A simplified HDR image processing pipeline for digital photography
High Dynamic Range (HDR) imaging has revolutionized the digital imaging. It allows capture, storage, manipulation, and display of full dynamic range of the captured scene. As a result, it has spawned whole new possibilities for digital photography, from photorealistic to hyper-real. With all these …

Exploring the visualisation of the cervicothoracic junction in lateral spine radiography using high dynamic range techniques
… difficult to visualise in a lateral X-ray image due to the rapid change in the bodys anatomy at the level of the junction, where the shoulders cause a large increase in attenuation. To explore methods of enhancing the appearance of this important area, lateral radiographs of a shoulder …

Advanced Imaging Through FOV and Aperture Manipulation
The fourth system is an HDR imaging device which uses a pair of mirrors to capture multiple copies of the same scene with different exposures. An HDR image is constructed by fusing all the copies together. Compared with other existing techniques, the advantages of the proposed method are: (1) the …

High dynamic range video merging, tone mapping, and real-time implementation
Although High Dynamic Range (High Dynamic Range (HDR)) imaging has been the subject of significant research over the past fifteen years, the goal of cinemaquality HDR video has not yet been achieved. This work references an optical method patented by Contrast Optical which is used to capture …

Architectures for computational photography
… photography refers to a wide range of image capture and processing techniques that extend the capabilities of digital photography and allow users to take photographs that could not have been taken by a traditional camera. Since its inception less than a decade ago, the field today …

Image-based Material Editing
Photo editing software allows digital images to be blurred, warped or re-colored at the touch of a button. However, it is not currently possible to change the material appearance of an object except by painstakingly painting over the appropriate pixels. Here we present a set of methods for …

Neural network based learnings in support of two application domains
… applications in two fields: high dynamic range (HDR) imaging and entrepreneurial prediction. In HDR imaging, multi-exposure fusion (MEF) is the easiest way to produce an HDR image without expensive professional cameras. Employing AI in MEF highly enhances the quality of generated HDR images …

A robust patch-based synthesis framework for combining inconsistent images
Current methods for combining different images produce visible artifacts when the sources have very different textures and structures, come from far view points, or capture dynamic scenes with motions. In this thesis, we propose a patch-based synthesis algorithm to plausibly combine different …

Improving Photometric Camera Accuracy and Image Quality in High Dynamic Range Imaging
… However, the emergence of high dynamic range (HDR) displays, such as OLED and dual-modulation LCD-LED, has enabled more accurate reproduction of a wider range of light intensities. To fully leverage the capabilities of these HDR displays, it is essential to capture images that faithfully …

Development of High Speed High Dynamic Range Videography
… an adaptation of the current high dynamic range image formation methodologies. Due to the high cost of a high speed camera, a minimum number of cameras are desired to form a high dynamic range high speed video system. With a reduced number of cameras spanning a significant range, the errors on …
