CFP: Special Edition of Pattern Recognition Letters: Celebrating the life and work of Maria Petrou Maria Petrou was an outstanding scientist with a well developed sense of humour, and seemingly tireless energy. The aim of this special edition of Pattern Recognition Letters is to celebrate Maria's life and work. The aim is to collect together both scientific articles and personal reflections which illuminate her contributions to our field. We encourage contributions from both those who worked with Maria, and those whose work was influenced by her. Maria's interests were broad, spanning image processing and analysis, remote sensing, medical image analysis, computer vision and, of course, pattern recognition. She was noted for her key contributions the trace transform, mixed pixel classification (remote sensing community), Hough, contextual classification (multi resolution MRF), and edge/line detection. See http://www.journals.elsevier.com/pattern-recognition-letters/call-for-papers/celebrating-the-life-and-work-of-maria-petrou/ We invite three different types of contribution: a) Short recollections of Maria and reflections on her life and work, that capture her personality and interests. We are particularly keen to receive photographs to illustrate these accounts. We would hope to edit both the photographs and accounts together into a montage capturing the different facets of her life and work. b) Reviews that place her work in the context of the literature in the field, focus on her scientific contributions and assess their lasting influence. c) Original scientific papers in the broad areas of Maria's research interests, pointing out their relevance to her work. These could be posthumous papers with Maria as co-author, submitted by one of her collaborators or students. Although we want the special edition to reflect Maria's life and personal qualities, we expect that the bulk of papers in the Special Edition will be original scientific articles focused around her research interests.
