在多角度图像拼接中利用查找表对图像进行分段线性颜色校正

olor correction, which is widely used in image mosaic, is to transfer the color of a source image to that of a target image. Images are acquired by different sensors usually have different colors with different parameters such as exposure time. Thus, in order to reduce differences between the source image and the target image to have a further image process, we proposed a look-up table method to calculate the color mapping and evaluate this method with color similarity and structure similarity. Experimental results show that the proposed look-up table method could reduce the color difference between two images effectively and have a better performance compared with other method in color similarity.
