Efficient Zooming Using Multiscale Pyramids

Panning across and zooming into a large image requires the import and resizing of large amounts of data. ImagePyramid resolves this issue by readily providing an appropriate scale of an image.

Generate the lowpass image pyramid of a 34-megapixel image.

Resizing the image to an appropriate viewing size takes almost a second.

Obtaining the resized image from the image pyramid is about 100 times faster.

Image pyramids ensure smooth zooming for large images.
