Face Liveness Detection Returns Low Confidence Scores in Bright Sunlight. #243

Description

@sothon19931

Face Liveness Detection yields significantly lower confidence scores (<80%) in environments with bright sunlight, despite achieving near-perfect scores (99.99%) in normal indoor lighting. This behavior appears to result from overexposure or glare interfering with the camera input, reducing the model’s ability to assess liveness accurately.

Expected behavior
Confidence scores should remain consistently high (>90%) across varying lighting conditions. Alternatively, the SDK should guide users to adjust their environment (e.g., move to shade or avoid backlighting) to improve detection reliability.
