Well a very interesting post gives an example for the generation of image mosaics with JavaScript and Ajax. The authors employs a JavaScript binary file reader and uses the raw values from greyscale BMPs to find the mosaic. The approach for mosaic creation is simply yet effective: The overall luminance of an image is taken as “single value descriptor” and single pixels are substituted by very small BMPs.
