This paper was written to analyze the relationship between the water qualities of the lagoon which treats animal wastewater and their effluent images. Images were augmented by centrifuging each water sample to make a wide range of water qualities. Machine learning methods such as Ridge regression were introduced to investigate the relation between the RGB channel analyses of the water images and their water qualities.
The increase in centrifugation time was equivalent to reducing the chemical elements in the sample. Some parameters had insignificant relations, but total solids and total coliform showed significant relations. With this method, water images would be able to predict the water quality.
3. Application to research
Most of computer vision analysis were conducted using CNN algorithms. But in this paper, RGB channel analysis were introduced. I can consider this way as one of the image analysis methods.
