We report a self-healable soft body-integrated ionotronic skin (i-skin) for gesture recognition. The device is made of naturally extracted silk fibroin proteins in the format of hydrogel and functionalized by adding calcium ions and glycerin for high stretchability and conductivity. The silk-Ca2+-glycerin network has high stretchability (up to 600%) and low Young's modulus (0.2-0.3MPa) for conform...Show More
We report a facile patterning technique for precise controlling the degradation of silk protein based optical micro devices by rapid thermal nanoimprinting for transient applications. The solubility of silk films strongly depends on the crystalline conformation of the silk proteins, which can be well tuned by the spatial and temporal modification during thermal treatment. Compared with the previou...Show More
Here we report nanolithography of silk proteins using ultrafast terahertz (THz) pulse with a center wavelength of ~300 μm. This is achieved by metamaterial enhanced local high-field THz field. The THz electric field (E-field) is localized inside the capacitive gaps of the gold split ring resonator (SRR) and enhanced by more than two orders of magnitude [1]. By adjusting the strength of the inciden...Show More
In order to recognizing the feature of abnormality in advance and fix the possible dirty data simultaneously, this article proposed a method to construct a proper mode for a production process producing specific product, a method to estimate the stability of a linear process and a group of data cleaning rule. Both the data processing procedure and algorithm are given detailedly with some samples a...Show More
Target tracking has always been a hot research topic in the field of computer vision. Tracking-Learning-Detection (TLD) is a new algorithm for online learning tracking proposed by Zdenek Kalal. In the algorithm, the computation consuming of detection module is relatively large. To solve this problem and improve the algorithm, we proposed an online learning method to adaptively update the threshold...Show More
Nowadays motion detection in video sequences is the basis for the high-level analytics and applications. After ViBe is proposed, the current mainstream detection algorithm is based on pixel level to construct the background model for the foreground / background segmentation. Influenced by this kind of algorithm, this paper proposes a spatiotemporal-based algorithm to construct an approximate preci...Show More
Visual target tracking is one of fundamental research of computer vision field and play an important role in the surveillance application, but it is also one of the difficulties due to the instability of the tracking scene. In this paper, we analyze the major drawbacks of the original Kernelized Correlation Filter (KCF) tracker which causes tracking failure when target experience complicated scena...Show More
