The tool set pfscalibration allows for the calibration of the camera used to take the pictures and the recovery of HDR images from the multiple exposure images. The tool set, pfstools, provides a set of tools for reading and writing HDR images. The pfstmo tool set allows for tone-mapping operators to be applied to HDR images, producing images which may be displayed on a LDR display device. This software contains the gradient domain compression scheme, along with a number of other tone mapping operators. Project Description The objective of this project is to automate the process of taking high dynamic range (HDR) images using a conventional low dynamic range (LDR) camera. An HDR image is able to capture a much higher level of detail than a LDR image, as it is able to capture a much wider dynamic range of intensities than a regular LDR image is able to. To obtain a HDR image from a standard digital camera, a series of pictures must be taken at a variety of shutter speeds. The GUI provides a user friendly tool to send appropriate commands to the camera.
