A huge amount of memory overhead would be occupied when the high-resolution core images are transferred, disposed and displayed compared to the low-resolution core images. The traditional solutions could not display a high-resolution core image online. A tiled image segmentation method based on tiled pyramid model is proposed to solve the problem. The original high-resolution images are firstly converted to Tagged Image File Format(TIFF) images with multiple resolutions, and then browsed and displayed by block transmission and sub-block loading in client browser.
