 In the "image" folder, it contains 2 subfolders: "Fractured" and "Non-fractured", and each image is stored in corresponding folder in JPG format.
 In the "Annotations" folder, it contains 4 subfolders: "COCO JSON", "PASCAL VOC", "VGG JSON", and "YOLO". Annotations are stored in their corresponding folders. More details can be read in ### Annotations section.
 In the "utilities" folder, it contains several programming scripts that could be used to convert the raw files to a more readable format. None of them were used in this dataset.
-The "dataset.csv" contains many basic variables for each image: 
-    - image_id [string]: The unique identifier for each radiograph image in the dataset.
-    - hand [int]: A binary indicators (1 or 0) marking the presence of hand in the radiograph
-    - leg [int] : A binary indicators (1 or 0) marking the presence of leg in the radiograph
-    - hip [int] : A binary indicators (1 or 0) marking the presence of hip in the radiograph
-    - shoulder [int]: A binary indicator (1 or 0) marking the shoulder in the radiograph
-    - mixed [int]: A binary indicator of whether the image contains multiple body parts.
-    - hardware [int]: A binary indicator marking the presence of medical hardware (i.e. screws or plates) in the image.
-    - multiscan [int]: A binary indicator signifies whether the image is part of a set of multiple scans.
-    - fractured [int]: A binary indicator of whether there is a fracture present in the image.
-    - fracture_count [int]: The number of fractures present in the image.
-    - frontal [int]: A binary indicator denoting the front orientation of the radiograph
-    - lateral[int]:  A binary indicator denoting the side orientation of the radiograph
-    - oblique [int]: A binary indicator denoting denoting the angled orientation of the radiograph
