Nowadays, many images of cropland are photographed and transferred by wireless sensors in agricultural automation. But one contradiction is that the recognition needs images with high quality and the transmission needs images with small sizes. So, in this paper, by extracted and analyzedthe loss in the fractal encoding,we use fractal image encoding into the(More)
BACKGROUND AND AIMS Although silicon (Si) has been widely reported to alleviate plant nutrient deficiency, the alleviating effect of Si on potassium (K) deficiency and its underlying mechanism are poorly understood. Here, we examined whether Si-regulated putrescine (Put) metabolisms are involved in Si-alleviated K deficiency. METHODS Sorghum seedlings(More)
Membrane lipid alterations affect Al tolerance in plants, but little is known about the regulation of membrane lipid metabolism in response to Al stress. Transgenic tobacco (Nicotiana tabacum) overexpressing rice monogalactosyldiacylglycerol (MGDG) synthase (OsMGD) gene and wild-type tobacco plants were exposed to AlCl3, and the impact of Al toxicity on(More)
Today, in the multimedia encoding technology, fractal image coding is an effective coding method without resolution. The effectiveness is because of the high compressing ratio of fractal image coding. But the computational complexity of this coding method is so high that it needs long encoding time. In this paper, a novel fast fractal coding method is(More)
