## Recognitions

J. K. Aggarwal's extensive scientific contributions have led to several awards being established in his honor. Chief among these is the biennial IAPR J. K. Aggarwal Prize, presented by the International Association for Pattern Recognition (IAPR). Awarded first in 2006, this prestigious award recognizes a young scientist, under the age of 40, who has made significant and impactful contributions to a field relevant to the IAPR community. Early recipients of the award include Song-Chun Zhu, Antonio Torralba, and Rene Vidal. More recent recipients include Fei Fei Li, Kristen Grauman, and Abhinav Gupta. Recipients of this prize are selected based on nominations and endorsements from IAPR member societies. The award includes the opportunity to present an invited talk at the International Conference on Pattern Recognition (ICPR) and to contribute to a special issue of Pattern Recognition Letters.
Other awards include the J.K. Aggarwal Endowed Undergraduate Presidential Scholarship in Electrical & Computer Engineering awarded by the Cockrell School of Engineering, University of Texas at Austin. The J.K. Aggarwal Endowed Presidential Scholarship was established through an anonymous donor in his honor by an initial contribution of $50,000 and later augmented by additional contributions, now with a total exceeding $250,000, so that as many as five scholarships are given each year.
Another notable recognition in J. K. Aggarwal's honor is the Aggarwal Endowed Presidential Scholarship in Indian Studies for Undergraduates, administered by the South Asia Institute at the University of Texas. Established in 2010 by the Board of Regents of The University of Texas System, this scholarship benefits the College of Liberal Arts and was made possible through the generous contributions of J.K. Aggarwal and Shanti J. Aggarwal. The scholarship awards up to $3,000 to outstanding juniors and seniors at the University of Texas, further extending Dr. Aggarwal's legacy of supporting academic excellence and fostering a deeper understanding of Indian studies.
The J.K. Aggarwal Huddle Room in the Engineering Education and Research Center (EERC) at the University of Texas at Austin serves as yet another tribute to Professor J. K. Aggarwal’s profound influence on the field of computer vision and his dedication to education over a fifty-year career. This space was established through a fundraising initiative led by Dr. Aggarwal's former students, who sought to honor his legacy by creating a place that reflects his commitment to mentorship and research. Contributions from alumni and friends helped raise over $125,000, creating the J.K. Aggarwal Endowed Excellence Fund for graduate students, intended to support future generations in electrical and computer engineering. The room is designed as a collaborative space, encouraging interdisciplinary learning and innovation in engineering, embodying the principles that Dr. Aggarwal championed. This named room not only memorializes his achievements but also serves as an inspiration for students and faculty to continue advancing in fields related to Dr. Aggarwal's pioneering research.
