Motivation

The objective was to develop a more efficient and accurate solution for calorie counting by using deep learning and computer vision. Unlike current calorie tracking applications that rely on manual data entry, Azati aimed to automate the process of estimating calorie content through the analysis of food images.

Main Challenges

One of the key challenges was ensuring a sufficient amount of high-quality training data. Different products and cooking methods resulted in varied calorie counts, and Azati had to collect diverse images of dishes to account for all possible variations. For example, the calorie content of a boiled egg differs from a fried one, and this needed to be captured in the data.

The AI algorithm struggled with inconsistencies in lighting, angles, and dish sizes. To overcome this, Azati had to account for situations like partial food images or varying plate sizes. Manual adjustments were made to compare and calculate data accurately, ensuring that the algorithm could recognize and estimate calorie content correctly.

Our Approach

Market Research

Azati began by analyzing existing software in the market to understand basic operational principles and identify areas for improvement. This step ensured the team could build on existing technologies and enhance the user experience.

Algorithm Development

After studying the necessary documentation and tools, Azati’s team developed a custom algorithm to process food images and estimate calorie content. The algorithm was designed to handle complex dishes and multiple ingredients.

Data Collection and Preparation

Azati collected and prepared high-quality images of dishes for training the AI model. The process involved gathering images from open sources and creating new ones manually to ensure a wide variety of food types and cooking methods were represented.

Machine Learning Training

Once the images were prepared, Azati trained the machine learning model to automatically recognize and categorize food components. The team manually mapped categories, ensuring the AI could distinguish between different parts of a dish, such as garnish and meat.

Template Creation

For each group of food components, Azati created templates that helped the system process the images with maximum accuracy. These templates were used to analyze all images within their respective categories, ensuring consistent results.

Iterative Refinement

The system underwent multiple rounds of processing to refine the data. Each round improved the accuracy of the calorie estimations, resulting in a highly functional prototype.
