White specks (undyed neps) in dyed fabric samples are a quality problem that arises from neps of immature cotton. Dr Grant's research aimed to correlate the white speck neps back to fibre properties and gin parameters. The number of white speck in a fabric sample were being measured at the USDA by first scanning a sample of fabric (approximately A4 size) using a commercial computer scanner and then the image analysed to determine the number of white specks(neps) using specially written software. Project changed direction with new approach evolving which was successful. Work taken up with CTFT5
