A photogrammetric investigation of facial variation in Tanzanian and British populations

Abstract

The research topic involved an investigation of the facial characteristics of subjects from Great Britain and Tanzania. The methodology used was photogrammetry, which is indirect anthropometry using standardized photographs of the face. The material is presented in the following way. In Chapter One there is a brief description of the development of this study and a statement of the aims and objectives. This is followed by brief histories of the development of photogrammetry and of the study of the face. Chapter Two contains a description of the population samples from both Tanzania and Great Britain including their origins and numbers. The tribes of Tanzania are also described with their geographical locations and relationships with one another. This is followed in Chapter Three by a description of the methodology used in this investigation and a detailed account of the landmarks used and of the measurements taken. Chapter Four contains an account of the various sources of error which may have occurred in this study, methods taken to reduce these and other methods which could have been used to minimize error. In Chapter Five the various forms of statistical analysis is described. The indices computed, descriptive statistics, univariate and multivariato analyses are explained. The results obtained are set out in Chapter Six and discussed with reference to the two populations studied and various sub-groups. In Chapter Seven various theories of facial proportion and beauty are described. Some are selected for testing and the method used is explained. The sample of models and results obtained are described. Chapter Eight contains the conclusions of the investigation with a comparison of other researchers work and suggestions for further study.
