With discussion on the sporopollen characteristics,ecologic background,paleoclimate and environmental changes,three kinds of ecologic background,i.

This paper presents an improved background generation algorithm based on sequence image.

Aiming at background generation problem of traffic image object detection,this paper puts forward a method of background generation,defines the transportation sequence picture as three states,classifies the transportation sequence picture by using synergetic method,gives different states of transportation picture different weight,and gets the initialized background by using weighting average.

On the generation background of Derrida s deconstruction theory;
