Dr. Tardi Tjahjadi has extensive expertise in the areas of multiresolution image processing, image enhancement, object tracking and motion estimation, 3D object/scene reconstruction, gait recognition, activity recognition, facial expression recognition, and expert systems. He has published numerous papers in these areas. He heads the Image Processing and Expert Systems (IPES) Laboratory.

Dr. Tjahjadi has developed several algorithms for: enhancing images; a multiscale step and roof edge detection using cubic B-splines; colour image segmentation; object matching & tracking using constraint cubic B-splines and multiresolution optical flow; recovery of scene structure from an image sequence; multiple-view camera calibration; multiresolution image texture segmentation; octree-based object reconstruction from multiple views; silhouette-based gait and activity recognition, and affective computing, i.e., emotion recognition via facial expressions and EEG signals.

Dr. Tjahjadi has also developed expert systems for X-ray rocking curve analysis, X-ray image topography, image contrast enhancement, and differential diagnosis of obstructive sleep apnoea.

Research interests:
Dr. Tjahjadi's current research interests include affective computing, i.e.,  emotion recognition from facial expressions, EEG signals and body language, gait recognition for human subject identification,  3D scene reconstruction from depth from defocus, video sequences and from multiple views, and image enhancement.

Teaching interests:
ES4E9 Affective Computing
