Joint autofocus and registration for video-SAR by using sub-aperture point cloud
International Journal of Applied Earth Observations and Geoinformation, 2023 Due to the existence of antenna phase center (APC) error, drift occurs on the sequence of images acquired by video-SAR back projection (BP) algorithm with respect to a fixed coordinate system. Theoretical analysis shows that the drift is directly related

Leida xuebao, 2013 Dynamic features are important aspects of the ocean. However the dynamic information is lost in most conventional Synthetic Aperture Radar (SAR) image processing methods, because they treat the image as an instantaneous state of the observed area.

Effects of Microlens Array Lens Size on Sub-Aperture Images in Light Field  Cameras
International Journal of Automation and Smart Technology, 2013 The effects of microlens aperture size on 3D imaging quality for a 5 x 5 microlens array in a light field camera are studied by Fourier optics in consideration of pupil sizes and the locations of main lens and each lens in a microlens array. The larger size of the lenses in the microlens array provides higher sub-aperture image resolution.

Parameter Optimization of Multi-Element Synthetic Aperture Imaging Systems [PDF]
Bioautomation, 2007 In conventional ultrasound imaging systems with phased arrays, the further improvement of lateral resolution requires enlarging of the number of array elements that in turn increases both, the complexity and the cost, of imaging systems.

Sub-Aperture Feature Adaptation in Single Image Super-Resolution Model for Light Field Imaging
2022 IEEE International Conference on Image Processing (ICIP), 2022 With the availability of commercial Light Field (LF) cameras, LF imaging has emerged as an up and coming technology in computational photography. However, the spatial resolution is significantly constrained in commercial microlens based LF cameras because of the inherent multiplexing of spatial and angular information.

A Deep Learning Based Spatial Super-Resolution Approach for Light Field Content
IEEE Access, 2021 One of the main issues encountered when working with Light Field technology is the trade-off between spatial and angular resolution. Various approaches have been presented to super-resolve light field in the spatial dimension.
