ComputeLibrary
Installation
You can install ComputeLibrary from:
Tests
neon_cartoon_effect
You need an input image at PPM format. You have some in /usr/share/ComputeLibrary/sample-data/images/, from ComputeLibrary-sample-data package.
Run the following command:
neon_cartoon_effect myimage.ppm
And you will get myimage.ppm_out.ppm as a result (in the same folder as myimage.ppm)
More information on how it works can be found here https://community.arm.com/developer/tools-software/graphics/b/blog/posts/cartoonifying-images-on-raspberry-pi-with-the-compute-library
neon_convolution
You need an input image at PPM format. You have some in /usr/share/ComputeLibrary/sample-data/images/, from ComputeLibrary-sample-data package.
Run the following command:
neon_convolution myimage.ppm
And you will get myimage.ppm_out.ppm as a result (in the same folder as myimage.ppm)
neon_scale
You need an input image at PPM format. You have some in /usr/share/ComputeLibrary/sample-data/images/, from ComputeLibrary-sample-data package.
Run the following command to resize (half sizes):
neon_scale myimage.ppm
And you will get myimage.ppm_out.ppm as a result (in the same folder as myimage.ppm)
graph_alexnet
This test is based on this article: https://community.arm.com/developer/ip-products/processors/b/processors-ip-blog/posts/running-alexnet-on-raspberry-pi-with-compute-library
Once ComputeLibrary is installed, please download compute_library_alexnet.zip and extract it to assets_alexnet/ folder.
Run the following command:
export PATH_ASSETS=./assets_alexnet graph_alexnet --data=$PATH_ASSETS --image=$PATH_ASSETS/go_kart.ppm --labels=$PATH_ASSETS/labels.txt
and you will get:

You can also try other images from the list: go_kart.ppm, gold_fish.ppm, gondola.ppm, school_bus.ppm
If you want to use your own image, you must convert it to a 227x227 PPM image. For this operation, you can use ImageMagick:
convert square_image.jpg -resize 227x227 myimage.ppm
