Validating the Detection of Everyday Concepts in Visual Lifelogs
[chapter]
2008
Lecture Notes in Computer Science
Preserved Fulltext
Within this work, we explore the applicability of semantic concept detection, a method often used within video retrieval, on the novel domain of visual lifelogs. ...
By doing so it determines the probability of a concept's presence. We apply detection of 27 everyday semantic concepts on a lifelog collection composed of 257,518 SenseCam images from 5 users. ...
We also would like to extend our thanks to the participants who made their personal lifelog collection available for these experiments, and who partook in the annotation effort. ...

Visual recording of everyday human activities and behaviour over the long term is now feasible and with the widespread use of wearable devices embedded with cameras this offers the potential to gain real ...
The technology of automatic detection of concepts enables searching through visual lifelogs based on semantic attributes and this kind of contentbased search on visual media has been validated as use-ful ...

Using semantic concepts to manage lifelog data relies on the fusion of automatically detected concepts to provide a better understanding of the lifelog data. ...
We argue that in noisy domains such as lifelogging, the management of data needs to include semantic reasoning in order to deduce a set of concepts to represent lifelog content for applications like searching ...
In this paper, we investigate the definition of everyday concepts and their automatic detection from visual lifelogs in order to satisfy the requirements for indexing everyday multimedia lifelogs. ...
