This process is usually performed with the assistance of a complex edit program. In a quest to obtain seamless results, it is essential to stitch an image with exact overlaps along with exposures that are identical. Once this is achieved, the final outcome would be absolutely flawless. With technology reaching new heights, digital cameras are available today that have the ability to stitch an image internally.
There are three important components associated with the process of image stitching.
While carrying out the process of image stitching, the editor should ensure that there is minimum difference between overlapping pixels. In order to achieve this, it is important to first identify matching features in different images. This can be done with the help of direct alignment methods. Ideally, the expert working on the image should calibrate images so as to obtain better results. Additional efforts should be taken to ensure that matching features are identified between images. There are cases wherein there are minute groups of features that match and hence tools that can identify accurately should be made use of. The comparison is not only accurate, but faster as well. Reputed image stitching services tend to use the most effective tools and hence are able to come up with the best results.
It is essential to minimize the difference between the camera lens combination and ideal lens models including exposure, distortions, and chromatic aberrations and vignetting. This can be achieved with the help of Image calibration. To stitch more than one image, it is important to know the exact positioning of the features involved in an image. Hence, recording and saving the positioning of features in images becomes a vital process. Once the positioning is saved and available, images are placed on the panosphere.
The adjustments that are identified during the calibration stage need to be executed in a near perfect manner….
