- Apply a 5×5 Laplacian filter to images with PGM format (Laplacian of an image is often usedfor edge detection).
- Analyse and compare the performance of CPU execution and GPU execution for different kernels on this program.
- $ mkdir build
$ cd build
$ cmake ../
$ make - $ ./pgm_creator.out <width> <height> <output_filename>
To create a random PGM image given width and height. - $ ./main -i <input_file> -o <output_file>
To run the program and printout the performance of CPU execution and GPU execution for different kernels.
