Abstract
A method of sensing including the steps of, (a) acquiring measurement values using a distributed optical fibre sensor; (b) arranging the measurement values in a matrix having at least two dimensions; (c) transforming each measurement value in the matrix to a corresponding pixel value on a predefined scale of pixel values and forming an image with pixels having the corresponding pixel values, wherein each pixel in the image is positioned at a position in the image corresponding to the position of the measurement value in the matrix; (d) processing the image using an image processing algorithm so as to reduce noise in the image to provide processed image; (e) transforming each pixel value of pixels in the processed image to values to provide measurement values with reduced noise.
