This is the sample app for the blog post at:
https://nerves.build/posts/ocv_photo_analyzer
In order to run the project you must set the following value
config :ocv_photo_analyzer_example, Photos.Photo, base_path: "APP_DIR/priv/static/uploads"
You can change the location of the uploaded photos if you like through this config:
config :upload, Upload.Adapters.Local, storage_path: "priv/static/uploads", public_path: "/uploads"
You can also control the values ocv_photo_analyzer uses for determining dominant colors. These are the default values:
config :ocv_photo_analyzer, OcvPhotoAnalyzer.Analyzer, clusters: 5, iterations: 10, attempts: 5, precision: 0.1, analysis_size: 1000
The details of these parameters are discussed here: https://docs.opencv.org/2.4/modules/core/doc/clustering.html
