Interactive large-scale image editing using operator reduction

Abstract

With advent of advances in digital imaging technology, large-scale high-resolution images become commonplace these days. Automated digital cameras or scientific instruments can produce tens of millions pixel images at interactive rates, and modern photo editing software can stitch such high-resolution images to create much larger-scale panoramic images with minimal user efforts. Those large-scale images convey rich information of objects and scenes by providing both large field-of-view when zoomed out and extremely fine details when zoomed in, which is not available in normal-sized images. In addition, such high-resolution imaging is becoming an important research tool for scientific discoveries.
