PCT No. PCT/GB91/00536 Sec. 371 Date Dec. 3, 1992 Sec. 102(e) Date Dec. 3, 1992 PCT Filed Apr. 5, 1991 PCT Pub. No. WO92/08967 PCT Pub. Date May 29, 1992.A method for inspecting garments for holes includes front-lighting the garment against a contrasting background and forming a pixel image thereof, isolating garment pixels from background pixels by automatically selecting an optimum binarization threshold grey level, binarizing the image at that level, determining the garment boundary, testing for consistency of grey level within the garment boundary on the binarized image along rows and columns of pixels within the garment boundary and noting inconsistent pixels, and identifying as holes only pixels which have been noted as inconsistent in both horizontal and vertical tests.
