Illumination normalization for edge-based face recognition using the fusion of RGB normalization and gamma correction (2014)
Presentation / Conference Contribution

In this paper, an illumination normalization technique for edge-based face recognition on face images with non-uniform illumination conditions, is proposed. The proposed illumination normalization technique fuses the merits of color (Red, Green and B...

Face recognition via edge-based Gabor feature representation for plastic surgery-altered images (2014)
Journal Article

Plastic surgery procedures on the face introduce skin texture variations between images of the same person (intra-subject), thereby making the task of face recognition more difficult than in normal scenario. Usually, in contemporary face recognition... Read More about Face recognition via edge-based Gabor feature representation for plastic surgery-altered images.

A new watermarking technique for mammogram images copyright protection (2014)
Journal Article

Recent advances in technology have enabled the digitization of medical images for easy retrieval. However, the retrieval process of digital medical image makes the image prone to illegal distortions and reproduction. In this regards, the confidential...

Edge-based representation and recognition for surgically altered face images (2014)
Presentation / Conference Contribution

Basically, plastic surgery procedure introduces skin texture variations between images of the same person (intra-face) thereby making recognition more difficult than in normal scenario. Since the shape of significant face features such as eyes, nose,... Read More about Edge-based representation and recognition for surgically altered face images.

Measurement and time dispersion analysis of UWB channels for Infostation application in an outdoor recreation park (2014)
Presentation / Conference Contribution

In this paper the time dispersive analysis of a set of data obtained from the UWB channel measurement of an environment typical of the Infostation scenario in a recreation park is presented. The measurements were carried out in the frequency band of... Read More about Measurement and time dispersion analysis of UWB channels for Infostation application in an outdoor recreation park.
