Overview of Super-resolution Techniques

A robust control scheme for a 2PUS+RR parallel robot for ankle rehabilitation

“…For the interval t = [4.25 s, 7.25 s], this movement starts at = 0.523599 rad and ends at = 0 rad. In the bibliography consulted [11, 12, 17], in order to begin to see a response from the control implemented in the ankle rehabilitators, an approximate time period of between 0 and 20 s was used. In Fig.…”

“…An example of this is provided by the research of Azcaray et al [8] and Guzmán et al [9] which used PID (Proportional integral derivative) control techniques in ankle rehabilitators. Other authors state that there are also combinations of this technique, such as the FOPID (fractional-order proportional integral derivative) by Sinasi Ayas et al [10], impedance control by Magadán et al [11] as well as sliding modes by Chen et al [12]. In another work, Li et al [13] described an ankle robot based on a parallel mechanism actuated using four pneumatic muscle actuators to provide three rotational degrees of freedom to the ankle joint.…”

Improving the iterative back projection estimation through Lorentzian sharp infinite symmetrical filter

“…Thus, all parameters involved above description to an analytical model show as in (1): The parameter matrix 𝐷 𝐾 represents the decimation factor, which this ratio factor represents an enlargement factor size between the ideal reference image and the kth measurement image. This ratio is obtained from the division between the size of a pixel in the measured image 𝑀 𝑘 2 and the reference image 𝐿 2 . If choosing a very high ratio factor of the decimation and will cause the ill-posed problem and the image suffers from lost a lot of information.…”

“…The SR reconstruction is referring to the recovery techniques in image processing that obtains a high resolution (HR) image from observed single or multiple LR images. To produce the HR image, the researcher has manipulated the mathematical expression of the imaging model which describes the sensor characteristics, such as motion blur, decimation, and shifted translation in the camera PSF [1], [2], [10], [11], [15].…”
