The 2017 Predicting Media Interestingness Task
Register to participate in this challenge on the MediaEval 2017 registration site.

The task requires participants to automatically select images and/or video segments which are considered to be the most interesting for a common viewer. Interestingness of media is to be judged based on visual appearance, audio information and text accompanying the data, including movie metadata.

The Predicting Media Interestingness Task was proposed for the first time last year. This year's edition is a follow-up which builds incrementally upon the previous experience. It is not necessary to have participated in last year's task in order to succeed at this year's task.

Participating systems are expected to select frames/video excerpts that are interesting in the context of helping a user to make his/her decision about whether he/she is interested in watching a movie. This use scenario is similar to the one in 2016 and it derives from a use case at Technicolor which involves helping professionals to illustrate a Video on Demand (VOD) web site by selecting some interesting frames and/or video excerpts for the movies.

Two subtasks will be offered to participants:

1) Predicting Image Interestingness

Given a set of key-frames extracted from a certain movie, the task involves automatically identifying those images that viewers report to be interesting. To solve the task, participants can make use of visual content as well as accompanying metadata, e.g., Internet data about the movie, social media information, etc.

2) Predicting Video Interestingness

Given a set of video segments extracted from a certain movie, the task involves automatically identifying the segments that viewers report to be interesting. To solve the task, participants can make use of visual and audio data as well as accompanying metadata, e.g., subtitles, Internet data about the movie, etc.
    Target group
    Researchers will find this task interesting if they work in the areas of human perception and scene understanding. Examples include image/video interestingness/memorability/attractiveness prediction, image aesthetics, event detection, multimedia affect or perceptual analysis, multimedia content analysis, machine learning (though not limited to).

    Data
    The data will be extracted from Hollywood-like movies shared under Creative Commons licenses that allow redistribution.

    For the video interestingness subtask, the data will consist of movie segments (obtained after manual segmentation). Prediction will be carried out on a per movie basis. For the image interestingness subtask, the data will consist of collections of key-frames extracted from the video segments used for the previous subtask (e.g., one key-frame per segment). This will allow comparing results from both subtasks. Prediction will be carried out also on a per movie basis.

    Precomputed features will be provided along with the dataset to help teams from different communities to participate to the task.

    Ground truth and evaluation
    All data will be manually annotated in terms of interestingness by human assessors.

    This year again, a pair-wise comparison protocol will be used. Annotators will be provided with a pair of images/video segments at a time and asked to tag which of the content is more interesting for them. The process will be repeated by scanning the whole dataset. To avoid an exhaustive, full comparison, between all the possible pairs, a boosting selection method will be employed (i.e., the adaptive square design method). The obtained annotations will finally be aggregated to result in the final interestingness degrees of the images/video shots.

    The official evaluation metric will be the mean average precision at 10 (MAP@10) computed over all videos (whereas average precision is to be computed on a per video basis, over the top 10 best ranked images/video segments). MAP@10 is selected because it reflects the VOD use case, where the goal is to select a small set of the most interesting images or video segments.
