Abstract :
Image processing strongly relies on the quality of the input images, as images of good quality can significantly decrease the development effort for image processing and analysis algorithms. A flexible acquisition system for image enhancement, which is able to operate in real time under changing brightness conditions, is suggested. The system is based on controlling the aperture of the lens, which makes it useable in combination with all types of image sensors. The control scheme is based on an adaptive image quality estimator and can be used for full images and regions of interest within images. We demonstrate the realtime performance of our approach for different static and dynamic in-and outdoor test scenarios with and without region of interest
