“…Furthermore, participants' opinions regarding repeated images for the same event were varied -some participants deliberately selected multiple images for an event in order to capture different aspects, whilst others commented that videos with multiple photographs of the same events "contained too many useless images". Knowing when and how to cluster multiple images for an event is a challenge to be addressed in future work, but existing literature about behaviour with other digital photography collections indicates that aspects such as time, location and appearance of images may be important [11]. Based on these observations, we therefore suggest that REQ 5 -video summaries should go beyond simply providing timelapse representations of events, and should only include multiple images for an event where these images provide additional details not represented well by a single image.…”

Reviewing lifelogging data has been proposed as a useful tool to support human memory. However, the sheer volume of data (particularly images) that can be captured by modern lifelogging systems makes the selection and presentation of material for review a challenging task. We present the results of a five-week user study involving 16 participants and over 69,000 images that explores both individual requirements for video summaries and the differences in cognitive load, user experience, memory experience, and recall experience between review using video summarisations and non-summary review techniques. Our results can be used to inform the design of future lifelogging data summarisation systems for memory augmentation.

“…The topic that is most often used is related to people [29], [26], [30]. Next, there is a tendency for photos concerning places [31], [32], [33], [28], [34], [35], [2] or related to various time periods [5], [29], [28], [36], [37]. Also, it seems that many people prefer to organize their collection based on a specific event or circumstance, such as a wedding, a baptism, a congress, a meeting at the workplace, etc.…”

Purpose- The number and the variety of photos have grown to a great extent as they can be created anytime, everywhere and spontaneously. Searching for a particular photo file has become a boring, repetitive and tedious activity. The application of an ontology to express the user profile characteristics relation with the narrative, spatial, time and other types of information of the collected photos becomes imperative.Design/methodology/approach -The work presented in our article includes the development of a personal photograph collections ontology (MyOntoPhotos) specialising in documenting the metadata of the topics that end-users prefer mostly to capture with their devices. An extensive survey, among 650 participants, was conducted with the use of an online questionnaire comprised of semi-closed questions, following the Likert scale and the scale category grading.Findings -The ontology created was based on the results of an extensive survey aiming to identify thematic areas of interest, apart from spatial and temporal information, as other similar efforts did in the past. It is mentionable that the survey results proved the majority of the responders selected 22 thematic tags.Originality/value - Based on the research findings an innovative concept for a mobile application is presented, focusing on enhancing end-users photo collections organizing and retrieval functions.

“…Combinations of the two previous criteria are of course proposed in numerous works [8,14,11,15,16]. Naaman et al [14] propose to hierarchically organize an image collection, while [11] provides a one level partition.…”

Life Gallery: event detection in a personal media collection

Usage of camera-equipped mobile devices raises the need for automatically organizing large personal media collections. Event detection algorithms have been proposed in the literature to tackle this problem but a shortcoming of these studies resides in the lack of comparison of the different solutions. The goal of this work is then to provide a set of tools for the assessment of an event detection method.Our first contribution is our prototype Life Gallery, which aims to retrieve metadata of a personal media collection in order to facilitate the building of a benchmark. Our second contribution is an event detection algorithm based on successive refinements of an initial temporal partition. Our solution uses a simple algorithm that regroups consecutive similar media or split groups with dissimilar media.The choice to provide a basic solution is to compare in a future work our results with more complex solutions, in order to really assess the benefit of these latter. Finally, our third contribution is a benchmark of 6 different users' collections obtained thanks to our Life Gallery application.
