Investigations on the potential application of machine vision lenses for depth measurement by exploiting chromatic aberrations

Measurement: Sensors, 2022
Chromatic (spectral) aberrations are image imperfections that are disadvantageous for standard image processing tasks and are typically compensated through the application of different types of glass during lens design.

Image quality and segmentation [PDF]

Medical Imaging 2018: Image-Guided Procedures, Robotic Interventions, and Modeling, 2018
Algorithms for image segmentation (including object recognition and delineation) are influenced by the quality of object appearance in the image and overall image quality. However, the issue of how to perform segmentation evaluation as a function of these quality factors has not been addressed in the literature.

Transformer For Image Quality Assessment [PDF]

2021 IEEE International Conference on Image Processing (ICIP), 2021
Transformer has become the new standard method in natural language processing (NLP), and it also attracts research interests in computer vision area. In this paper we investigate the application of Transformer in Image Quality (TRIQ) assessment. Following the original Transformer encoder employed in Vision Transformer (ViT), we propose an architecture ...
