This paper investigates new approaches for improving the conventional palmprint authentication performance by integrating color information. We firstly propose a new approach for image level combination of multiple color components to generate more reliable palmprint representation than the conventional gray level representation. This investigation is motivated to develop more robust palmprint representation...
Palmprint identification has emerged as one of the popular and promising biométrie modalities for forensic and commercial applications. In recent years the contactless system emerges as a viable option to address hygienic issues and improve the user acceptance. The presence of significant scale, rotation, occlusion and translation variations in the contactless palmprint images requires the feature...
In this work we have applied femtosecond pump-probe microscopy to study the regime of strong excitation, previously not reported on with imaging techniques. The ability of this technique to simultaneously measure reflectivity changes with fs temporal resolution at locations of strong and weak excitation enables a direct comparison of mechanisms occurring in adjacent regions. For the experiments we...
