Research of an Image Mosaic Method for Removing Ghost of Moving Targets

For the problem of moving targets occurring in image sequences will cause ghost phenomenon,propose a new image mosaic method to remove the ghost of moving targets. At first,the algorithm takes motion segmentation to the video images,and uses edge feature points for image matching,then generates a binary template by Markov random field,and eliminates the feature points which exist on the template,thus ensuring the accuracy of image matching. In the blending phase,use active contour model to generate an optimal mosaic line,the resulting mosaic line take full account of the image edge features and gradient information,to ensure that the texture differences of both sides of the fused image smaller. Selecting multi- frame images from successive video for the image mosaic,and the experimental results show that this algorithm has achieved a better image mosaic effect.
