Research On Mirror Reflection Removal And Image Inpainting Algorithm Of Digital Image

With technology developing and the advent of the internet age,Digital image has become one of the most important information carriers in our lives.However,reflections of windows or glass panes always destroy the photograph that we want to take by camera or phone in life.In order to reduce the interference of reflected light and improve image quality,people have tried various ways to remove reflection from the image,but image processing results of them still exist some defects.Therefore,under this background,this paper studies single image based reflection removal technology and multiple image based reflection removal technology according to the difference of input data of experiment,respectively.In combination with former work,the goal of this paper is to get a faster and better algorithm for reflection removal and reduce the assumption and the human workload during image processing,the use of additional hardware or software equipment at the same time.The main research achievements are shown as the following:1.With the development of GPU parallel technology,this paper puts forward a reflection removal algorithm based on GPU,has sped up reflection removal algorithm by using ghosting cues,and the GPU-based implementation is faster(up to 18 times)than the CPU-based implementation.Besides,an update algorithm is proposed using the image restoration method of non-locally centralized sparse representation in order to achieve the requirements of higher quality of the image effect.2.Based on the relative smoothness of the image gradient,we build our model,put forward a reflection removal by using relative smoothness algorithm.Experimental results show that the algorithm has outstanding detection effect for high light area of image.3.A motion-based reflection removal algorithm is proposed according to the difference of the motion fields for the reflection and background layers.The algorithm has a better output effect compared with the single image based reflection removal algorithm,and obtains a cleaner image.For the digital image,this paper improves the speed of operation under the premise of ensuring the quality of image processing using the GPU parallelization technology,discusses how to improve the effect of mirror reflection removal algorithm and obtain the optimal results,expect to further improve the general applicability of the algorithm.
