High-quality image denoising is required for many image processing applications. Our work concentrates on portraying a fast noise process method using PCA referring to weaked textured image patches, with patches generated from the noisy image corrupted by zero-mean Gaussian noise. The main contribution lies in the selection of specified blocks. We adopt a new measurement according to the gradients...
10 risk factors are obtained from the view of energy risk management. The weight of each risk factor is decided by the sequence of PCA-LZNMAP model. Risk coordinate diagram, which intuitively reflects the attention degree of the energy risk factors and the measures which should be taken, was drawn based on these weights. At the same time, it is concluded that the evaluation value of energy risk is...
