Image Mosaics via the Novel Saliency Map

Image mosaics is recently very popular in image processing. The image saliency is used in the whole process of creating an image mosaic with variable size tiles, while a novel energy map is proposed by the improved It´s saliency detection algorithm. The target image is divided into small tiles with variable sizes based on the energy map. Image retrieval is introduced to choose the tile images from a certain database. Considering the specialization of tile image retrieval, we propose luminance maps, color maps and orientation maps. Extensive experiments are conducted to show that the proposed approach creates better mosaics in visual aspect than the conventional methods.
