File Structure

--UECFOOD-100 Segmented/

    -- ann/
        -- ann/  .json    //annotation for images

-- obj_class_to_machine_color.json

In “ann”, annotations are saved as “json”
    - 0.jpg.json
          - 1.jpg.json
          - 2.jpg.json
In “img”, real train and test images are saved as “jpg”
          - 0.jpg
          - 1.jpg
          - 2.jpg
In “masks_human”, real image and mask comparisons are saved as “png”
          - 0.png
          - 1.png
          - 2.png
In “masks_machine”, mask images are saved as “png” (this is what we used)
          - 0.png
          - 1.png
          - 2.png

In “obj_class_to_machine_color.json”, labels and the rgb color distribution is stored. 
          "rice": [1,1,1],
      "fried rice": [2,2,2],
      "teriyaki grilled fish": [3,3,3]
… 
User can select any of the annotation selection for their training process whichever suits them. 
(annotations or machine_masks to extract annotated areas of the images)
