Number of frames with issues in each camera view based on each method.

• The percentage of failures in each video. Values are expressed as percentages based on a total of 180 frames. Each graph shows the percentage of frames where lower-limb keypoints were not identified fully. Each colour represents the different camera positions.

• Normalized lateral trunk lean angle. (A) Transtibial and (B) Transfemoral amputee. Each colour represents the pose estimation used: OpenPose (blue) and the zero-shot method (red). Positive angles indicate trunk lean to the ipsilateral side, and negative angles indicate trunk lean to the contralateral side.

• Different case examples. (A) In the original image, the left limb is positioned in front. However, upon generating the synthetic image, the left leg was positioned backward, and this discrepancy persisted after the application of OpenPose, where the dark blue line represents the left leg. (B) Case example where the generation of the synthetic image fails to change the prosthetic limb to an intact limb. (C). Case example where the generation of the synthetic image successfully changes the prosthetic limb to an intact limb.

• Normalized kinematics results for transfemoral. Top and bottom rows represent hip, knee, and ankle kinematics, respectively, on the left (blue; intact) and right (red; prosthetic) limb. (A) Kinematics comparing the ground truth (solid line) and OpenPose (dotted line). (B) Kinematics comparing the ground truth (solid line) and zero-shot method (dotted line). Positive hip and knee joint angles indicate flexion, negative angles indicate extension. Positive ankle joint angles indicate dorsiflexion, negative angles indicate plantarflexion. Some key differences in kinematics between the prosthetic and intact limbs are marked by arrows
