Conference Proceeding
Olisah, C., Sulong, G., Chude-Okonkwo, U. A. K., & Hashim, S. Z. M. (2014). Illumination normalization for edge-based face recognition using the fusion of RGB normalization and gamma correction. In 2013 IEEE International Conference on Signal and Image Processing Applications (412-416). https://doi.org/10.1109/ICSIPA.2013.6708042

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
Chude-Olisah, C. C., Sulong, G., Chude-Okonkwo, U. A. K., & Hashim, S. Z. M. (2014). Face recognition via edge-based Gabor feature representation for plastic surgery-altered images. EURASIP Journal on Advances in Signal Processing, 2014(1), Article 102. https://doi.org/10.1186/1687-6180-2014-102

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
Sulong, G., Hasan, H. R., Hajiabdollah, T., & Olisah, C. C. (2014). A new watermarking technique for mammogram images copyright protection. Life Science Journal, 11(5), 102-108. https://doi.org/10.7537/marslsj110514.14

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...

Measurement and time dispersion analysis of UWB channels for Infostation application in an outdoor recreation park. In 2013 7th International Conference on Signal Processing and Communication Systems (ICSPCS)https://doi.org/10.1109/icspcs.2013.6723911

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.

Edge-based representation and recognition for surgically altered face images (2014)
Conference Proceeding
Chude-Olisah, C. C., Sulong, G. B., Chude-Okonkwo, U. A. K., & Hashim, S. Z. M. (2014). Edge-based representation and recognition for surgically altered face images. In 2013, 7th International Conference on Signal Processing and Communication Systems (ICSPCS)https://doi.org/10.1109/icspcs.2013.6723974

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.
