摘　　要：为提高洗后织物外观平整度主客观评级的一致率,提出了基于视觉特征编码与多分类支持向量机相结合的织物折皱自动评级方法。首先,将6块立体标准样板扩充至450幅具有代表性的织物洗后折皱图像作为训练集;其次,模拟人眼视觉聚焦机制,利用稀疏编码技术,分别解析9个半级图像子库的多尺度编码特征,并构建形成各级特征向量链码;最后,利用线性多分类支持向量机算法评定其余200幅测试样本。实验结果表明:该方法主客观一致率为95.1%,评级精度为0.1级,单样本评级速度小于6 s,能够满足当前织物整理剂、洗涤剂、洗护设备等护理效果的商用评级用途。In order to improve the consistency between subjective and objective ratings for the repeatedly laundered fabrics,an automatic method of wrinkling assessment based on visual feature coding and multiclassification support vector machine( SVM) was proposed. 450 representative wrinkled fabric images including 6 standard samples were selected as the training set. In addition,the human visual focusing mechanism was simulated,and the sparse coding method was utilized to extract the feature vector chain codes from 9 half-level image sub-databases. 200 wrinkled images as testing samples in this experiment were classified by linear multi-classification SVM. Results show that consistency between subjective and objective rating reaches 95. 1%,rating precision is 0. 1 and rating speed for single sample is less than6 seconds,which meet the current commercial rating requirement for effective evaluations of fabric finishing,detergent products and care equipment.
