Abstract
This paper points out the importance of directional propagation with an expression of directional elements at each pixel of a binary image, as an extension of local parallel operations. This paper also proposes “a twisting operation” for an 8‐neighbor operation with an arbitrary direction and an arbitrary directional accuracy. By using this operation and the concept of vibrating operations, such as erosion‐dilatation or dilatation‐erosion, directional local parallel operations are defined to extract linear features. The effectiveness of the ideas is confirmed experimentally.
