Spatial video watermarking algorithm based on<br /> human visual system and DCT<br />
We propose a novel video watermark algorithm based on the visual characteristics of block DCT direct current (DC) coefficient which considers the JND model in human visual system (HVS). In order to meet the invisibility...
Study on the surface morphology of sulfide copper ore<br /> in bioleaching experiment<br />
The bioleaching behavior of low-grade copper sulphides under the condition of preferential solution flow was investigated through experiments. The experiment of bioleaching of low-grade copper sulphides under the conditi...
Effect of organic additives on porous silicon nitride ceramics prepared by extrusion method
Porous silicon nitride ceramics with excellent properties were prepared by adding different organic additives into the initial silicon nitride powder by extrusion method. Effect of organic additives on microstructure and...
Controlling factors of treatment of high-strength ammonia wastewater by immobilized microorganism
