It is considered that the intensity value of each image pixel is the product of illumination function and ground object reflection, and the shadowed regions on the image are mainly caused by the short of illumination, so the information compensation for the shadowed regions should concentrate on the illumination adjustment of concerned area on the basis of the analysis of whole image. The shadow detection and compensation procedure proposed by this paper consists of four steps.展开更多

In most cases, however, only a single non-metric photograph is available, which is usually obtained either by an amateur, such as a tourist, or from a newspaper or a post card. To evaluate the validity of 3D reconstruction from a single non-metric image, this study analyzes the effects of object depth on the accuracy of dimensional shape in X and Y directions using a single non-metric image by means of simulation technique, as this was considered to be, in most cases, a main source of data acquisition in recording and documenting buildings.展开更多

Selective fragrances make up one of the primary categories of the so-called accessible luxury consumed by a middle class that is seeking to approach the upper classes by copying their lifestyle. Despite the importance of this market, there is relatively little literature existing in regards to the study of the image of luxury brands due to the complexity of the luxury phenomenon. This article presents the results of an initial qualitative study conducted on focus groups of luxury fragrance consumers, making it possible to identify the types of attributes to be considered when studying the brand image of said luxury products. Subsequently, a quantitative study was conducted in order to determine the perceived image of the principle luxury fragrance brands by consumers. Thanks to this study, it has been possible to determine the typical profile of each of the analyzed brands so that a subsequent comparison may be made with the advertising created by said brands in order to verify whether or not the image projected in their advertising corresponds with the perceived image of their target audience.展开更多
