2023 Special Sessions
Computational Imaging using Fourier Ptychography and Phase Retrieval
Session Organizing Chairs:
Andre Van Rynbach, AFRL (United States)
Tony Allen, Purdue University (United States)
Access to the full complex phase and amplitude of a light wave in an imaging system can greatly enhance reconstructed images in applications such as microscopy, astronomy, remote sensing, and ptychography. However, direct measurement of the optical field is not possible with existing electronic measurement devices, which record only the magnitude of the irradiance. Computationally based phase retrieval methods attempt to overcome this limitation by recovering the optical phase from multiple irradiance measurements together with prior information, which can be enhanced using powerful machine learning techniques. This special session highlights recent developments in Fourier ptychography and phase retrieval methods along with exciting implications for further advances in computational imaging.
Processing at the Edge
This session is jointly sponsored by the Computational Imaging XXI and the Imaging Sensors and Systems 2023 conferences.
Session Organizing Chairs:
Boyd Fowler, Omnivision Technologies, Inc. (United States)
Stanley Chan, Purdue University (United States)
Modern image sensors are increasingly capable of performing difficult vision tasks, for mobile, automotive, security and medical applications. However, increasing demands for low power, high-bandwidth, and high complexity are forcing computation to be pushed nearer to the sensor or “edge” of the sensing system. This special session invites speakers to discuss emerging methods for moving processing to the edge. Topics include, but are not limited to, on-chip sensor processing, low-power edge processors, algorithms for edge processing, stacked image sensors with integrated processing, low power image sensors, and imaging applications that utilize edge processing. The International Image Sensors Society (IISS) is co-sponsoring this session.
Imaging with Coded Apertures
Session Organizing Chairs:
Doga Gursoy, Argonne National Laboratory (United States)
Beginning with the advent of coded-aperture space telescopes as an efficient imaging technique back in the early 1960s, coded-aperture imaging has grown today into a well-established technique in many fields of study from imaging of microscopic materials to astronomical objects. While conventionally used as amplitude-only modulators of the incident light, coded-apertures are increasingly used for different types of light modulation and data acquisition schemes such as for imaging with coherent light or for scanning-based systems. This session will focus on the recent trends in the uses of coded-apertures for existing and emerging applications and will cover topics ranging from development and optimization of coded-apertures to image reconstruction algorithms and data acquisition schemes.
Neutron Imaging Beyond Traditional Radiography
Session Organizing Chairs:
Sven Vogel, Los Alamos National Laboratory (United States)
Alexander Long, Los Alamos National Laboratory (United States)
Recent advances have pushed the field of neutron imaging beyond traditional attenuation-based radiography techniques and enabled approaches such as phase contrast imaging, grating interferometry, absorption resonance imaging, and Bragg-edge imaging. As improvements in detector technology drive the limits of neutron imaging capabilities, new and innovative experimental setups, along with state-of-the-art analysis techniques, are required to meet the unique demands within these novel applications. This special session aims to bring together researchers at the frontier of the neutron imaging community to discuss the latest achievements and open challenges in neutron imaging applications and techniques.
