This is a normal food detection app which gives you the idea about meeting your calorie goals against the meal you are having

Dr Foodie (Object detection using deep learning with OpenCV and Python)

OpenCV dnn module supports running inference on pre-trained deep learning models from popular frameworks like Caffe, Torch and TensorFlow.

YOLO (You Only Look Once)

Download the pre-trained YOLO v3 weights file from this link and place it in the current directory or you can directly download to the current directory in terminal using Provided all the files are in the current directory, below command will apply object detection on the input image fruits.jpg.

$ python yolo_opencv.py --image fruits.jpg --config yolov3.cfg --weights yolov3.weights --classes yolov3.txt

Command format

python yolo_opencv.py --image /path/to/input/image --config /path/to/config/file --weights /path/to/weights/file --classes /path/to/classes/file_

As of now this prototype can detect any of the food items among popular fruits(orange, apple, banana), vegetables (carrot, broccoli), fast food(pizza, sandwich) and sweets(cake, donut). With further development this can be upscaled to detect thousands of different kinds of food. Further this displays the result about user's calorie guidance too.
