Analysis of Failure Cases in Our Method: Addressing Limitations for Enhanced Performance

The failure cases of our method mainly encompass three types. Firstly, failure (a) arises when the hands cannot be detected. Secondly, failure (b) occurs when artifacts appear on the target person, resulting in the generation lacking the forearm and exhibiting misaligned legs. Lastly, failure (c) manifests as the generation failure when the target person image includes the presence of a third person. \n\nHowever, the occurrence of these failure cases does not render our method ineffective. Therefore, it is crucial to address and mitigate these issues in order to enhance the overall performance and reliability of our approach.
