Dr Mikolajczyk's research activities are in computer vision and machine learning for visual recognition, retrieval and matching. His particular interests are in invariant feature extraction and visual signal representation which he applied to many computer vision tasks including image and video classification, object recognition and tracking, visual surveillance, large scale image retrieval, wide baseline matching, face recognition, 3D reconstruction, segmentation, etc.
