PROCESSING TECHNIQUES AND EQUIPMENT FOR SUPERIMPOSING IMAGES FOR PROJECTION |
摘要 |
Addressed herein are techniques and equipment for pre-processing digital images to be superimposed for display. Filtering, re-sampling, and decimation are variously used to process images and sub-images to produce to-be-superimposed images. One of the described techniques is designed primarily (although not necessarily exclusively) for computational efficiency, while the other sacrifices some computational efficiency for higher quality of output images.
