This paper introduces human-face recognition using edge-based rasterstereography, a biometric identification technique employing pattern recognition, which has the potential to be used as identification-based-security system. A raster grid was projected on human face, distortions of which were used to extract curvature information — unique for a face (principal identification and recognition criterion). This information, in coördinate form, was processed by image-processing algorithms. A modified-raster grid was constructed and tested. The modification, mainly, consisted of use of green dots instead of conventional screen composed of stacked squares, which gave acceptable results for green color. Registration, identification and verification were the three phases of face-recognition system proposed by the authors. In the first step, subject’s face was captured using a digital camera and stored in the system database. In the second one, the registered face was compared with all the stored faces in the database. The verification phase consisted of comparing the identified face with own stored template. Once the facial image passed these three stages, the face was recognized as the one belonging to a particular individual. Our face-recognition system correctly recognized 190 out of 200 human faces during test runs. This algorithm was computationally efficient and effective. The edge-based-rasterstereographic-face-recognition system seemed to be suitable for identification and security purposes as time and cost-saving mechanism. Full Text PDF

J30: A Method to Compute Growth-and-Obesity Profiles of Children of Still-Growing Parents

This work presents the method of computing growth-and-obesity profiles of children of still-growing parents (under-21 father and under-19 mother). The method for generating growth-and-obesity profiles of children of grown-up parents cannot be employed for the children of young spouses, as it is based on values of adult height of both parents. In the present scenario, adult height is not available as the parents are still growing. This work modifies the box-interpolation-based model to produce growth-and-obesity profiles of such families. This is accomplished by computing estimated-adult heights of both parents, using the percentiles of their current heights. These values are, then, utilized for the computation of mid-parental (target) heights. This model estimates adult heights and weights of all the family members and expresses as percentages, the degrees to which the individuals are obese (wasted), taking optimal weights as standard. For children, this method, also, provides the information if the incumbents are tall (stunted), based on current-age-mid-parental heights. This procedure is demonstrated through simulated data with an example of a young couple and their twin children. This framework can be adjusted for families, in which, one of the parents is still growing, while the other one has attained adult height. Extreme cases presented earlier have been enhanced and concept of estimated-adult BMI (body-mass index) for children introduced. This index could be used to, roughly, classify a child as obese or wasted. Sociological and psychological implications of underage marriages are, also, looked into.

J29: Growth–and-Obesity Profiles of Children of Karachi using Box-Interpolation Method

This paper introduces quantifiable growth-and-obesity profiles of children in family-centered care. This work presents a model based on the mathematical-statistical technique of ‘box interpolation’, which generates patient- and parent-friendly profiles based on one set of height and weight measurements of parents and children. Mid-parental (Target) heights and optimal weights were compared with measured heights and weights to determine if the children were obese (wasted) and tall (stunted), associating a numerical index with each condition, in the form of percentage. This model, also, estimated adult-heights and weights of children and indicated whether parents were obese (wasted). Data were collected by authors, following standard protocols developed by our team, as part of the NGDS (National Growth and Developmental Standards) Pilot Project. This project was approved by Institutional Review Board. Informed consents were obtained from parents of participating families. Each child was weighed and measured, in the presence of father and mother, barefoot, wearing short underpants, stripped to waist. Data from 70 participants of different localities of Karachi (17 families, consisting of 17 fathers, 17 mothers, 16 boys, 20 girls) were analyzed.  Boys showed a greater risk of obesity (46.15%) as compared to girls (17.65%), when both parents were obese (15 families). Excessive obesity (wasting), failure-to-grow, short children developing normally, and failure-to-thrive, children neither growing nor developing normally, may be the cause of an underlying physical or psychological problem needing a head-to-toe evaluation. The method reported in this paper may be helpful in identifying such cases in children 3-10-year old, if regular height and weight screenings are conducted. Full Text PDF
