There too, the accounts of feminist film culture produced in the mid-to-late 70s tended to emphasize a dichotomy between two concerns of the women's movement and two types of film work that seemed to be at odds with each other: one called for immediate documentation for purposes of political activism, consciousness- raising, self-expression or the search for "positive images" of woman; the other insisted on rigorous, formal work on the medium - or bet-. | Studying Aesthetics in Photographic Images Using a Computational Approach Ritendra Datta Dhiraj Joshi Jia Li James Z. Wang The Pennsylvania State University University Park PA 16802 USA Abstract. Aesthetics in the world of art and photography refers to the principles of the nature and appreciation of beauty. Judging beauty and other aesthetic qualities of photographs is a highly subjective task. Hence there is no unanimously agreed standard for measuring aesthetic value. In spite of the lack of firm rules certain features in photographic images are believed by many to please humans more than certain others. In this paper we treat the challenge of automatically inferring aesthetic quality of pictures using their visual content as a machine learning problem with a peer-rated online photo sharing Website as data source. We extract certain visual features based on the intuition that they can discriminate between aesthetically pleasing and displeasing images. Automated classifiers are built using support vector machines and classification trees. Linear regression on polynomial terms of the features is also applied to infer numerical aesthetics ratings. The work attempts to explore the relationship between emotions which pictures arouse in people and their low-level content. Potential applications include content-based image retrieval and digital photography. 1 Introduction Photography is defined as the art or practice of taking and processing photographs. Aesthetics in photography is how people usually characterize beauty in this form of art. There are various ways in which aesthetics is defined by different people.
