Especially in elderly people, nutrition is an essential modulator of health and well-being. Nutritional intake in older people is sometimes hampered by a variety of circumstances like isolation depression, weak muscles etc. which increases the risk of various diseases. An effective Food Assessment system that classifies and estimates calorie requirements from a cooked food image is highly recommended, allowing a person to discover what foods contain and how healthy it can be. In this paper a dietary assessment system is developed which classifies the given Indian cooked food image and further estimates its Calories and nutrients by obtaining food region. The proposed method was tested on certain fruits and cooked foods, yielding an average error rate of 8.31, which is highly acceptable. Keywords---CNN, Indian datasets, image processing, calibration object, estimation. Introduction To live a healthy and fit life we need to consume right amount of nutrient which is also an essential modulator of well being in elderly persons (Krishnaswamy, 2011). Due to lack of food knowledge and difficult computations, manually consuming the correct amount of nutrients is a difficult task. Moreover, in elderly persons Isolation depression weak muscle not only hampers’ the nutritional intake but also increases the risk of malnutrition and many diseases (Leena Gautam, 2022). An effective Food Assessment system that defines and estimates nutrient requirements from the given food is highly recommended, allowing
