Object Detection in Indian Food Platters using Transfer Learning with YOLOv4
This addresses the problem of recognizing Indian food dishes in images for applications in food analysis or cultural preservation, but it is incremental as it applies an existing method to a new domain.
The paper tackled object detection in Indian food platters by creating a labeled dataset and applying transfer learning with YOLOv4, achieving an overall mAP of 91.8% and an f1-score of 0.90 for a 10-class dataset.
Object detection is a well-known problem in computer vision. Despite this, its usage and pervasiveness in the traditional Indian food dishes has been limited. Particularly, recognizing Indian food dishes present in a single photo is challenging due to three reasons: 1. Lack of annotated Indian food datasets 2. Non-distinct boundaries between the dishes 3. High intra-class variation. We solve these issues by providing a comprehensively labelled Indian food dataset- IndianFood10, which contains 10 food classes that appear frequently in a staple Indian meal and using transfer learning with YOLOv4 object detector model. Our model is able to achieve an overall mAP score of 91.8% and f1-score of 0.90 for our 10 class dataset. We also provide an extension of our 10 class dataset- IndianFood20, which contains 10 more traditional Indian food classes.
