Relative Anatomical Location for Statistical Non-Parametric Brain Tissue Classification in MR Images

We propose a statistical non-parametric classification of brain tissues from an MR image based on the voxel intensities and on the relative anatomical location of the different tissues. Classically, the overlap of the tissue probability distribution functions for voxel intensities can be reduced by using multi-component (T1w,T2w,Pd,...) MR images, but at a much higher cost for image acquisition. Instead, we generate an artificial image component as the distance from the edges of the segmented brain. The non-parametric k-Nearest Neighbors rule (k-NN) is used since it requires no a priori on the probability distribution of this distance component. The k-NN rule is also tested using different metrics (Euclidean, weighted Euclidean, Mahalanobis) in the classification space to define what "nearest neighbors" are

In a Different Light : Visual Culture, Sexual Identity, Queer Practice

This catalogue represents a series of nine exhibitions on the theme of homosexuality in the arts. With the participation of 112 mainly American artists, there are also seven texts documenting specific exhibitions presented between 1978 and 1991, as well as excepts from 19 historical works. In his introduction, Rinder sets the very broad parameter for the exhibition, while the works have elements of importance to the question of homosexuality and its relation to art, the artists themselves need not be gay or lesbian. Blake elaborates on his choice of curatorial principles: intergenerational slices, mixed artists, queer and straight, oriented towards the public, and representative of the artists themselves. Brief biographical notes on the three editors/curators. 3 bibl. ref

Art and Feminism

Authoritative publication focusing on the role of theory in the evolution of feminist art. Phelan's essay surveying American and British feminist art produced between 1960-2000 traces the "shifting geographies of feminism" by situating diverse formal strategies used by feminist artists within the contexts of abstract expressionim, minimalism, conceptual art, performance art and photographic performance. Her analysis of the ideological forces within representational systems is informed by postructuralism and psychoanalytic theories of sexual difference. Issues of identity, race, sexuality, class, gender and age are considered in relation to the marginalization of women, the objectification of the female body, and essentialism. Includes documentation of numerous artworks and texts by artists and authors working in disciplines of feminist philosophy, psychoanalysis, art history, film theory and literary criticism. Biographical notes. Index of names. Bibliography. Circa 675 bibl. ref
