It is a challenge for Phase Measurement Profilometry (PMP) to measure objects with a large range of reflectivity variation across the surface. Saturated or dark pixels in the deformed fringe patterns captured by the camera will lead to phase fluctuations and errors. Jiang et al. proposed a high dynamic range real-time 3D shape measurement method without changing camera exposures. Three inverted...

Pictures can be drawn by hand, or imaged by optical means. Over time, pictures have changed from being rare and unique to ubiquitous and common. They have changed from treasures to transients. This paper summarizes many picture technologies, and discusses their dynamic range, their color and tone-scale rendering and their spatial image processing. High Dynamic Range (HDR) image capture and disp...

High dynamic range (HDR) imaging techniques address the need to capture the full range of color and light that the human eyes can perceive in the real world. HDR technology is becoming more and more pervasive. In fact, most of the cameras and smartphones available on the market are capable of capturing HDR images. Among the challenges posed by the spread of this new technology there is the incr...

High dynamic range (HDR) imaging seems to have developed to a level of soon being a standard feature in consumer cameras. This study was motivated by the need for evaluating tone mapping operators especially for consumer imaging applications. A no-reference method based on ISO 20462-2:2005 triplet comparison was created for evaluating tone mapping operators. Multiple HDR test images were photog...

Implantable image sensors have several biomedical applications due to their miniature size, light weight, and low power consumption achieved through sub-micron standard CMOS (Complementary Metal Oxide Semiconductor) technologies. The main applications are in specific cell labeling, neural activity detection, and biomedical imaging. In this paper the recent research studies on implantable CMOS i...

This paper proposes a data hiding method for high dynamic range images with the LogLuv encoding format. To the best of our knowledge, this is the first data hiding algorithm developed in the literature for such an HDR format. Our scheme considers both the luminance channel and two chromatic channels when we embed a secret message. This allows us to conceal up to 6 bits of secret messages in the...

Over the last decade, much research experience has been gained in the realm of high dynamic range imaging (HDRI). On account of the significantly improved visual experience that HDRI offers, industry has recently taken a strong interest in this set of technologies. This is evident in the active consideration of HDR by standardization bodies, for instance DVD and EBU in the context of UHDTV, and...

High dynamic range imaging aims at creating an image with a range of intensity variations larger than the range supported by a camera sensor. Most commonly used methods combine multiple exposure low dynamic range (LDR) images, to obtain the high dynamic range (HDR) image. Available methods typically neglect the noise term while finding appropriate weighting functions to estimate the camera resp...
