Classification of Human Weight Based on Image

Classification of human weight can be determined by body mass index. The body mass index can be calculated by dividing the height by the square of the body weight. According to researchers, this is less practical, so it needs to make a tool that can be used to determine ideal body weight more practically. One way is to use an Android smartphone camera. The camera is used to capture the image of the human body. Then the image is processed by using digital image processing and by using certain algorithms, so it may conclude the person's ideal weight category. The data used in this study are human photos, body weight and height. There are four stages to determine the weight and height based on the image. First, performing an analysis of the calculation of the derived formulas. Second, analyzing the edge detection algorithm. Third, conducting unit convertion, and fourth, proposing several algorithms to calculate the height and weight used to determine the ideal body weight. The results of the evaluation show that Algorithm C (measuring the width of an object starting with the height of the image adjusting half of the height of the object in the image) is the best algorithm with deviation value of 1.85% of the height and 8.87% of the weight, while the system accuracy rate in determining the ideal body weight has reached 78.7%.

Objective: The high prevalence of malnutrition in patients with end-stage of liver disease requires broad intensive measures to evaluate the pre-operative nutritional status while on the waiting list, aiming early disturbance corrections and a better after-transplant prognosis. Methods: An assessment on 33 out of 44 prognosis on liver transplantation waiting list was performed from March, 2004 to January, 2005. The current body weight, dry body weight, ideal body weight, body mass index, the percentage of adequacy of dry body weight / ideal body weight, tricipital skin fold, mid-arm muscular circumference, uncorrected mid-arm muscular area, blood albumin levels, and total lymphocyte count were assessed. Results: Upon the use of the body mass index and percentage of adequacy of the dry body weight / body mass index assessments, higher frequency of eutrofic and obese patients were observed, respectively. The protein depletion was higher than fat depletion in those patients, probably related to the catabolism associated to the liver disease and physical inactivity. Conclusion: Many nutritional measures are necessary in order to improve the accuracy of the results.

SUMMARYIntroduction: Formulas of ideal body weight (IBW) including the body mass index (BMI) of 22 kg/m2 are used under the assumption to provide a healthy weight. Objective: We compare the perceived ideal body weight (PIBW) with the calculated IBW by formulas and the BMI of 22. Methods: We recruited 705 women (20-25 y). Six common formulas and 2 published equations by our team were used. Results: Group regression analysis determined that including the frame size improves the agreement of formulas of Robinson et al, Hammond and Hamwi with the PIBW (p>0.05). Individually, the concordance analysis (higher % of differences <2 kg: PIBW - IBW by formula), determined that for a measured BMI <20, only the Faspyn 1 formula needs to be adjusted by frame size; while Robinson et al, Hammond, Tokunaga (BMI of 22), Faspyn 2 (BMI of 22) and Broca, are equivalent with the PIBW in different intervals of BMI. Conclusions: According to the BMI perceived as overweight (23.8 kg/m2) and perceived as ideal (21.1 kg/m2), caution is suggested when using the IBW formulas for BMI of 22 as a diagnosis. The IBW formulas and BMI of 22 does not necessarily represent a desirable or aesthetic weight. Comparación del peso percibido como ideal con fórmulas de peso ideal y el IMC de 22 kg/m2 en mujeres jóvenes.RESUMEN Introducción: El peso ideal calculado con fórmulas (PIF) y con el índice de masa corporal (IMC) de 22 kg/m2 se emplea bajo el supuesto de proporcionar un peso saludable o estético. Objetivo: Comparar el peso percibido como ideal (PPI) contra el PIF y del IMC de 22. Métodos: Se reclutaron 705 mujeres (20-25 años). Empleamos seis fórmulas comunes y 2 publicadas previamente. Resultados: El análisis de regresión grupal determinó que incluir la complexión corporal mejora la concordancia de las fórmulas de Robinson et al, Hammond y Hamwi con el PPI (p>0.05). Individualmente, el análisis de concordancia (porcentaje mayor de diferencias <2 kg: PPI-PIF), determinó que para un IMC <20 kg/m2 solo la fórmula de Faspyn 1 debe ajustarse por la complexión corporal, mientras que las fórmulas de Robinson et al, Hammond, Tokunaga (IMC de 22), Faspyn 2 (IMC de 22) y Broca, son equivalentes con el PPI en diferentes intervalos de IMC. Conclusiones: de acuerdo con el IMC percibido como sobrepeso (23.8 kg/m2) y percibido como ideal (21.1 kg/m2), las fórmulas de peso ideal y el IMC de 22 deben ser usados con precaución en el diagnóstico de peso ideal ya que no necesariamente representan un peso deseable o estético.

ABSTRACT : RELATIONSHIP BETWEEN THE BODY MASS INDEX (BMI) KNOWLEDGE LEVEL AND THE EFFORT TO MAINTAIN THE IDEAL BODY WEIGHT IN YOUTH AT SMK BINA INSAN CENDEKIA TANGERANG (BICTA) IN 2020Background: The data of Riskesdas in the year of 2018 indicated that there was 8,7% of the youth aged 13-15 years old, and 8,1% of the youth aged 16-18 years old are thin and very thin. Therefore, 16,0% of the youth aged 13-15 years old have an excessive prevalence of body weight and obesity (Kemenkes, 2020).Purpose: To find out the relationship between the knowledge of Body Mass Index (BMI) with the effort to maintain the ideal body weight of the youth.Method: This research conducted using a descriptive correlation design, then the sampling technique was the proportionate stratified random sampling. The research samples were 104 respondents using the analysis of univariate and bivariate, and Wilcoxon test.Results: Based on the Chi-Square test (P-value 0,002 < 0,05). Wilcoxon test obtained in (0,000 < 0,05). There is a meaningful relationship between the variable of knowledge-level and the effort to maintain the ideal body weight.Conclusion and Suggestion: Most of the respondents have a good level of knowledge of the BNI and provide an effort to maintain body weight. Providing the information aims to build better knowledge, so the effort of maintaining body weight can be done appropriately.Keywords: Knowledge, Body Mass Index (BMI), The effort, Youth.

The Ideal

This study aimed to investigate body mass index (BMI) of 102 subjects to be Indonesian military officer candidates. To test the ideal body weight (IBW) used 2 methods for comparison, first from the calculation of IBW by Brodsky’s and modified Broca's formula and ideal BMI from WPRO criteria and second from IBW of the Indian Navy and TNI/POLRI recruitment. A digital integrated instrument for measuring BMI was manufactured where BW and body height (BH) are measured using loadcell and ultrasonic sensor respectively and the result is processed by Arduino Mega 2560 microcontroller. From the separate measurement results there are BW error 0.96%, BH error 3.22%, and BMI error 2.88% compared to using digitally integrated measurement.
