Microarray is a powerful tool for simultaneous study of the behavior of thousands of genes through analysis of produced images. The correct segmentation of each " spot " of the microarray image is a critical step in the analysis of the results of an experiment. In this paper a graph based method is proposed which automatically performs the segmentation.(More)
A recently introduced structure for the capacitive micromachined ultrasonic transducers (CMUTs) has focused on the applications of the asymmetric mode of vibration and has shown promising results in construction of super-resolution ultrasound images. This paper presents the first implementation and experimental results of a transceiver circuit to interface(More)
Motion estimation is a critical part of any video coding scheme. Block matching schemes, though being easy to implement, could produce poor results when multiple moving objects exist in one block. In this paper a new mesh-based algorithm is presented which uses affine transforms. The algorithm searches for codirectionality among pixels of a mesh element.(More)
