Abstract:
Until now, there has been no objective measure for the quality of mosaic images or mosaicking algorithms. To mend this shortcoming, a new method is proposed. In this new approach, the algorithm that is to be tested, acquires a set of synthetically created test images for constructing a mosaic. The synthetic images are created from a reference image that is also used as a basis in the evaluation of the image mosaic. To simulate the effects of actual photography, various camera-related distortions along with perspective warps, are applied to the computer-generated synthetic images. The proposed approach can be used to test all kinds of computer-based stitching algorithms and presents the computed mosaic quality as a single number.
