This paper presents a Bayesian network model for content-based image retrieval (CBIR). In the explanation and test of this work, only two images features (semantic evidences) are involved: color and shape (from gradients of directions). However, one of the main advantages of the proposed strategy is its easy extension to several evidences. Considering the(More)
This work describes the implementation of impedance control with shape memory alloy (SMA) actuators in a lower limb exoskeleton. Impedance control can be embedded in robotic systems that physically interact with a human user or the environment. In this context, the use of SMA actuators with impedance control to drive the hip joint of a lower limb(More)
