About Us
Welthungerhilfe (WHH) is an international aid agency headquartered in Germany with its vision for “Zero Hunger by 2030”, the second sustainable development goal set by the UN. It has thousands of programs fighting hunger in more than 30 countries. (https://www.welthungerhilfe.org/">https://www.welthungerhilfe.org) (https://www.childgrowthmonitor.org/">https://www.childgrowthmonitor.org).
Child Growth Monitor (CGM) is Welthungerhilfe’s digital innovation project leveraging AI to fight child malnutrition. Around 200 million children around the world are suffering from malnutrition. Malnutrition contributes to one-third of deaths of children under the age of five. In the fight against malnutrition, detection is the first important step, but this is not an easy task: Measuring children with traditional methods is still a complex, slow, and expensive task, frequently resulting in poor data and wrong assessments of the child’s health. Early detection of malnutrition becomes the key to initiating treatment, minimizing the risk of complications,
and saving lives by reducing the chances of death to a great extent.
Our solution to measure children replaces hardware (bulky measuring boards and physical scales) with off-the-shelf cell phones and AI. CGM uses augmented reality-enabled smartphones to record 3D scans of children. Artificial Intelligence is used to predict their height, weight, and middle upper-arm circumference needed to know the nutritional status of the children.
