Name
speedtest - CPU test for image processing
Synopsis
speedtest
Description
speedtest performs several classical image processing operations, and
reports the time spent on CPU. The following tests are applied:
uniformly distributed noise generation
filtering by 3x3 kernel convolution
filtering by 5x5 kernel convolution
median filtering with 3x3 kernel
statistics computation
fast fourier transform
resampling by a zoom factor of 2.0
speedtest starts by generating an image containing noise only, and then
performs all the above operations on this image, and outputs CPU times
for each test. CPU times are given for the total time in seconds and
the average per pixel time in microseconds. The total and per pixel
time are given for all the tests.
Notice that the given time values are only estimations, since they are
based on wall clock time, not on CPU time. Your results will vary
depending on the machine workload.
