视觉表征ACTS模式下的华为海外宣传片研究

随着经济全球化的快速发展,品牌形象成为一个企业利益的重要体现。广告宣传片是解读和阐释品牌形象的直接途径。由于宣传片具备影像制作的众多优势,可以极大地推广某一品牌,因此各大企业都越来越重视广告宣传片的制作和传播。本文以华为海外宣传片Dream It Possible为例,运用视觉表征ACTS模式,对其进行视觉阐释,分析其文本蕴含的深层意义。

我国传统体育的图像表达困境

采用视觉表征ACTE模式作为分析工具,从吸引注意、引向内容、展现主题和配置效率等4个层面解析以武术为代表的传统体育具体构图元素,探讨传统体育图像文本的传播效果和构建方法。结果显示:传统体育的图像表达面临困境,具体表现为优质推广平台稀缺、符号性动作匮乏、主题表述式微以及图像配置手段单一。建议:推动传统体育的图像表达从历史表述走向想象建构;从典型符号、解说框架、次级文本、图像配置等方面实现传统体育电视传播的框架结构。

Wear Debris Identification Using Feature Extraction and Neural Network

A method and results of identification of wear debris using their morphological features are presented. The color images of wear debris were used as initial data. Each particle was characterized by a set of numerical parameters combined by its shape, color and surface texture features through a computer vision system. Those features were used as input vector of artificial neural network for wear debris identification. A radius basis function (RBF) network based model suitable for wear debris recognition was established, and its algorithm was presented in detail. Compared with traditional recognition methods, the RBF network model is faster in convergence, and higher in accuracy.
