This two-volume set of LNCS 12509 and 12510 constitutes the refereed proceedings of the 15th International Symposium on Visual Computing, ISVC 2020, which was supposed to be held in San Diego, CA, USA in October 2020, took place virtually instead due to the COVID-19 pandemic. The 114 full and 4 short papers presented in these volumes were carefully reviewed and selected from 175 submissions. The papers are organized into the following topical sections: Part I: deep learning; segmentation; visualization; video analysis and event recognition; ST: computational bioimaging; applications; biometrics; motion and tracking; computer graphics; virtual reality; and ST: computer vision advances in geo-spatial applications and remote sensing Part II: object recognition/detection/categorization; 3D reconstruction; medical image analysis; vision for robotics; statistical pattern recognition; posters

Among communities in the Mara region of Tanzania, it is considered men's responsibility to maintain "history." But when Jan Bender Shetler's questions turned to specific familial connections within the village, she discovered her male informants had to occasionally leave the room-to ask their wives for clarification. The result is an original and wide-ranging investigation of the gendered nature of historical memory and its influence on the development of the region over the past 150 years. Shetler's exploration of these oral traditions and histories opens exciting new vistas for understanding how women and men in this culture tell their stories and assert their roles as public intellectuals-with important implications for research in African and gender studies, and the history of ethnicity and nationalism.

Do African men and women think about and act out their ethnicity in different ways? Most studies of ethnicity in Africa consider men's experiences, but rarely have scholars examined whether women have the same idea of what it means to be, for example, Igbo or Tswana or Kikuyu. Or, studies have invoked the adage "women have no tribe" to indicate a woman's loss of ethnicity as she marries into her husband's community. This volume engages directly the issue of women's ethnicity and makes stimulating contributions to debates about how and why women's movements have a unifying role in African political organization and peace movements. Drawing on extensive field research in many different regions of Africa, the contributors demonstrate in their essays that women do make choices about the forms of ethnicity they embrace, creating alternatives to male-centered definitions-in some cases rejecting a specific ethnic identity in favor of an interethnic alliance, in others reinterpreting the meaning of ethnicity within gendered domains, and in others performing ethnic power in gendered ways. Their analysis helps explain why African women may be more likely to champion interethnic political movements while men often promote an ethnicity based on martial masculinity. Bringing together anthropologists, historians, linguists, and political scientists, Gendering Ethnicity in African Women's Lives offers a diverse and timely look at a neglected but important topic.

Long before the creation of the Serengeti National Park in Tanzania, the people of the western Serengeti had established settlements and interacted with the environment in ways that created a landscape we now misconstrue as natural. Western Serengeti peoples imagine the environment not as a pristine wilderness, but as a differentiated social landscape that embodies their history and identity. Conservationist literature has ignored these now-displaced peoples and relegated them to the margins of modern society. Their oral traditions, however, provide the means for seeing the landscape from a new perspective.
"Imagining Serengeti "allows us to see the Serengeti landscape as a book of memory that preserves the ways in which western Serengeti peoples have actively transformed their environment and their societies. Moreover, it strengthens the case for involving local communities in conservation efforts that will preserve African environments for the future. Using a new methodology to analyze precolonial oral traditions, Jan Shetler identifies core spatial images, which are then recontextualized into historical time periods through the use of archaeological, linguistic, ethnographic, ecological, and archival evidence. I"magining Serengeti" reconstructs a socioenvironmental history of landscape memory of the western Serengeti spanning the last eighteen hundred years.
