High Dynamic Range imaging techniques, used in combination with gigapixel imaging technology, allow creation of highlydetailed, evenly-exposed panoramic photographs of a space in 360-degrees. Typically obtaining correct exposure across a 360-degree plane of view is difficult, leading to blown-out highlights and muddled shadows in certain areas of the image. High Dynamic Range imaging techniques...

This paper offers an overview of the challenges and opportunities presented by high dynamic range (HDR) imaging. We examine the length of the imaging pipeline, from creation and storage through image editing and viewing, and discuss how each stage is affected by a move to HDR.

This article describes the theory and application of high dynamic range imaging (HDRI). HDRI is a recent technology allowing for capturing images with a much extended dynamic range whose values represent real-world luminance rather than just arbitrary pixel values. This article lays out the steps necessary to create HDR images, and highlights recent developments in the technology and its applic...

We stand on the threshold of a new era in digital imaging, when image files will encode the color gamut and dynamic range of the original scene, rather than the limited subspace that can be conveniently displayed with 20 year-old monitor technology. In order to accomplish this goal, we need to agree upon a standard encoding for high dynamic range (HDR) image information. Paralleling conventiona...

Color imaging technologies with higher dynamic range, wider color gamut, and greater bit depth require new and/or different ways of thinking about color. In particular, color appearance issues become more important. This paper discusses some recent research on the application of color and image appearance modeling to high-dynamic-range and wide-color-gamut imaging.

IN this lecture note, we describe high dynamic range (HDR) imaging systems; such systems are able to represent luminances of much larger brightness and, typically, also a larger range of colors than conventional standard dynamic range (SDR) imaging systems. The larger luminance range greatly improve the overall quality of visual content, making it appears much more realistic and appealing to ob...

in this regards first of all cross sectional anatomy of salivary glands and different diagnostic modalities such as ultrasound, cat scan, conventional mri and nuclear studies will be discussed. advanced mri modality such as dce (dynamic susceptibility enhanced) imaging will be introduced. then various pathologies of salivary glands including infectious, benign and malignant neoplastic processes...

background dynamic contrast-enhanced magnetic resonance imaging (dce - mri) has been widely used in the management of breast cancer, and its diagnostic value in breast imaging has been demonstrated. there have only been a few reports regarding the usefulness of pre-contrast imaging. knowledge about clinically significant findings of preoperative, pre-contrast t1 and t2 mr images will allow more...

In this paper we model the process of temporal adaptation of the human visual system to varying luminance conditions. An eye tracker is used to capture the location of an observer’s gaze in a high dynamic range image displayed on the screen. We apply a novel technique of eye tracker data filtering to avoid flickering caused by incorrect gaze estimation. Temporary adaptation luminance is then de...

A method for capturing high intensity dynamic range scenes with a low dynamic range camera consists in taking a series of images with di erent exposure settings and combining these into a single high dynamic range image. The combined image values are found by weighted averaging of values from the di erently exposed images on a per-pixel basis. This paper reviews existing weighting schemes and c...
