Preprocessing: Temporal downsampling

Example code to run the downsample test function with the following commands:

loadRepoFunctions;
testMovie = loadMovieList('pathToMovieFile');
unitTestDownsampleMovie(testMovie,'interp1Method','linear','cropSize',5);

Below is an example pixel from a cell in a BLA animal. Note...

  • ImageJ Scale...+bilinear+averaging (blue) and Matlab imresize+bilinear (red) both produce pretty much identical results.
  • imresize using bilinear and bicubic produce similar results with bicubic having slower runtimes (e.g. on my machine 3.46 vs. 4.31 sec if set cropSize to 100).
  • The number next to each name is the vector's variance. image
