This paper presents several extensions of the basic CPA algorithm. First we compare CPA to standard corner detection algorithms and then turn to the question of selecting control points with adequate dispersion since this is crucial for accurate registration. Two selection methods are proposed. The first consists of clustering the control points via the Lloyd algorithm followed by selecting the...

In Blind Source Separation (BSS) processing, taking advantage of scaling factor indetermination and based on the floatingpoint representation, we propose a scaling technique applied to the separation matrix, to avoid the saturation or the weakness in the recovered source signals. This technique performs an Automatic Gain Control (AGC) in an on-line BSS environment. We demonstrate the effectiven...

Abstract. Highly accurate geometric correction is necessary for high-resolution data. Then, it is important to acquire the high accuracy Ground Control Point (GCP) and corresponded Image Control Points (ICPs) for geometric correction. The objective of this study is evaluation of GCP type for high-resolution satellite image. In this study, following two types of GCP was selected: 1)Polygon in fi...

I N STATISTICAL process control (SPC), one major concern is whether there has been a change of the distribution from the target in the process. To answer this question, we have to distinguish the variation due to real change of distribution (assignable causes) from that due to random error (chance causes). Many kinds of control charts serve this purpose. When there is no change and the process ...

We consider the problem of energy-mass transfer from scattering to bound states for a one body quantum system uder the action of a time dependent point interaction. Under suitable assumptions on the initial state of the particle, we prove a result of local controllability of this process
