NutriSnap Scientific & Volumetric Framework
Traditional dietary logging relies on self-reported estimates, barcode lookups, and manual kitchen scales. Peer-reviewed epidemiological studies demonstrate that self-reported calorie intake is underreported by an average of 28% to 47%, primarily due to portion distortion, hidden cooking fats, and friction-induced estimation fatigue. NutriSnap was built to replace estimation with high-resolution computer vision and physical food geometry.
1. 3D Volumetric Mesh Reconstruction
Using monocular depth cues, edge segmentation, and contextual reference dimensions, our vision models reconstruct a 3D point cloud of food items on your plate to calculate accurate volume in cubic centimeters ($cm^3$).
2. Empirical Density Matrix ($g/cm^3$)
Volume is mapped against our proprietary library of food density coefficients derived from USDA FoodData Central and empirical food science testing, converting estimated volume to mass (grams) with 94%+ lab precision.
3. Multi-Component Food Segmentation
Mixed dishes such as stir-fries, grain bowls, and casseroles are segmented into discrete nutritional layers, accounting for cooking oils, starch absorption, and volumetric shrinkage during heat processing.
