Important Dates

LSC'22 uses a new larger dataset which is currently under preparation. As with previous instances of the LSC competition, the multimodal dataset was generated by one active lifelogger and will be 18 months in length. The dataset consists of two password protected files:
  • Core Image Dataset of wearable camera images, fully redacted and anonymised in 1024 x 768 resolution, captured using a Narrative Clip device. These images were collected between Jan 2019 - Jun 2020. All faces and readable text have been removed, as well as certain scenes and activities manually filtered out to respect local privacy requirements.
  • Metadata for the collection, consisting of textual metadata representing time and locations, visual concepts, OCR text, etc…
  • For access to the full dataset, please email cathal dot gurrin at dcu.ie

LSC'22 Data Release Forms

Participants are required to sign two forms to access the datasets, an organisational agreement form for your organisation (signed by the research team leader) and an individual agreement form for each member of the research team that will access the data. The organisation agreement form should be sent to the LSC organisers (lsc@computing.dcu.ie) in PDF format. The individual agreement form must be signed by all researchers who will use the data and kept by the organisation on file. It should not be sent to the organisers, unless requested at a later date.

  1. Organisation Agreement form: to be signed by the organisation to which the participants belong. This form must be signed and sent by email to LSC organisers (lsc@computing.dcu.ie).
  2. Individual Agreement form: to be signed by each individual researcher wishing to use the LSC data collection. This form must be filed by the participating organisation, but it does not need to be sent to the organisers.

Upon completion of this process, the participants will be sent details about how to access the dataset. Please note that the zip file is also password protected.

A suitable reference for the dataset in LSC and subsequent papers is as follows:

LSC'22 Development Topics


  • The suite of development topics will be available to assist teams in developing their lifelog search engines. The LSC'19 topics are available for system testing as well as the LSC'20 topics with relevance judgements and the LSC'21 topics with relevance judgements. These have been developed for the 2016 subset of the dataset and the relevance judgments are provided only from the 2016 data.
  • Associated with these development topics, there will be an evaluation system that allows teams to input image IDs and receive a score depending on submission accuracy, which will be operational soon.
