In the field of seismic interpretation, univariate databased maps are commonly used by interpreters, especially for fault detection. In these maps, contrast between target regions and the background is one of the main factors that affect the accuracy of the interpretation. Since univariate data-based maps are not capable of providing a high contrast representation, to overcome this issue, we turn these univariate data-based maps into multivariate data-based representations using color blending. We blend neighboring time sections, frames that are viewed in the time direction of migrated seismic volumes, as if they corresponded to the red, green, and blue channels of a color image. Furthermore, we apply color transformations to extract more reliable structural information. Experimental results show that the proposed method improves the accuracy of fault detection by limiting the average distance between detected fault lines and the ground truth into one pixel.
