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 follow-
ing 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.
