According to the amino acid sequence of monellin, a single chain 294bp monellin gene was synthesized and inserted into vector pET-22b to yield the recombinant secretion plasmid pETMO. The single-chain monellin gene was designed based on the biased codons of E. coli so that its expression would be then optimized. Under the expressing conditions, monellin was(More)
In this paper,a support vector regression neural network (SVR-NN) approach is presented to assessment the visual quality of JPEG-coded images without reference image.The key features of human visual system (HVS) such as edge amplitude and length, background activity and luminance are extracted from sample images as input vectors. SVR-NN was used to search(More)
