Preventive Measures for Facial Distortion and Color Discrepancy Problems
Facial distortion and uneven color are common problems with AI face replacement and can be effectively prevented by the following methods:
- Color balance preprocessing: Use an app like Snapseed to get the white balance of both photos to be similar (focus on the forehead and cheek area)
- Light Simulation: If the target photo is side-lit, add a similarly oriented light effect to the face clip in Photoshop
- Key point checking: Observe the automatically generated facial feature points (especially the corner of the eyes and mouth) after uploading, and manually fine-tune the misaligned points
- Resolution Matching: The difference in resolution between the two photos should not be more than two times (e.g., 1200 x 1800 for target image and at least 600 x 900 for source image).
- format conversionConvert PNG format to high quality JPEG (quality 90% or higher) to reduce the problem of color gradation faults.
If distortions have been generated, try multiple face changes (3-5) to allow the AI to self-correct, or use the platform's "Manual Repair" tool to adjust the anomalous areas individually.
