It is the art of putting together effective display designs and ideas in order to boost store traffic and sales. It’s also a way to engage with customers and influence their purchasing decisions. A fashion trend occurs when a particular item, silhouette, color, or other new look rises in popularity. It changes with the seasons, and the store serves as a hub for communicating these changes to potential customers. Because items must be sold within a certain time frame, several display tactics are used to best present the merchandise and communicate the current fashion trends to customers. Visual merchandising becomes a key aspect of difference from merchants in the same category as retail firms, particularly fashion brands, try to compete in an already saturated market. Effective branding is now a vital success component for all types of fashion firms. Fashion brands may use effective branding tactics to build equity, promote consumer brand loyalty, and increase profitability. Visual merchandising is critical for inferring various customers’ perspectives and adding value to businesses. Its major goal is no longer to make items appealing in order to sell them quickly;it is rather to stand out, develop the correct brand image, and give the greatest possible customer experience. Visual merchandising aspects, when employed correctly, can infiltrate the buyer’s brain and prompt them to generate a favorable opinion of the store, allowing it to leverage its brand image. In this context, this research review focuses and aims to study the link between visual merchandising and Apparel Fashion trends, to study the relationship between visual merchandising and fashion branding and to find out the research gaps and scope for future research directions in the area of visual merchandising applied in fashion apparel industry.展开更多

文摘识别非驾驶行为是提高驾驶安全性的重要手段之一。目前基于骨架序列和图像的融合识别方法具有计算量大和特征融合困难的问题。针对上述问题,本文提出一种基于多尺度骨架图和局部视觉上下文融合的驾驶员行为识别模型(skeleton-image based behavior recognition network,SIBBR-Net)。SIBBR-Net通过基于多尺度图的图卷积网络和基于局部视觉及注意力机制的卷积神经网络,充分提取运动和外观特征,较好地平衡了模型表征能力和计算量间的关系。基于手部运动的特征双向引导学习策略、自适应特征融合模块和静态特征空间上的辅助损失,使运动和外观特征间互相引导更新并实现自适应融合。最终在Drive&Act数据集进行算法测试,SIBBR-Net在动态标签和静态标签条件下的平均正确率分别为61.78%和80.42%,每秒浮点运算次数为25.92G,较最优方法降低了76.96%。
