The pressure delivered the wafer is an element that plays an important role for its local and global planarization in a chemical mechanical polishing process. The non-uniform pressure distribution of the wafer edge especially produces productivity and economic loss in semiconductor device production, and the non-uniform pressure distribution is largely dependent on the pressure change of the retainer...
We propose a new T2 mapping method to improve the CS reconstruction based on the theory of structured sparse representation. The proposed method learns the PCA sub-dictionaries for adaptive sparse representation and suppresses the sparse coding noise to obtain good reconstructions. Experimental results demonstrate that the proposed method capable of delivering state-of-the-art performance at CS reconstruction...
In order to reduce huge computational burden and to improve poor matching performance for existing color SIFT descriptors, we propose a novel color SIFT descriptor via color quantization (CQ). Firstly we quantize the three components of the HSV space and define a one-dimension color vector with a rigorous constraint. Then we introduce the vector to the standard SIFT descriptor and propose the novel...
We propose a novel image interpolation scheme based on prescribed tangent of cubic B-spline curve. Firstly a cubic B-spline interpolation curve is constructed by discrete pixels. Then a straight line is constructed by joining two points on the B-spline curve with respect to two neighboring pixels. The value of the interpolation point between the two points is determined based on the tangent of the...
The reliable and accurate identification of cancer categories is crucial to a successful diagnosis and a proper treatment of the disease. In most existing work, samples of gene expression data are treated as one-dimensional signals, and are analyzed by means of some statistical signal processing techniques or intelligent computation algorithms. In this paper, from an image-processing viewpoint, a...
The important indication of a healthy river are good water quality, smooth channel for water and sediment and the stable eco-system. The attention is paid to the relation between a healthy river and large woody debris(LWD), the contribution of LWD to the healthy river is summarised. The monitoring method of LWD is introduced briefly, and the future research direction and main focus is given at last.
To evaluate the ambient air quality status of the Fuxin city in Aug-Nov, 2011, we established fuzzy comprehensive evaluation mathematical model and membership function using lower semi-trapezoid distribution through the distribution of data collection and selecting the main factor affecting air quality, and have the result that urban monthly average air quality has declined with the temperature during...
