High Dynamic Range (HDR) displays and cameras are paving their ways through the consumer market at a rapid growth rate. Thanks to TV and camera manufacturers, HDR systems are now becoming available commercially to end users. This is taking place only a few years after the blooming of 3D video technologies. MPEG/ITU are also actively working towards the standardization of these technologies. How...

The mammary gland undergoes significant proliferative stages after birth, but little is known about how the developmental changes impact DNA double-strand break (DSB) repair. Mutations in multiple genes involved in homology-directed repair (HDR), considered a particularly accurate pathway for repairing DSBs, are linked to breast cancer susceptibility, including BRCA2. Using reporter mice that e...

In video games, High Dynamic Range (HDR) rendering is commonly used and allows us to render more photo-realistic looking images. HDR rendering uses a tone-mapping process to achieve a Low Dynamic Range (LDR) rendering result for a display. The process compresses or clamps HDR color information to fit LDR devices which typically have an 8-bit color resolution. There are a lot of tone-mapping alg...

BACKGROUND The literature supporting high-dose rate brachytherapy (HDR) in the treatment of cervical carcinoma derives primarily from retrospective series. However, controversy still persists regarding the efficacy and safety of HDR brachytherapy compared to low-dose rate (LDR) brachytherapy, in particular, due to inadequate tumor coverage for stage III patients. Whether LDR or HDR brachytherap...

In theory HDR photography generated from exposure sequences is limited to pictures of still scenes preferably taken with the camera mounted on a tripod. Current state-of-the-art HDR imaging software relaxes this limitation by aligning the pictures with affine transformations. However, two pictures cannot be aligned with a single affine transformation if objects in the scene move or the position...

High-dynamic-range (HDR) images can be created with standard camera hardware by capturing and combining multiple pictures, each sampling a different segment of the irradiance distribution of a scene. This seemingly straightforward process involves several important steps, which will be the focus of this chapter. We start by examining the problem of selecting the set of exposures that properly m...

In this paper we propose a new dataset for evaluation of image/video quality metrics with emphasis on applications in computer graphics. The proposed dataset includes LDR-LDR, HDR-HDR, and HDR-LDR reference-test video pairs with various types of distortions. We also present an example evaluation of recent image and video quality metrics that were applied in the field of computer graphics. In th...

In this digital world, everything including documents, notes is kept in form. The requirement of converting these documents into processed information demand. This process called as Handwritten digit recognition (HDR). scan document and classified to identify the hand written words text so that it can be used keep format means computerized font everybody read properly. paper, discussed classifi...

We evaluated the reproducibility and validity of an FFQ used in a Chinese community-based nutrition and health survey. A total of ninety-nine males and 104 females aged 31-80 years completed four three consecutive 24-h dietary recalls (24-HDR, served as a reference method, one three consecutive 24-HDR for each season) and two FFQ (FFQ1 and FFQ2) over a 1-year interval. The reproducibility of th...
