High Dynamic Range images under Linux Not all image files are created equal. Most of us know this from working with the everyday formats like PNG, JPEG, and TIFF, each of which has its own pros and cons. But cutting-edge applications from cinematography to computer vision demand more range, color depth, and accuracy than these formats can deliver. You may have seen the HDR acronym in reference to computer gaming as well. ... but some are less equal than others The trouble with older image formats is that they were designed with output devices in mind. Today, most of our entertainment media are being created and processed on computers. While we could modify existing image formats by tacking on extra pixels, researchers and industry people opted for a better idea: try to define an image format that can describe the entire scene in at least as much detail as the human eye can resolve -- even if it can't all be displayed on today's equipment. HDR image formats all have a few points in common. The formats The software

IDS Imaging Development Systems - Home 3D Texture 3D Surface Recovery using a Flatbed Scanner Results The ability to acquire descriptions of surface topography and reflectance of real-world textures both simply and cheaply would be of great value. In conjunction with bump, texture and displacement mapping computer graphics techniques, these data enable the realistic rendering of real-world textures in virtual 3D scenes. Figure 1 Flatbed scanner Figure 2 3D Plot of a texture's height map The algorithm merely requires four input images of a texture acquired with a scanner such as that in Figure 1 to produce 3D texture data such as the height plot in Figure 2. Figure 3 Relight data: normal, height, albedo maps Figure 4 Animation of relit texture For further information regarding this patent-pending technology, please contact Prof.
Technology Review: Color Matching by Phone Hewlett-Packard (HP) Labs has unveiled a research project that could help people select colors when shopping for products. The technology uses color-correcting and computer-vision algorithms that reside on HP servers. The idea, explains Nina Bhatti, principal scientist at HP Labs, is that consumers use their mobile phones to take pictures of themselves or objects, and then send these pictures to HP servers. Within seconds, the consumer receives a text message with a color recommendation for matching makeup to skin tone, or for finding the right paint hue for the home. The research prototype that Bhatti and her team developed is specifically designed to help people find the best shade of makeup based on their skin tone. Using HP’s prototype, a consumer simply takes a picture of herself while holding a color-reference chart that could be provided at the makeup counter at stores, in catalogues, or in magazines.

Dynamic Photo HDR, high dynamic range imaging software with Anti-Ghosting Dynamic Photo-HDR is a next generation High Dynamic Range Photo Software with Anti-Ghosting, HDR Fusion and Unlimited Effects Powerful alignment and deghosting tools for high-dynamic-range generation, six tone mappers, plus lots of postproduction adjustments make MediaChance's Dynamic Photo HDR a real winner for HDR imaging. Create magical scenes from ordinary images “Not only is DPHDR one of the more affordable free-standing High Dynamic Range and Tonemapping titles, it is also powerful enough to warrant serious consideration for the HDRI photographer.” JACK HOWARD for Popular Photography DPHDR6 software goes far beyond the HDR tone-mapping task. Version 6 interface has been fully redesigned. Version 5 was fast. This is where DPHDR6 really shines. Every part of the process can be repeatwed in the new Batch Processing. DPHDR6 works equally happy with a single image or a series of bracketed images. Latest Updates: 6.01 (3/5/2015) - fix for files drag & drop, keyboard in image browser
HDR Image and Video Processing -- Max-Planck-Institut für Informatik Tremendous progress in the development and accessibility of high dynamic range (HDR) technology that we witness in recent years creates many interesting opportunities and challenges in computer vision, image processing and graphics. The goal of this web page is to provide information on a complete pipeline for HDR image and video processing from acquisition, through compression and quality evaluation, to display. We include links to relevant papers and project pages. We also provide source code of tools useful for HDR image and video manipulation.
