Introduction

AMAZE is a Multiresolution Painting and Compositing Utilitiy, based on the idea proposed by Deborah F Berman, et. al. in the paper titled Multiresolution Painting and Compositing. This was done as a part of the Computer Graphics - 2000 course work at
Department of Computer Science and Automation, Indian Institute of Science, Bangalore.

The basic idea here is to decouple the image resolution, from the actual image. The actual image may contain information with different resolution at different regions of the image, and hence the image should not be bound to a particular resolution. The image resolution is needed only for the purpose of viewing the image, and it should be given as an option to the person viewing the image.

The utility uses the quadtrees structure to store the image information. This is suitable for the multiresolution images, because, as the image resolution varies at different regions of the image, the quadtree depth also varies at different places. Hence, we can deviate from the normal approach, used in the traditional imaging utilities, of storing the complete image in its highest resolution.

Also, the system makes use of Haar wavelet decomposition of the image, which is then stored in a sparse quadtree structure. This wavelet representation has several advantages. First, the wavlet representation, itself is concise in that it contains the same number of wavelet coefficients as there are pixels in the original image. Second, this representation supports more efficient compositing than plain image pyramids. Finally, wavelets can also be used to achieve high compression rates on the images.

Screen Snapshots of AMAZE

Here we present few screen snapshots of AMAZE

Flowers flowers everywhere........
This was created by compositing lots of the flower images at varying resolutions, using the different compositing operations of AMAZE.

Sky scrappers in the sea......
See at these two images..

Combining these two images at different resolutions resulted in the following image having skyscrapers on the sea...

Aircraft competeing with stars.......
The combination of the two images again

Black dots illusion........
The original image in rgb format was takig 208 Kb of space
The saved quadtree image took 160 Kb of space, with additional benifits of multiresolution viewing and compositing.

Finally, Wondering how the images are stored in a quadtree?
The following snapshot would give you an idea....
This was generated, by making minor modification in AMAZE.
