Generally, there is a tradeoff between quality and computational workload required to obtain that quality. In this paper, we focus on practical issues in implementing a pig activity monitoring system. We first propose a method for evaluating the quality-workload tradeoff in the activity monitoring application. Then, we derive the cost-effective solution within the acceptable range of quality for the activity monitoring application. Based on the experiments with the video monitoring data obtained from a pig farm, our method can derive the cost-effective resolution size and frame rate without degrading the accuracy significantly.
