Abstract art or the politics and pedagogies of getting read

The writing of academic abstracts is more than a tiresome necessity of scholarly life. It is a practice which goes beyond genre and technique to questions of identity and the promotional economies of academic work. In this paper we deconstruct a series of abstracts from a variety of refereed journals and conferences and develop a set of questions that allow us to 'read' the representation of data, argument, methodology and significance. We argue that the rules of abstract engagement are fluid and increasingly important with the advent of online journals and global citation indices. We suggest that abstract art is now an obligatory aspect of postgraduate supervision.

Kerry Freedman's Teaching visual culture : curriculum, aesthetics and the social life of Art

Teaching Visual Culture: Curriculum, Aesthetics and the Social Life of Art, Kerry Freedman (2003) New York: Teachers College Press & Reston: National Art Education Association, xiv + 187 pp., ISBN 0-8077-4372-0 (hbk £29.95)

This critical review has two principal goals. First of all, it will briefly summarize how Kerry Freedman’s ambitious eight-chapter monograph initially sets in train a number of key themes, all of which are aimed at enlarging if not transforming visual arts practice. Secondly, it will critically disclose a small set of pivotal assumptions which call any uncritical support for visual culture as the panacea for arts education into question. More particularly, we shall conclude, the logical underpinnings of Teaching Visual Culture are open to serious doubt in at least two respects.

Re-photography as critical strategy in recent art

Re-photography describes a set of contemporary art practices which involve the mechanical reproduction and re-presentation of photographic imagery appropriated from a variety of cultural sources. The paper takes as its focus a range of re-photographic activities emanating from New York in the early 1980s in which the author discusses certain issues pivotal to an understanding of the status of contemporary art and its possibilities for critical function.

Efficient and accurate set-based registration of time-separated aerial images

This paper addresses the task of time-separated aerial image registration. The ability to solve this problem accurately and reliably is important for a variety of subsequent image understanding applications. The principal challenge lies in the extent and nature of transient appearance variation that a land area can undergo, such as that caused by the change under illumination conditions, seasonal variations, or the occlusion by non-persistent objects (people, cars). Our work introduces several major novelties (i) unlike previous work on aerial image registration, we approach the problem using a set-based paradigm; (ii) we show how image space local, pair-wise constraints can be used to enforce a globally good registration using a constraints graph structure; (iii) we show how a simple holistic representation derived from raw aerial images can be used as a basic building block of the constraints graph in a manner which achieves both high registration accuracy and speed; (iv) lastly, we introduce a new and, to the best of our knowledge, the only data corpus suitable for the evaluation of set-based aerial image registration algorithms. Using this data set, we demonstrate (i) that the proposed method outperforms the state-of-the-art for pair-wise registration already, achieving greater accuracy and reliability, while at the same time reducing the computational cost of the task and (ii) that the increase in the number of available images in a set consistently reduces the average registration error, with a major difference already for a single additional image.
