    • PROBLEM TO BE SOLVED: To improve image analysis and tracking of objects in a scene captured by a monitoring camera.SOLUTION: A method (200) and an object analyzer (104) for analyzing objects in images captured by a monitoring camera (100) uses a first and a second sequence of image frames. The first sequence covers a first image area (300) and has a first image resolution, and the second sequence covers a second image area (302) located within the first image area (300) and has a second image resolution higher than the first image resolution. A common set of object masks is provided in which object masks of objects (304) that are identified as being present in both image areas are merged.
