Sommario/riassunto

A human observer is able to recognize the color of objects irrespective of the light used to illuminate them. This is called color constancy. A digital camera uses a sensor to measure the reflected light, meaning that the measured color at each pixel varies according to the color of the illuminant. Therefore, the resulting colors may not be the same as the colors that were perceived by the observer. Obtaining color constant descriptors from image pixels is not only important for digital photography, but also valuable for computer vision, color-based automatic object recognition, and color imag

Sommario/riassunto

This book provides a timely study of community-based activism in contemporary South Africa. Grounded in oral history, the book examines the acquired expertise and life experiences of an impactful South African activist, Mandla Majola, within the context of the people, circumstances, and affiliations that have shaped his strategic thinking and practice. The authors situate Mandla Majola’s activist and everyday experiences within histories of the complex connections between post-apartheid political and social movements and human rights discourse as they emerged after 1994. The book illuminates the relationship of state power to public health activism for HIV, tuberculosis and COVID-19 and for a life of basic human dignity, including access to sanitation and housing. Mandla Majola’s life spotlights the inspiring, sometimes grueling, and tireless quotidian work of thousands of “invisible” community-based activists whose collective actions have impacted the entire spectrum of social and economic rights of untold numbers of people in South Africa and beyond. Louise Penner is Associate Professor of English at UMass Boston specializing in Victorian Literature and Culture and Global Health Humanities. Her published work as author and editor includes Victorian Medicine and Social Reform: Florence Nightingale among the Novelists (Palgrave, 2010), and Victorian Medicine and Popular Culture (2015). Rajini Srikanth is Dean of Faculty and Professor of English and Human Rights at the University of Massachusetts Boston. He is the author and co-editor of several books, including Interdisciplinary Approaches to Human Rights: History, Politics, Practice (2018) and Climate Justice and Public Health: Realities, Responses, and Reimaginings for a Better Future (2024).
