🗄️ Files Structure

Level I. Primary Categories

The dataset contains three main folders and a stats.json file. The folders keep the visual features extracted from various sources, including full_movies for frame-level visual features extracted from full-length movie videos, movie_shots for the shot-level (i.e., important frames) visual features extracted from full-length movie videos, and movie_trailers for frame-level visual features extracted from movie trailers videos.

Level II. Visual Feature Extractors

Inside each of the mentioned folders, there are two folders titled incp3 and vgg19, referring to the feature extractor used to generate the visual features, which are Inception-v3 (GoogleNet) and VGG-19, respectively.

Level III. Contents (Movies & Trailers)

Inside each feature extractor folder (e.g., full_movies/incp3 or movie_trailers/vgg19) you can find a set of folders with unique title (e.g., 0000000778) indicating the ID of the movie in MovieLenz 25M (link) dataset. Accordingly, you have access to the visual features extracted from the movie 0000000778, using Inception-v3 and VGG-19 extractors, in full-length frame, full-length shot, and trailer levels.

Level IV. Packets

To better organize visual features, each movie folder (e.g., 0000000778) has a set of packets named as packet0001.json to packet000N.json saved as json files. Each packet contains a set of objects with frameId and features attributes, keeping the equivalent frame-ID and visual feature, respectively. In general, every 25 object (frameId-features pair) form a packet, except the last packet that can have less objects.

The described structure is presented below in brief:

> [full_movies]    ## visual features of frame-level full-length movie videos
  > [incp3]        ## visual features extracted using Inception-v3
    > [movie-1]
      > [packet-1]
      > [packet-2]
      ...
      > [packet-m]
    > [movie-2]
    ...
    > [movie-n]
  > [vgg19]        ## visual features extracted using VGG-19
    > [movie-1]
    ...
    > [movie-n]
> [movie_shots]    ## visual features of shot-level full-length movie videos
  > [incp3]
    > ...
  > [vgg19]
    > ...
> [movie_trailers] ## visual features of frame-level movie trailer videos
  > [incp3]
    > ...
  > [vgg19]
    > ...

`stats.json` File

The stats.json file placed in the root contains valuable information about the characteristics of each of the movies, fetched from MovieLenz 25M (link).

[
  {
        "id": "0000000006",
        "title": "Heat",
        "year": 1995,
        "genres": [
            "Action",
            "Crime",
            "Thriller"
        ]
    },
