精纺毛织物缝纫平整度客观评价方法

精纺毛织物缝纫是否平整将影响毛制服装的品质，为探索客观评价精纺毛织物缝纫平整度的方法，将 6 块含毛纯色机织物按照不同的抽褶量，制作成 24 块缝纫平整度不同的试样。采用不同的方法对各试样平整度进行主观评价，之后将缝纫图像经过Gabor 变换，提取了不同方向、不同频率的熵值，接下来根据熵值最大的原则进行滤波器的筛选，得到 6个最优滤波器滤波后的总熵值作为客观评价指标。结果表明：总熵值与专家成对比较计分之间呈较好的二次方多项式关系；总熵值既可预测成对比较的主观得分，也可估算专家主观评价的缝纫平整度等级，Gabor 变换可用于精纺毛织物缝纫平整度的评估，且具有客观、准确的优点。

Objective evaluation of seaming smoothness for worsted wool garments

Seamsmoothness for worsted wool fabric will affect the quality of garments. In order to investigate the objective evaluation method of seaming smoothness for worsted wool fabric,6wool woven fabrics withsolid color were selected and gathered toproduce24 samples with different seam smoothness. The seamed samples were then subjective evaluation according to their smoothness with different methods.The images of the seamed samples were Gabor analyzed, and then the entropy values of different directions and different frequencies were extracted. After that, the filter was chosen by the principle of max entropy. At last, the total entropy value acquired by 6 best filters was obtainedas the objective evaluation index with the information fusion technology. Results show thatgood quadratic polynomial relationship exists between the total entropy and experts pair comparing score, and the total entropy value can be used to estimate the score of pair comparison as well as the seam smoothness grade level of experts subjective evaluation. Gabor transform can be used to evaluate the seam smoothness of wool apparel， which has the advantage of objectiveness and accuracy.
