An analysis of gloss components in image signals

为了保证光泽度信息显现的可能性，我们提出了一种证明光泽度成分存在的方法，并利用带有电视的自然图像揭示其特征。我们将有光泽的物体与没有光泽的物体进行比较，假设喷了油的物体是有光泽的物体。我们将图像分成几个小区域，计算每个区域的平均值和密度变化的频率分布。结果表明，光面图像中的分布并不均匀，并且被分成几个组。在HLS颜色坐标中，光泽度的分布区域与LS平面上的光泽度强度成比例地扩大。通过这些实验，我们证明了有可能检测到光泽成分。在具有HLS分量的三维空间中，我们使用从图像元素周围信息获得的矩阵来识别光泽映射的存在，并将该映射识别为分段线性映射。

To ensure the possibility of developing gloss information, we would like to propose a method to prove existence of a gloss component, and reveal its characteristics using natural images with television.We compare a glossy object with an object without gloss on the assumption that an object sprayd with oil is a glossy object. We separate an image into small several regions and calculate the frequency distribution of the average value and the density variation in each area.The results concluded that the distribution in a glossy image was not uniform and was separated into several groups. In an HLS color coordinate, the distribution area of gloss expands in proportion to gloss strength on th LS plane.We showed that there was the possibility of detecting a gloss component through these experiments.In a three dimensional space having HLS components, we recognized the existence of a gloss map using a matrix obtained from information around a picture element, and identified the mapping as piecewise lineare mapping.
