THE NEW ORTHORECTIFICATION STRATEGY AS A WAY FOR VISUAL QUALITY IMPROVEMENT

摘要

In the paper a new orthorectification strategy of aerial images is presented. The strategy is focused on improvement of visual quality of orthoimage. The idea of proposed strategy relies on extraction of edges from the image and next special resampling is taken. The critical issue for edge detection is that the images usually includes some noise. The de-noising of an image has many solutions but none of them is perfect. Therefore in the paper the usefulness of wavelet transformation for image de-noising is tested. The proposed orthorectification strategy gives a better image then the image from typical orthorectification. The visual quality of edges in orthoimage is comparable to the original image.
