Does anyone have any experience with using the 16-bit floating-point type in an application. This relatively new data type is used in computer graphics. It's defined by several specs: OpenEXR, DirectX and the new IEEE-754 2008 standard. At WinHEC 2008 Microsoft's Chas Boyd had a presentation evangelizing this data type. (I wasn't ...
In the past I've saved RGB images (generated from physical simulations) as 8-bits/channel PPM or PNG or JPEG. Now I want to preserve the dynamic range of the simulation output, which means saving a floating point image and then treating conversion to 8-bits/channel as a post-processing step (so I can tweak the conversion to 8-bit withou...
i want to reuse an image multiple times within an item renderer, is it possible to embed the image and then reuse multiple times without having to go back to the server for the image? Is this the most performant solution? ...
I've found a PPM image with the header starting with PF (instead of standard P6, P5, P4, ... signatures). The resolution number is stored in floating point (-1.000). No comments are inserted to get how it was produced. Because the resolution, I derived that each pixel is composed by 12 bytes (4 bytes per component)... I suppose they are...
Hi All, So I'm doing some research related to High Dynamic Range Imaging (HDRI). I've already done some work in OpenCV related to aligning and ghost removal (no actual HDR manipulation or creation yet), and now I would like to be able to start working with HDR images. Can anyone recommend a good open source HDR library that would idea...
Hi All, I'm trying to get pfstools (as well as pfstmo and pfscalibration) working under Windows. These are basically an open source series of command line tools for High Dynamic Range (HDR) imaging. They were developed for Linux, so the documentation says that in Windows they need to be compiled and run in Cygwin, which is not a big d...
Hi Do you know any algorithm to create HDR images, like photomatix or photoshop "merge hdr" function? ...
