Artificial Vision Inspection Applied to Leather Quality Control
The paper deals with the problem of pointing out and mark the various kind of defects (mainly scars, wrinkles and fire brandings) of tanned calf leathers used in many industrial areas (e.g. household couches and car seats lining ones). In the first experiments here presented the authors try to use the same inspection method previously successfully applied to quality control of hands-made satin ...
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 کاملEstimation of pigment magnitudes in synthetic leather by using scanner and artificial neural network
In the present work the magnitudes of pigments in the synthetic leather, were measured by means of scanner. Initially synthetic leather samples pigmented by three different pigments of yellow, blue and red colors were prepared. Then the pigmented samples were scanned, and the values of RGB of images were calculated. The artificial neural network (ANN) method used to make relation between RGB va...
متن کاملN-N-dimethylformamide concentration in environmental and alveolar air in an artificial leather factory.
N-N-Dimethylformamide was determined every hour during the eight hours of the work shift in the alveolar air of eight workers employed in an artificial leather factory and in the breathing zone of the eight workers. The alveolar ventilation of each worker was measured for 10 minutes during the work shift. Alveolar dimethylformamide concentration (Ca) was correlated with the environmental concen...
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...
