The goal of this study was to develop an automated monitoring system for the detection of pigs’ bodies, heads and tails. The aim in the first part of the study was to recognize individual pigs (in lying and standing positions) in groups and their body parts (head/ears, and tail) by using machine learning algorithms (feature pyramid network). In the second part of the study, the goal was to improve the detection of tail posture (tail straight and curled) during activity (standing/moving around) by the use of neural network analysis (YOLOv4). Our dataset (n = 583 images, 7579 pig posture) was annotated in Labelbox from 2D video recordings of groups (n = 12–15) of weaned pigs. The model recognized each individual pig’s body with a precision of 96% related to threshold intersection over union (IoU), whilst the precision for tails was 77% and for heads this was 66%, thereby already achieving human-level precision. The precision of pig detection in groups was the highest, while head and tail detection precision were lower. As the first study was relatively time-consuming, in the second part of the study, we performed a YOLOv4 neural network analysis using 30 annotated images of our dataset for detecting straight and curled tails. With this model, we were able to recognize tail postures with a high level of precision (90%)
For German-speaking tourists, an Oriental market (in Arabic: souq) is an exotic place representing the ‘Otherness’. Referring to this Oriental context, the article aims to answer the following questions: What are the tourists’ imaginaries and social narratives and what is the role that cultural brokers play? Gaining insight into the imaginaries and on-site performances of German-speaking tourists of a mega-cruise liner will contribute to the discussion of imaginaries and embodied performances in general as well as the mediation and the construction of space. The research reported upon in the article is part of a larger field study (2012–2014) in Souq Muttrah, the oldest and formerly main market in Oman. Participant observation, photography and in-depth interviews with different types of tourists, local customers, cultural brokers and on-board employees were conducted and marketing material was analysed. Results indicate that in the marketing material, the tourists are already beginning to travel backwards in time. During their visit to the souq, the multi-sensory performances and embodied imaginaries are enhanced by stories of the Arabian Nights. Cultural brokers play an essential role in ‘localizing’ the tourist experience. They adjust their own identities and direct the tourists’ performances at different stages, similar to an Oriental theme park, for example, they stop at a frankincense shop.
'The Post-digital Condition' is the opening essay from the essay collection by INC's Miriam Rasch, Swimming in the Ocean: Texts from a Post-digital World, to be published in Dutch by De Bezige Bij in June 2017. The translation was done by Nadia Palliser, the (analogue) photos come from project Wendepunkt by Maarten van Riel.
