| Research Abstract |
We computed a quantity of macro plastic debris using a technique for detecting the pixels of colored plastic debris using photographs taken webcam installed at four Japan coasts and a projective transformation. The technique consists of the generation of color references using a uniform color space to detect plastic debris pixels, the removal of misdetected pixels by applying a composite image method. We successfully obtained a time series of the plastic debris quantity.
