Image-Processing

Using image processing to test some interest expriment.

Run

• Way 1 (Base on Makefile + execute.sh)
  • make : get the original data structure (RGBTRIPLE) to operate.
  • avaliable target:
    • gau_all : run all types of gaussian blur functions on image.
    • mirror_all : run all types of mirror functions on image.
    • hsv : run all types of hsv functions on image.
  • Run/check performance:
    • make run : run the program and get and show the image.
    • make perf_time : run the program with all function execution, and output the execution times.
• Way 2 (Base on image_process.sh)
  • Using shell script to choose compile arguments
  • bash image_process.sh [-o ... ] [--option ... ]
  • short option: -o
    • -a : compile with all gaussian function (= gau_all , = -g 2047)
    • -e : use when compile with ARM environment (TODO)
    • -v : use when want to compile with valgrind (Can't use with perf)
    • -t : use when you only want to compile and run the test module part.
    • -m : compile with all mirror function
    • -h : compile with all hsv function
    • -s : use when you want to compile with strictly option (-Wall -pedantic)
    • -g N : choose specific gaussian function to run, using N to distinguish ; if N = combination of any type of N below, the program will generate all elements in combination.
      • 1 : SSE + pthread on original structure
      • 2 : SSE on split structure
      • 4 : SSE on original structure
      • 8 : SSE + prefetch on original structure
      • 16 : naive + unroll on split structure
      • 32 : naive + unroll on original structure
      • 64 : pthread + unroll on split structure
      • 128 : naive 1-dim + unroll on split structure
      • 256 : naive + expand on split structure
      • 512 : naive on split structure
      • 1024 : naive on original structure
      • 2047 : all function will be use one
  • long option: --option
    • --perf N: compile and apply N times perf on program.
    • --clean : same function as make clean
    • --help : list usage

Another Usage

• execute.sh : let user edit the argument(with "enter = default") , call by make run , depend on with type of executed file that user compile.
• scripts/plot_time.gp : gnuplot script.
