In this paper the optimum methods of active-surface and level set segmentation was analyzed,then a novel approach to joint space-time was presented,which simplified the problem into an interactive estimation of motion parameters and segmentation surface.The model was formulated and then scattered using Fast Marching Method.Finally,these two-frame and multiple-frame methods were evaluated and compared by examples,the results showed that the later method has higher authenticity.

High-resolution remote sensing technology is applied in the field of military and civilian,image registration technique is high-resolution remote sensing image pre-processing technology.The actual airborne and satellite remote sensing imaging device,because of their own imaging principles and imaging platform jitter,is applied remote sensing image sub-pixel offset error.This article appears remote sensing image analysis of image distortion,and mainly analyses sub-pixel image registration techniques.High precision sub-pixel registration algorithm is discussed,and simulation algorithm,processing and analysis of simulation systematic are studied,finally it is the analysis of the results of the matching algorithm to amend errors,correct algorithm is applied in sub-pixel registration technology research,and the purpose of remote sensing image pre-processing.
