The aim of our robust technique using watermarking is to reconstruct watermark from geometric attacks. Various geometric transformations, such as rotation, scaling, cropping, shear, translation, resize, scattering, bending, and so on, provides the displacement of some of its picture elements. The existing watermarking algorithms countermeasures the attacks related to pixel positions. In our pap...

This paper describes a high capacity blind video watermarking system invariant to geometrical attacks such as shift, rotation, scaling and cropping. A spatial domain reference watermark is used to obtain invariance to geometric attacks by employing image registration techniques to determine and invert the attacks. A second, high capacity watermark, which carries the data payload, is embedded in...

This research was conducted in six typical villages of Northern Bangladesh. A sample of 170 farmers was selected. Research indicates that the farmers practising agroforestry own small farms and the income of agroforestry helps them to reduce their poverty, maintain their socio-economic needs and sustain their livelihoods. Agroforestry is not a new concept in the study area. The people have been...

Cover crop treatments and nitrogen (N) fertilization rates were investigated for their impact on sorghum grain quality attributes. Sorghum was planted in field plots treated with differing cover cropping systems and fertilization rates. The size (weight and diameter) and hardness of the kernels were influenced by both the cover crop and N rates. The protein content increased as the N rate incre...

Understanding and interpreting the temporal variations of the vegetation growth can provide valuable information on its dynamics and in case of crops provide an estimate of the phenological milestones that can help describe the crop. The focus of this work is to use the phenological parameters derived from MODIS EVI time series composite data to map the variability in cropping practices. These ...

Farmers in many regions of the world grow a horticultural or grain crop between sugarcane (a complex hybrid of Saccharum spp.) cycles. This additional crop often requires higher amounts of P or K fertilizers than does sugarcane. Some sugarcane growers in Florida precede 2to 5-year cycles of sugarcane with one crop of spring-harvested sweet corn (Zea mays L.). A disadvantage perceived with this ...

The patterns of different cropping systems are highly variable—as diverse as are the crops themselves and the climates, habitats, levels of mechanization, and human customs under which crop production is undertaken. Depending on the part of the world, certain considerations will weigh more heavily than others. In one place primitive methods are appropriate, in another the system is highly mecha...
