In video coding, the sum of squared differences (SSD) is traditionally used for rate-distortion optimization (RDO). However, SSD has been known that has low correlation on subjective quality. In particular, film grain noise (FGN)-synthesized video se

This paper is associated with the two special approaches on face detection. Firstly, we develop a novel face detector for detecting the human faces in a still image by using the unscented Kalman filter (UKF). The first approach or the face detector i

A new approach for image matting is proposed based on the Kalman filter, to extract the matte and original foreground, despite the presence of noise in the observed image. Different filter formulations with a discontinuity-adaptive Markov random fiel

Photographic film contains film-grain noise that translates to multiplicative, non-Gaussian noise in the exposure domain. A method based on the unscented Kalman filter can suppress this noise while simultaneously preserving edge information. � 2008

Image authentication has applications in security systems, photo forensics, and photo journalism. This paper presents an image authentication scheme using added signal-dependent noise. Imperceptible noise is embedded into the image at the time of acq

The distribution and processing of archived film sequences for various purposes often requires “film grain management” to enhance the visual quality or enable better compression results. Film grain management includes (1) the removal or reduction

Part of our cultural heritage includes AV content stored on chemical film that is scanned, archived, processed electronically, and distributed for various purposes. Grain particles in the film lead to visible film grain noise in the viewed and/or sca

We address the problem of inpainting noisy photographs. We present a recursive image recovery scheme based on the unscented Kalman filter (UKF) to simultaneously inpaint identified damaged portions in an image and suppress film-grain noise. Inpaintin
