To avoid the limitation of present QR code algorithms which are only available on the paper presswork, this paper proposed an algorithm based on Pattern Recognition to realize the identification of the QR codes printed on various materials with different models. The QR codes from the sample images were manually marked first, and then the input images were(More)
Microglia activation initiates a neurological deficit cascade that contributes to substantial neuronal damage and impairment following ischemia stroke. Toll-like receptor 4 (TLR4) has been demonstrated to play a critical role in this cascade. In the current study, we tested the hypothesis that hydroxysafflor yellow A (HSYA), an active ingredient extracted(More)
This study aims to demonstrate the feasibility for classifying kiwifruit into shape grades by adding a single camera to current Chinese sorting lines equipped with weight sensors. Image processing methods are employed to calculate fruit length, maximum diameter of the equatorial section, and projected area. A stepwise multiple linear regression method is(More)
Fruit information perception and nondestructive picking method are the key technologies for harvesting robot. In this paper, the kiwifruit automatic identification method and nondestructive picking end-effector were studied. Firstly, a method of obtaining image from the bottom of fruit was proposed based on the clustering characteristics of fruit and the(More)
The purpose of this research is to develop software to optimize the data compression of a PDF417 barcode using VC++6.0. According to the different compression mode and the particularities of Chinese, the relevant approaches which optimize the encoding algorithm of data compression such as spillage and the Chinese characters encoding are proposed, a simple(More)
