This project is about creating a way to display images in a memory efficient manner. This is done using a quadtree to allow the tiling of an image which then downsamples regions using an interpolation algorithm based on the screen’s resolution. This then involves recycling any non-visible tiles that are thereby freed from memory.
The second phase of this project involves pre-processing images to further help with reducing the memory costs of displaying an image. A colour decomposition algorithm is used to identify regions of an image that contain perceptually similar colours using the CIELAB colour space with the most accurate colour difference formula, CIEDE2000. This is then used to allow regions to be represented without needing decoding any pixel data.
