Abstract: Now a day, people across the universe are becoming more sensitive to their diet. Unbalanced diet can cause many problems like weight gain, obesity, sugar, etc. So different systems were developed so as to analyze food images to calculate calorie, nutrition level etc. This paper gives a brief review of these systems and proposes a effective way to measure and manage daily food intake of patients and dietitians. The system will take the images of food and using image processing and segmentation, it calculates the nutrition and calorie content in the food. The proposed system will certainly improve and facilitate the current calorie measurement techniques.
