Abstract:A new face beauty system based on SDM and weighted mean filtering is presented.Firstly,the system uses Supervised Descent Method to realize the key point positioning of the face.Secondly,it uses Interactive Image Warping to realize the local deformation of the face.Thirdly,it uses the surface blur algorithm to adjust the skin texture.Compared with other facial beauty systems,the system can adjust the intensity of retouching to achieve face beautification effects such as face thinning,eye beautification,and speckle reduction.At the same time,the picture after the beautification of this system can still retain the definition and detail feature information of the primitive image.
