Abstract The tasks of image reconstruction from measured data and the analysis of the so produced images are more or less strictly separated. One group computes by applying reconstruction algorithms the images, the other starts out of that by operating on these images to enhance the analysis. The aim of the lecture is to provide a tool to combine these two steps; i.e., already in the reconstruction step the future image analysis step is taken into account leading to a new reconstruction kernel. We concentrate on linear methods. As practical example we consider the image reconstruction problem in computerized tomography followed either by an edge detection or by smoothing noisy images with a diffusion process. We calculate new reconstruction kernels and present results both from simulations and from real data.
