Object position tracking is a well-known problem in robotic vision system design. This chapter proposes a new centre-of-mass(COM) object position tracker integrated circuit design using standard low-cost digital CMOS process technology without the need for a floating gate poly2 layer. The proposed COM tracker is designed using an IBM 130-nm CMOS process with a 1V supply voltage and can be used for...
We present the discrete dipole approximation (DDA) simulation of light scattering from bead enhanced grating to determine the relationship between the number of beads forming the grating and diffraction intensities of first and zero orders. The models of grating are prepared by volume slicing and image processing while the spatial locations of the beads are randomly computed using discrete probability...
Nowadays wavelet transform has been one of the most effective transform means in the realm of image processing, especially the biorthogonal 9/7 wavelet filters proposed by Daubechies, which have good performance in image compression. Hence, in this paper an attempt has been made to analyse traditional and adaptive lifting based wavelet techniques for image compression. The original image is transformed...
We present a modified structure of 2-D CDF 9/7 wavelet transforms based on adaptive lifting in image coding. Instead of alternately applying horizontal and vertical lifting, as in present practice, Adaptive lifting performs lifting-based prediction in local windows in the direction of high pixel correlation. Hence, it adapts far better to the image orientation features in local windows. The predicting...
Dissociation between β‐adrenergic behavioral and physiological defensive active coping (AC) responses was associated with cardiometabolic risk in urban but not rural African males. Whether this is partly driven by underlying neuroendocrine dysfunction is not certain. We aimed to assess the association between coping style, urbanization, and neuroendocrine function. Blood pressure (BP) and serum stress...
Temporomandibular joint (TMJ) is a two-sided articulation via which the jaw moves with respect to the skull. As a key component, the articular disc residing in the TMJ plays a critical role in absorbing the shocks to the joint and lubricating the mandibular movement, whose incorporation in FEM study is considered to bring more complicated interpretation than other elastic components in terms of inside...
Wearable assistive devices assist rehabilitation and recuperation; however, their development is impeded by traditional control paradigms. Presented is a novel control structure for a WAD, whose joints are antagonistically actuated by pneumatic McKibben actuators. Here, we discuss the actuators and controller's two sub-sections: the joint torque controller and the differential pressure controller...
Wearable assistive devices (WAD) assist rehabilitation and recuperation. However, WADs' development is impeded by traditional actuators and current control paradigms' lack of compliance and adaptability, in contrast to the mammalian central nervous system. A limb's joint's compliance is a function of muscles' level of activation and passive viscoelastic properties. Increased equal and unequal co-activation...
