Image, video or audio filtering before biometric recognition |
摘要 |
The present invention relates generally to pre-processing images, audio and/or video to improve biometric analysis from such. In one implementation, a method is provided including: receiving a color digital image including a representation of a human subject; converting the color digital image into grayscale values; transforming at least one representation of the converted color image; analyzing the transformed, converted color image to identify artifacts; if artifacts are found, processing the color digital image to reduce the artifacts; and providing the processed digital image to a biometric system. Other implementations are provided as well. |
