In this paper, a novel color space transform is presented. It is an adaptive transform based on the application of independent component analysis to the RGB data of an entire color image. The result is a linear and reversible color space transform that provides three new coordinate axes where the projected data is as much as statistically independent as possible, and therefore highly uncorrelated. Compared to many non-linear color space transforms such as the HSV or CIE-Lab, the proposed one has the advantage of being a linear transform from the RGB color space, much like the XYZ or YIQ. However, its adaptiveness has the drawback of needing an estimate of the transform matrix for each image, which is sometimes computationally expensive for larger images due to the common iterative nature of the independent component analysis implementations. Then, an image subsampling method is also proposed to enhance the novel color space transform speed, efficiency and robustness. The new color space is used for a large set of test color images, and it is compared to traditional color space transforms, where we can clearly visualize its vast potential as a promising tool for segmentation purposes for example.
