This study introduces a novel visual servo controller that is designed to control the pose of the camera to keep multiple objects in the field of view (FOV) of a mobile camera. In contrast with other visual servo methods, the control objective is not formulated in terms of a goal pose or a goal image. Rather, a set of underdetermined task functions are(More)
The main goal of any electrocardiogram (ECG) compression algorithm is to reduce the bit rate while keeping the signal distortion at a clinically acceptable level. Percentage root mean square difference (PRD), the commonly used figure of merit, does not directly reveal whether the clinically significant ECG waveform information is preserved or not. We(More)
In this demo, we present a novel method to estimate joint angles and distance traveled by a human while walking. Understanding the kinematics of the human leg gives the velocities associated with forward human motion. Gyroscopes and accelerometers placed at two limbs provide the required measurement inputs. The inputs are used to estimate the desired state(More)
Flow around a cavity is characterized by a self-sustained mechanism in which the shear layer impinges on the downstream edge of the cavity resulting in a feedback mechanism. Direct Numerical Simulations of the flow at low Reynolds number has been carried out to get pressure and velocity fluctuations, for the case of un-actuated and multi frequency(More)
This paper presents a visual servo controller designed to keep multiple moving objects in the field of view of a wheeled mobile robot. A set of task-functions are presented based on the distribution of targets in the image. The task functions are are regulated through the mobile robot’s velocity inputs to deter targets from leaving the field of view.(More)
