针对传统提取信息方法的局限性和对唐代服饰进行信息提取自身的特点,提出了一种利用图片的灰度值作为深度信息的唐代服装褶皱信息提取方法.在计算机视觉OpenCV技术平台上,及其Photoshop图像处理技术上对提取服装褶皱信息的方法进行研究.在Photoshop中对图片进行预处理,然后在OpenCV平台上对图片进行褶皱信息提取,并将具体数据输出,并用Maya建模软件对输出的褶皱数据信息进行三维恢复,使唐代服装模型立体化重现.利用这种方法突破了传统建模方法只能对简单物体进行三维恢复的局限性,提高了建模效率,使模型达到逼真的三维可视化效果. 相似文献

为研究服装在实际着装过程中起皱的客观评价方法,以15块机织试样为研究对象,将其制作成试穿裤,进行实际着装起皱,然后对折皱图像进行主观评价,利用小波分析技术提取特征值,最后将小波特征值与主观评价及折皱回复角度进行对比研究。结果表明:小波分析的细节系数标准差与专家主观评价结果具有良好的一致性,可提取小波二层分解时水平方向的细节系数标准差作为取代主观评价的客观指标,以节约时间和成本;织物经向抗皱性对着装时服装抗折皱变形的贡献最大,斜向其次,纬向最小;采用折皱回复角表征织物抗皱能力时,建议增加斜向折皱回复角的测试,同时赋予经纬向不同的权重(经向大于纬向),以提高测试结果与实际着装时的吻合度。 相似文献

The textile and clothing industry has conventionally used subjective methods for the assessment of fabric wrinkling. Indeed, the fabrics were usually evaluated subjectively in reference to a set of visual standards. However, the visual assessments of the wrinkling degree, often showing inconsistencies between wrinkle judgments of observers, are severely influenced by the color and the fabric texture which may exist. In this paper, an objective method which permits an evaluation of multidirectional wrinkling of any colored fabric has been developed using digital image analysis. This method consists in capturing images of the color wrinkled fabrics and processing them in simple steps using image‐processing software. The surface roughness, density, width, length, number, and height of the wrinkles, considered as wrinkling characteristics, were extracted. Wrinkle degree was selected to use as the comparative parameter of the result evaluation from conventional and digital methods. The wrinkle grade of each fabric sample obtained through the conventional technique was statistically compared with that obtained through the digital technique developed. This study demonstrates that the results of the digital method developed for wrinkle evaluation of colored fabrics were similar to those of conventional methods of wrinkling evaluation. 相似文献

目前的抗皱性测试方法只能测试织物单一方向的折皱回复性,这与服装穿着时多方向的起皱形态相差较大。针对这种情况,本文首先设计一种能近似模拟服装膝盖和肘部起皱形态的多方向起皱装置,然后给出了其使用与测试方法,进而提出两个评价指标--急弹性和缓弹性抗皱面积比,最后将20块织物的这两个指标与急弹性和缓弹性折皱回复角进行对比分析,得出急弹性和缓弹性抗皱面积比分别与急弹性和缓弹性折皱回复角具有高度正相关关系。且多方向起皱装置所形成的折皱形态更接近服装实际穿着时的起皱形态,也能更好地反映织物的综合抗皱能力。 相似文献

文章通过MATLAB对棉绉织物表面图像进行处理,根据分形理论对棉绉织物表面的灰度曲面进行分形特征分析,利用计盒法计算灰度曲面的分形维数,以此评定棉绉织物表面纹理的粗糙度和起绉程度。实验结果表明:棉绉织物表面图像的灰度曲面具有显著的分形特征,分形维数与棉绉织物表面纹理的粗糙度和起绉程度密切相关。 相似文献

为了掌握衣下空间体积的规律,本文通过在标准体型人台上依次穿着面料不同、款式相同的服装,运用[TC]2 NX-16非接触式三维扫描技术采集点云数据,经过计算机图形处理和对比,立体再现衣下空间的存在,得到衣下空间的整体立体体积,逐步回归得出影响衣下空间的主要面料性能项目,以及这些项目共同作用于衣下空间大小的表达式。衣下空间与服装面料的性能有紧密关联性。衣下空间的大小与硬挺度.抗弯长度、经纱密度呈显著正相关,与悬垂度.波峰夹角均匀度呈显著负相关。该结论对服装的设计制作,尤其是功能防护服装的面料设计,可以起到先期预测并控制的作用。 相似文献

针对基于手绘草图的服装图像生成质量较低以及服装图像丰富的语义属性与视觉细节难以利用的问题,提出一种基于手绘草图的服装图像生成方法AGGAN。利用深度学习技术中的强大生成模型生成式对抗网络与注意力机制,对服装草图与服装图像数据进行学习,通过属性融入模块将服装属性进行One-hot编码后得到AdaIN参数并融入到生成对抗网络模型中,训练模型学习服装图像与其视觉属性之间的对应关系,使得模型能够在输入条件为服装属性的情况下生成相应的服装图像。对比了AGGAN与其它图像生成方法在输入为服装草图时生成服装图像的效果,结果表明:AGGAN的弗雷切特初始距离FID值得分相较于无监督图像生成模型CycleGAN降低了26.2%,初始分数IS值则提高了13.8%,明显提升了生成服装图像的多样性与保真度。 相似文献

Quantitative two-dimensional analysis of facial wrinkles of Japanese women at various ages 总被引:1,自引:0,他引:1

To evaluate individual differences in the recognition of facial wrinkles, we asked 40 Japanese female observers to identify wrinkles using transparent sheets over frontal facial photos of four females aged 20, 39, 55 or 75 years. We then measured the number and length of those wrinkles by image analysis. Wrinkles identified by those 40 observers showed aged-related increases in the standard deviation (SD) values for number and length but age-related decreases in the coefficient of variation (CV)%. Therefore, to clarify factors affecting the degree of wrinkle detection, wrinkles were identified by two groups of age-matched male and female observers, by two groups that differed by age, and by two other groups, one of which who felt that there was an improvement in their wrinkles after application of an antiwrinkle agent and another group who did not feel that there was any improvement after the same treatment. Improvement was observed by replica image analysis in all groups. The degree of wrinkles identified was not affected by the age or by the sex of the observer group. However, the group who felt that there was an improvement in their wrinkles after treatment with the antiwrinkle agent identified a significantly higher number of wrinkles than did the group who did not feel that there was an improvement. These results suggest marked individual differences in the recognition of wrinkles. Fine wrinkles in relatively young subjects are difficult to detect, but moderate to marked wrinkles in middle-aged and in aged subjects can easily be detected. Concerning the cause of individual differences in the extent of wrinkle detection, observers who identified a large number of wrinkles tended to recognize not only pronounced wrinkles but also recognized fine wrinkles as 'wrinkles'. This seems to have also affected their feelings about the success of treatment with the antiwrinkle agent. 相似文献

根据人体的着装部位,可以将成衣分割成为衣部件。基于衬衫部件重构的纸样设计即是利用不同号型的衣部件重组生成个体样版的方法探索。本文以女衬衫为例,基于结构设计纸样并将其分成矢量部件,以国标中号型配置为部件取值范围,对应控制部位尺寸进行匹对归号,然后选取个性体为样本,根据样本各部位所属号型从系列样版中提取部件样版,进行重构从而实现满足个体尺寸的个性化样版的生成。通过虚拟试衣初步验证了本方法生成样版的可穿性,并对实验数据进行数理分析,构建样版部件重构模型,为后期个性定制样版智能化生成提供理论依据和数据支持。 相似文献
