基于小波能量的簇绒地毯跳纱疵点的检测方法

针对簇绒地毯中存在的跳纱类疵点提出了一种基于小波能量的疵点检测方法。该方法首先使用CCD相机对地毯图像进行采集,然后将采集到的地毯图像进行滤波处理,并用三层小波对其进行分解,通过提取分解得到的细节子图的能量值和正常地毯图像细节子图的能量值的比较来判断正在测试的图像中是否含有疵点;对于有疵点的地毯图像使用Otsu法进行阈值分割二值化,并进一步使用闭运算消除二值化图像中存在的噪点,突出疵点部分。最后通过实验验证了此方法的可行性,所提出的方法可以有效地将地毯图像中的跳纱类疵点检测出来。

The effects of drying parameters and conditioning on mechanical properties of latex‐backed carpet

In this study, the effects of drying parameters and conditioning on the mechanical properties of latex‐backed carpet were investigated. Mechanical properties clearly correlated with the lowest moisture content (MC) experienced by samples in either drying or conditioning. Lowering MC was necessary to develop mechanical properties; however, the highest mechanical properties were achieved at the highest latex temperature, indicating that raising latex temperature can improve mechanical properties. The effect of conditioning on mechanical properties depended on the MC of the latex backing at the end of drying.     

The design and initial evaluation of visual cues in carpets to assist walking

Prior research has shown that carpets assist walking thereby reducing the incidence and injury severity of falls, and that visual cues can assist walking. However, little attention has been given to the ability of visual cues in carpets to assist walking. Design guidelines were developed for the colouring and patterning of carpet to provide visual cues to assist walking. The guidelines took into account age-related visual impairments, and were applied in the preparation of a carpet. The designed carpet was compared with two carpets of standard designs in an impaired walking trial. The trial subjects reported a significant preference for walking on the designed carpet, suggesting that appropriate design of carpets can increase their contribution to the well-being of older people and others with impaired walking.     

Interactive genetic algorithm-aided generation of carpet pattern

Pattern generation for carpets is an expensive and time-consuming task that requires skills, imagination, and creativity. In recent years, interactive genetic algorithm (IGA) has been successfully utilized in generating patterns in different fields such as architecture, graphic art, and music among many others. In these applications, fitness functions cannot mathematically be defined, and the fitness value of each pattern combination is required to be evaluated by designer. Therefore, IGA can be utilized to serve as an effective tool to accelerate the design process. In the present work, a modified IGA is developed to generate patterns for machine-made carpets. Each pattern consists of a set of basic elements. Some basic pattern elements are collected, categorized, and coded as gene values. In each generation, new population is formed on the basis of observer's evaluation. All generated patterns are simultaneously shown for observer to assign a fitness value to each one. Hence, a new population can be achieved using the genetic algorithm. Our results show that acceptable patterns can be obtained after a limited number of generations. The system is designed in such a way that it can be used by unprofessional users.
