Introduction Photo Mosaic is an exciting art form made from thousands of small pictures, placed in patterns like original mosaics made from colored cells, but each cell is an actual photo. [4] So there are two important parts for photo mosaic. They are the original image and the cell images also called tiles. The Main Image is a single image that will be used to map the cell Images in order to create a photo mosaic. And the Cell Images are the many pictures that make up the photo mosaic. When creating a Photo Mosaic, each cell is analyzed and is optimally placed in patterns. [1] This application is a little program for to create mosaic made with photos. To create such kind of mosaic we need a collection of images that are going to be the tiles of the mosaic and we also need an image to use for the original, as a matrix for the mosaics. The application is composed by 3 main components: the main library which contains all the relevant code, an application to pre-process and store them in the database and
