Abstract
In this paper, the oblique projection is revisited by presenting some new findings. It is proved that an orthogonal projector can be expressed as a summation of multiple oblique projectors, each of which has a specific range and null space. Several geometrical illustrations are presented to provide a better understanding of the proposed model. Some applications of the multi-way decomposition of oblique projection are demonstrated.
