Image Magnification Based On Partial Differential Equation

With the development of science and technology, Image in the process of under-standing the world are playing a more and more important role。However, due to technical problems and imaging equipment itself filming the environmental impact, We need to do image amplifier processing.based on this, This paper first introduces some traditional amplification technol-ogy, And analyzes its characteristics, points out its advantages and disadvantages.Then introduced the image magnification model based on partial differential equation.And dis-cusses its rationality and amplification superiority. According to the image,We put the im-age into image without noise and noise image.According to the former,We introduce heat conduction equation model.We put the image sampling grayscale value as temperature and put the image magnification process as heat conduction;to the latter, based on TV model and BSBC model,We analyzed the advantages and disadvantages of both models,We presented a hybrid model,P—harmonic model.
