Tools Properties of vision (eye optics, retinal processing) Perspective corrections Image and video interpolation (and compression) Genetic programming Machine learning High-order spectra Image tampering: non-uniformity of the sensor; JPEG statistics Multiscale image representations (for robotic painting) Invisible watermarking Edge-preserving noise removal Skeletonization, 2-D and 3-D Morphological filters Image and Video Processing @ DIA -- 6 June 2013
Competences When final user is human: perceived quality -- Optical effects of misplaced lenses (intraocular lenses), mechanical eye model Qualitymetrics? exploit saliency of image parts to improve correspondence between MOS and quality metrics; use hdrvdp model histogram distance using earth mover distance for image retrieval -- Document analysis for automated acquisition of paper dox OCR, also handwritten, char. separation; SVM -- 3D medical image data: CT reconstruction algos as a function of no. of projections use phase image micro-CT data, analysis of the porous phase -- Video transmission H264 scalable analysis of distortion due to missing packets Image and Video Processing @ DIA -- 6 June 2013
