To overcome this problem, a novel fusion algorithm is proposed, which is based on a new image region focus measure, Relative Activity Level (RAL), presented in this paper.

The simulation results showed that under the same coke level, the activity of the coked catalyst depended on the location of the coked sites and the relative coke growth rate.

Sequences tend to show cyclicity of changes in relative sea level and widespread unconformities, processes of sedimentation and sources of sediments, climate and tectonic activity over time.
