Comparative analysis of selected facial recognition algorithms

Systems and applications embedded with facial detection and recognition capabilities are founded on the notion that there are differences in face structures among individuals, and as such, we can perform face-matching using the facial symmetry. A widely used application of facial detection and recognition is in security. It is important that the images be processed correctly for computer-based facial recognition, hence, the usage of efficient, cost-effective algorithms and a robust database. This research work puts these measures into consideration and attempts to determine a cost-effective and reliable algorithm out of three algorithms examined.

Pillars of Effective and Efficient Energy Systems in Nigeria

Nigeria is posed with a myriad of challenges to achieving efficient energy systems; the colossal collective demand for sufficient electricity for approximately 200 million is a concern. Another challenge is the mismanagement of Nigeria’s abundant resources, by individuals and by groups. It has withheld us, for decades, from making the bold and rapid progress which ought to have made for the energy system. This report explores the concept of an energy system in Nigeria perspective and progresses

SURGICAL COMPLICATIONS FROM LOCAL HERBAL PRACTITIONERS: REPORT OF FIVE CASES

SUMMARYOver a 12-month period, five patients (out of a total of 72) with serious complications resulting fromuse of herbs by traditional healers were seen at the surgical unit of Olabisi Onabanjo UniversityTeaching Hospital, Sagamu, Nigeria. The age range was one and a half to five years with a meanage of 23.4 ± SD years and a male to female ratio of 3:2. All the cases were misdiagnosed andmismanaged and ended up with various complications. Such as penile amputations, digital necrosis,upper and lower limb gangrene as well a severe sepsis among others. Ignorance, cultural beliefsand attitudes, delusion, poverty and inaccessibility to orthodox medical practice were some of thefactors responsible for the patronage of traditional healers
