Research Of Removing Methods For The Reticle Interference In Digital Image

As measurement markers and measurement scale tools,reticle has an important role.But if the dividing lines on the reticle remain on the acquired image,the dividing lines on the reticle would had a negative impact. This article discussesd how to remove the dividing lines, providing a theoretical and test data for the removaling of reticle interference.According to different theories, this article proposed reticle interference removaling method based on median filter and reticle interference removaling method based on image inpainting.In the first method, taking into account the characteristic of reticle,this paper presents a new method of removaling dividing lines based on the directional medial giltering with weights.In the second method,we focuse on the the BSCB algorithm, TV algorithms and exemplar-based inpainting methods especially the Criminisi algorithm. This article gives the theoretical and algorithm implementation methods of the three algorithms. Lastly, This paper analysis the defects of the algorithm, through redefining priority, improving the search strategy and adding matching item, the new method improved its accuracy and speed.Experiments show that the method of removaling dividing lines based on the directional medial giltering with weights can removal the retical which with small size.The improved algorithm based on Criminisi algorithm acquires satisfactory effect,at the same time the speed of the algorithm has been greatly improved.
