Hemoglobin (Hb) is an imperative constituent of red blood cells(RBC).Assessment of individual physiological status is accomplished by measuring Hb concentration in human Wood. The limitations associated with invasive methods are distress during sample collection, wide analysis time and disability to provide real time monitoring. These limitations were addressed by a gamut of non- invasive schemes. Hemoglobin extraction and its analysis are challenging tasks in Medical image processing. In this invention, we have a NIR sensor to efficiently detect Hemoglobin in the body. The methods include support vector machine algorithm, to detect the Hemoglobin in body based on the signals from NIR sensor. The only optimal solution to measure the Hemoglobin without blood sample is non- invasive method using Signal analysis
