This paper introduces a new approach for optimum auto exposure (AE) based on the high-dynamic-range histogram (HDH) of a scene. The exposure control is optimal in terms of recorded information of the scene. The advantages over AE based on mean values of images will be shown as well as a proof of concept implementation and results. Futhermore possible extensions to this approach are discussed. T...

We present a new approach to display High Dynamic Range (HDR) video using gradient based high dynamic range compression. To obtain HDR video, we utilize the split aperture camera. We apply a spatio-temporal gradient based video integration algorithm for fast and accurate integration of the three input HDR videos into a low dynamic range video, which is suitable for display. The spatiotemporal v...

There are a variety of techniques for combining the three different images into a single image, but the main limitation is the dynamic range of the media that the photo will finally be displayed on. Paper and digital monitors, like digital sensors, are “low dynamic range” devices, and thus cannot demonstrate the greater dynamic range that has been captured. Tonemapping is one process by which h...

We report a concept to increase the dynamic range of capillary driven microfluidics for use in point-of-care diagnostics [1]. The chip uses one-pipetting step of 20 μL of human serum spiked with C-reactive protein (CRP) at 100 ng/mL. A four-fold increase in signal strength is achieved by varying the flow rate in six different reaction chambers.

purpose ankle sprain is one of the most common injuries among athletes and instability and injury to this joint is responsible for long time loss of physical and recreational activity. also, it can impose high costs to sport teams. prevention of this injury is an important concern of practice and rehabilitation. one way of reducing the possibility of ankle joint injury is using an ankle orthosi...

the motivation of this paper is to propose such equitable method for ranking all decision making units (dmus) in dynamic data envelopment analysis (ddea) framework. as far as we are aware there is not more studies in dynamic dea literature. what's more, in such cases the best operating unit is important to be sampled for the others in under evaluated time periods. however, in this special conce...

dynamic assessment (da) which is rooted in vygotsky’s (1978) sociocultural theory involves the integration of instruction and assessment in a dialectical way to achieve two main purposes: enhancing learners' development and understanding about their learning potential. however, the feasibility and appropriateness of mediation are two main concerns of da. the former is concerned with the applica...
