Colour is an important clue in many applications in machine vision and image processing. Despite of this, the drawback of colour is its dependence upon illumination changes. Colour constancy aims to provide colour appearance of objects with stability. This paper presents a simple and robust colour constancy algorithm based on a coefficient transformation of the colour coordinates of pixels which goal is to reduce the distance between histograms of two images of similar scenes under different illuminations. Our main contribution is that our algorithm only make use of raw image data contrary to most usual colour constancy algorithms. We show that our approach is able to cope with colour change since it substantially reduces the distance between colour histograms.

This paper presents a study of the behavior of piezoelectric micro robot to three degrees of freedom (longitudinal movement. transversal movement and rotation) foreseen to work on flat surfaces. Its main merits are its ability to perform micro-scale displacements and to support heavy pre-loads. An adequate interface is developed, allowing the control of the system. Even, a phase sensitive vision method is developed to sense the position and the heading angle with an accuracy better than 0.2 pixel i.e. 12 mum with an observed field of about 4 x 3 cm(2). A personnel computer controls the whole system.
