HDTR | High Dynamic Time Range Images
capturing the flow of time in a single frame
The code to create the HDTR images on this site is written in Perl. If you're on a UNIX system, chances are Perl is already installed. For Windows, use ActiveState Perl.
You will require the following modules (see CPAN, or use the ActiveState ppm package manager).
The script comes with
- set of input images
- several configuration files
- sample HDTR images
tar -xvfz makehdtr-0.1.tgz cd makehdtr-0.1.tgz /usr/bin/perl makehdtr -conf image-01.conf # extra debug information /usr/bin/perl makehdtr -conf image-01.conf -debug
Depending on the amount of blending, HDTR image creation can take several minutes. For example, on an Opteron 248 system with 1 Gb or RAM, image-01.jpg takes 55 seconds.
configuration | basic HDTR with no blending.
configuration Added time stretch.
stretch_time = yes time_blend_a = 0.75
configuration Added spatial blending
spatial_blend = yes blend_dist = 0.5 blend_a = 1
configuration Added temporal blending
weights = 1,2,4,2,1
configuration Changed time flow direction
flowaxis = y flowdir = 1
