A Background Correction Method for Particle Image under Non-uniform Illumination Conditions

摘要：

The limitation of imaging condition in actual environment often causes the non-uniform background light on the images during the course of capturing. In order to solve the problem, this paper proposed a method based on homomorphic filtering after discussing the characteristic of various common algorithms. It carried out treatment on image frequency region space, weakened low frequency component and strengthened the high frequency component appropriately, so it can reduce the effects of uneven illumination background to what image brings about. The experiment proved tbat the proposed method is better than some traditional methods.
