For over a decade, image mosaicing techniques have been widely used in various applications e.g., generating a wide field-of-view image, 2D optical maps in remote sensing or medical imaging. In general, image mosaicing combines a sequence of images into a single image referred to as a mosaic image. Its process is roughly divided into the iterative image registration and blending. Unfortunately, the computational cost of iterative image registration increases exponentially given a large number of images. As a result, mosaicing for a large scale scene is often prohibitive for real-time applications. In this paper, we introduce an effective visual criterion to reduce the number of image mosaicing iterations while retaining the visual quality of the mosaic. We analyze the change in invariant color histograms of the mosaic image over iterations and use it to determine a termination condition. Based on various experimental evaluations using four different datasets, we significantly improve the computational efficiency of mosaicing algorithm.
