<p>Image analysis system for analysis or enhancement of out of focus images. System is particularly applicable to measurement of fibre diameters by analysis of image captured by camera. The degree of focus or 'visual sharpness' of the image is measured using information about the magnitude and shape of light intensity profile at transect through a boundary or edge of the image. A measured dimension between two boundary segments, for example the width of a fibre image, is corrected according to the measured sharpness of focus and the magnitude of the measured dimension.</p> |
