Conference Proceeding
Olisah, C., Adeleye, O., Smith, L., & Smith, M. (2022). A robust machine learning framework for diabetes prediction. In Proceedings of the Future Technologies Conference (FTC) 2021 (775-792). https://doi.org/10.1007/978-3-030-89880-9_58

Diabetes mellitus is a metabolic disorder characterized by hyperglycemia which results from the inadequacy of the body to secret and responds to insulin. If not properly managed or diagnosed on time, diabetes can pose a risk to vital body organs such... Read More about A robust machine learning framework for diabetes prediction.

Aesthetic surgery induced transformation face insensitive features: The medical and theoretical standpoint (2017)
Conference Proceeding
Olisah, C. C., Okpala, M., & Ikuesan, A. R. (2017). Aesthetic surgery induced transformation face insensitive features: The medical and theoretical standpoint. In 2017 IEEE AFRICON (391-396). https://doi.org/10.1109/afrcon.2017.8095514

The changes in facial appearance resulting from the effect of plastic surgery may manifest in the form of textural variations, and/or geometric variations with respect to the facial structural features such as eyes, nose, mouth, jaw, nose, brow, etc....

Recognizing surgically altered faces using local edge gradient Gabor magnitude pattern (2017)
Conference Proceeding
Olisah, C. C., & Ogedebe, P. (2017). Recognizing surgically altered faces using local edge gradient Gabor magnitude pattern. In 2016 Information Security for South Africa (ISSA) (114-120). https://doi.org/10.1109/issa.2016.7802937

For humans, every face is unique and can be recognized amongst similar faces. This is yet to be so for machines. Our assumption is that beneath the uncertain primitive visual features of face images are intrinsic structural patterns that uniquely dis...

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.
