Many scintigraphic studies are based on the comparison of two images recorded using different traces. The processing of these Double Tracer Studies (DTS) combines the difficulties of any image comparison and those arising from the fact that the image

A new distribution-free identification criterion based on sign changes in the residuals is presented. The maximization of this non-differentiable criterion is carried out by a global optimization routine using an adaptive random search strategy which

This paper, written from a user stand-point, advocates the Adaptive Random Search strategy as an efficient tool for global optimization. First is presented a brief overview of the various types of methods available in the literature for global optimi

The computer comparison of two images requires a registration step which is usually performed by optimizing a similarity measure with respect to the registration parameters. In this paper a new class of similarity measure is introduced, which is issu

A system is presented for digitization and automated comparison of photographic images of patients obtained at different times using a high-precision video camera. The images can be acquired either directly or from slides. The two images to be compar

New algorithms for automated comparison of scintigraphic images have been developed and are described here. The first step presented here is the registration of the images, performed by optimizing, with respect to the registration parameters (two tra

The detection and visualisation of the changes between two images is the basis or the goal of several imaging techniques. Thus, digitized subtraction angiography consists in visualizing the differences between two images obtained without and with iod

The computer comparison of two images of the same organ requires normalization of the images. We propose an iterative, automated method of normalization that is highly insensitive to structural modifications in the images. The normalization factor is
