Automatic visual inspection for leather manufacture
The visual inspection system was developed for defects detection on leather surfaces, which is an important component of automatic CAD/CAM cutting systems. The main functions of the system are quality control and raw material cutting. An efficient algorithm, which combines multiresolution approach, energy and entropy matrices, is presented for detection of defects embedded in leather surface im...
متن کاملA Novel Nano-SiO2 Tannage for Making Chrome-Free Leather
A novel pickle less combination tannage based on nano-SiO2 and oxazolidine as a substitute for chrome tanning has been developed. The size and distribution of nano-SiO2 in protein, the hydrothermal stability, the mechanical properties and the antifungal effect of final leather as well as the evaluation of eco-friendly characteristics of combination tannage were investigated. Scanning Electric M...
متن کاملLeather
Leather is derived from the hides of skins of animals. It is a remarkably durable, strong and versatile material, which in its various forms has been made into objects ranging from African shields and drums to European saddles and kinky underwear. From as early as 2700 BC until fairly recently leather was also in the forefront of information technology with its use (as skins, vellum and parchme...
متن کاملPreliminary Results on the Use of Leather Chrome Shavings for Air Passive Sampling
A new passive sampler based on low-density polyethylene (LDPE) layflat tube filled with chrome shavings from tannery waste residues was evaluated to determine volatile organic compounds (VOCs) in indoor and outdoor areas. VOCs were directly determined by head space-gas chromatography-mass spectrometry (HS-GC-MS) without any pretreatment of the sampler and avoiding the use of solvents. Limit of ...
متن کاملLeather Inspection Based on Wavelets
This paper presents a new methodology to detect leather defects, based on the wavelet transform. The methodology uses a bank of optimised filters, where each filter is tuned to one defect type. Filter shape and wavelet sub-band are selected based the maximisation of the ratio between features values on defect regions and on normal regions. The proposed methodology can detect defects even when s...
