Synthetic face generation under various operational conditions in video surveillance [PDF]

open access: yes2015 IEEE International Conference on Image Processing (ICIP), 2015
In still-to-video face recognition (FR), the faces captured with surveillance cameras are matched against reference stills of target individuals enrolled to the system. FR is a challenging problem in video surveillance due to uncontrolled capture conditions (variations in pose, expression, illumination, blur, scale, etc.), and the limited number of ...
