How does a house remember? heritage-ising return migration in an Indonesian-Chinese house museum in Guangdong, PRC

This paper is an attempt to integrate heritage and museum studies through exploring the complex relationship between the materiality of architecture and social memories with a house museum of return migration in Guangdong, PRC as a case study. It unveils that the ongoing process of memory is intrinsically intertwined with spatial and temporal dimensions of the physical dwelling and built environment and the wider social-historical context and power relations shaping them. I argue that it is the house as ‘object of exhibit’ just as much as the exhibits inside the house that materialises the turbulent and traumatic migratory experience of Returned Overseas Chinese, embodies their memories and exposes the contested nature of museumification. By looking at the socially and geographically marginalised dwelling of return migrants, the house draws people’s attention to the often neglected importance of conceptual periphery in re-theorising what is often assumed to be the core of heritage value. It points to the necessity to integrate displaced, diasporic, transnational subjects to heritage and museum studies that have been traditionally framed within national and territorial boundaries.

Reduced-Reference Image Quality Assessment Based on Edge Preservation

Assessing the subjective quality of processed images through an objective quality metric is a key issue in multimedia processing and transmission. In some scenarios, it is also important to evaluate the quality of the received images with minimal reference to the transmitted ones. For instance, for closed-loop optimisation of image and video transmission, the quality measure can be evaluated at the receiver and provided as feedback information to the system controller. The original images - prior to compression and transmission - are not usually available at the receiver side, and it is important to rely at the receiver side on an objective quality metric that does not need reference or needs minimal reference to the original images. The observation that the human eye is very sensitive to edge and contour information of an image underpins the proposal of our reduced reference (RR) quality metric, which compares edge information between the distorted and the original image. Results highlight that the metric correlates well with subjective observations, also in comparison with commonly used full-reference metrics and with a state-of-the-art reduced reference metric. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
