Leather
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 کاملLeather bioprocess intensification: Ultrasound assisted novel enzymatic hair-loosening system for leather processing
The use of enzymes for hair loosening in leather processing provides a cleaner option. However, there is need to improve the efficiency of these unit operations involving bioprocess by way of process intensification techniques, such as, the use of ultrasound. In this paper, the use of ultrasound has been studied in native enzyme papain (A) based hair-loosening system and compared with commercia...
متن کاملFalse Position based Auto Exposure Algorithm for Properly Exposing the Leather Samples in the Leather Industries
In order to detect the defects in the leather sample in an automated way, the image of the leather sample has to be captured properly. To properly capture the images of the leather sample, we have implemented an auto exposure algorithm based on false position method which is discussed in this paper. This algorithm can also be used to properly expose the natural scenes
متن کاملAutomatic 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 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...
