The Image Processing Group was founded in 1994 by professor Sven Lončarić. The group conducts research in theory and applications of image processing, pattern recognition and computer vision methods in various areas including biomedical imaging and image analysis, visual inspection, and automotive applications. The main research problems include image feature extraction, image segmentation, image registration, and motion analysis. In the area of biomedical image processing and analysis, we have investigated methods for retinal image analysis, real-time intravascular catheter tracking from X-ray image sequences and 3-D reconstruction of catheter tip, atlas-based image analysis of cardiac ultrasound Doppler images, nuclear medicine image analysis, and CT and MR brain image analysis. For automotive multi-camera systems we developed real-time methods for non-linear and perspective correction of fisheye lenses and image stitching. In biometric security applications we developed methods for personal ID image analysis for quality control of passport photographs. We developed a system for tiled multi-projector visualizations on flat or cylindrical surfaces for large panoramic visualizations and simulation of virtual environments. In the area of industrial visual inspection we have developed methodology and software for automated visual inspection for various industrial manufacturing applications.

IPG has available various research equipment including industrial GigEVision and Firewire digital video cameras and network IP cameras for multi-view scene analysis such as multi-view face recognition for security applications, intelligent surveillance applications, and complex object tracking problems. A high-performance computing cluster is used for research of complex information processing algorithms. IPG also has equipment for realization of virtual reality and augmented reality systems including active and passive 3-D stereo visualization of virtual environments using LCD shutter glasses, and a position tracking device. Computer-controlled multi-source lighting equipment is available for 3-D object analysis.

The group has founded and organized a series of biannual international scientific symposia "Image and Signal Processing and Analysis" and has organized the "2013 IEEE SPS Summer School on Biomedical Image Processing and Analysis", and "2014 Summer School on Image Processing". The group initiated formation of the Center of Excellence for Computer Vision at University of Zagreb, Croatia.
