    percentage area calculation

    Hi Guys,

    I need help working out the percentage area covered by fibres deposited on a 1um square area.

    Any ways of going about calculating this would be greatly appreciated.

    Image of fibres deposited on a surface is attached

    Thanks

    You should use a software that can differentiate the colors. (Photoshop could do the job I think)
    Then you divide the number of red pixels by the number of pixels.
