摘要

本文提出了一种彩色图像处理的数学模型。它是对数型的。我们将立方体(- 1,1)3视为颜色空间的值集。我们定义了两个操作:加法(+)和实标量乘法(x)。通过这些操作，颜色空间变成了一个真正的向量空间。然后定义标量积(.|.)和范数||·||，得到一个(对数)欧氏空间。我们展示了如何使用该模型进行彩色图像增强，并给出了一些实验结果。

Color image processing using logarithmic operations

In this paper, we present a mathematical model for color image processing. It is a logarithmic one. We consider the cube (-1, 1)3 as the set of values for the color space. We define two operations: addition (+) and real scalar multiplication (×). With these operations the space of colors becomes a real vector space. Then defining the scalar product (.|.) and the norm || · ||, we obtain a (logarithmic) Euclidean space. We show how we can use this model for color image enhancement and we present some experimental results.
