Technical Abstract: White specks are fiber clusters that appear as small white flecks on dyed fabrics. Their minute size and depth of shade, increases the subjectivity and complexity. No standard methods exist to quantify the level of white specks. Image analysis was evaluated as a means to measure white specks in order to remove the subjectivity from the dye defect classification. This paper provides systematic procedures for the evaluation of white speck on dyed fabrics. Software, hardware and methods to obtain the white speck count, average size and percent white are discussed in detail. Optimas 5.2 software program utilizes a computer, two monitors, a video camera and a photographic camera stand. The study involved eight plain weave fabrics each with visually distinct levels of white speck content. These fabrics were initially used to identify the system, and software best suited for white speck quantification. The manual thresholding method was precise for one operator, but showed significant differences between operators. The fabrics were evaluated for their white speck content using the manual thresholding method (very operator dependent), and again using the new auto-thresholding method to minimize operator input. The auto-thresholding method used light meters to maintain constant lighting levels and then automatically sets the threshold levels. The system detected different levels of white specks for these fabrics as expected. The auto-thresholding method was much more accurate in actual count of white specks than the the manual method. This measurement system gives the textile industry a standard tool and procedure to measure fabric appearance.
