Pseudo-color refers to coloring an image by mapping gray scale values to a three dimensional color space. In this paper we used a pseudo-color technique in frequency domain to enhance ultrasound images. We(More)
The paper presents a nonlinear modeling technique for an air vehicle system, called Twin Rotor Multi-input Multi-output System (TRMS) using neural networks and particle swarm optimization (PSO). Since the TRMS permits both 1 and 2 degrees of freedom (DOF) motions, it can be considered as a static test rig for an air vehicle. Modeling of TRMS is perceived as(More)
