Akyuz’sworkasanefficiencybenchmark for the OpenCL implementation we
present in this chapter.
Perhaps the most closely related work to ours is that by Chris McClana-
han [McClanahan 11]. McClanahan created a Linux and Android application
that uses a single video camera to create tone-mapped HDR images in real time.
The implementation uses OpenCV and OpenMP but does not appear to include
a GPGPU implementation. Furthermore, the frame rate of the Linux implemen-
tation is very low, even on low-resolution images. Nevertheless, McClanahan’s
work provides a benchmark against which we can compare. ...
