Image mosaicing has many applications

such as image based rendering

video retrieval

scene matching

etc. Aiming at images with rotation and scale

a method of image mosaicing based on log polar coordinate mapping is put forward to obtain scene representation of wide view field .In this method

firstly each image is transformed from Cartesian space to log polar coordinate space

which causes scale and rotation in Cartesian space to be manifested translation in log polar coordinate space

and the translation between the pair of input images is calculated

then phase correlation method is used to estimate rotation angle and scale factor between the pair of input images

and then these motion parameters are refined by nonlinear least square iterative optimization algorithm

lastly image blending is imposed to implement image mosaicing. The experiments show that it is an available method of image mosaicing.
