Luminance Pre - processing For Facial Composite System
Abstract The variation that arises in generated composite images affects the overall image when a feature from a very dark face is superimposed on a very light face or vice versa . The minimal edge smoothing is not always sufficient to blend this difference . So , the luminance pre - processing appr...

Summary: | Abstract The variation that arises in generated composite images affects the overall image when a feature from a very dark face is superimposed on a very light face or vice versa . The minimal edge smoothing is not always sufficient to blend this difference . So , the luminance pre - processing approach is utilized in a way that the resulted composite image seems realistic to most human observers . Face parts are transformed into correspondence background composite image before compositing process . This is achieved by employing the skin color information of the YIQ color space . The results obtained by applying luminance pre - processing approach show better improvement compared with minimal edge smoothing approach . |
