In order to solve the problem of time-consuming dictionary training process, we propose an image super-resolution reconstruction approach based on fusion of K-SVD algorithm and semi-coupled dictionary learning framework. In this paper, we use K-SVD algorithm to training the dictionary pair in the semi-coupled dictionary learning model. In comparison with the existing methods, experiment results on...
Ship detection using high resolution remote sensing images is a hot research topic in both military and civilian applications. In this paper, a new method for detection of ships docked in a harbor was proposed, in which, Harris corner detector combined with local salient region analysis were used to extract the obvious sharp-angled feature related to the fore part of a ship in satellite images. This...
To acquire the planted acreage of major grain crops and their spatial distribution in an timely, accurate, quantitative and periodic way is of significance for making a socio-economic development plans at various levels of government, and improving the operational management for relevant enterprises and farmers. The National Bureau of statistics of China (NBS) aims to take the fully advantages of...
Modern semiconductor fabrication defect inspection technologies always pursue high defect capture rate, low false defect rate and low cost. These three factors are constrained by systematic resolution and throughput. Resolution is proportional to defect capture rate and inspection platform cost, inverse proportional to false defect rate. Throughput is the fundamental limiting factor for inspection...
The nighttime lights collected by the U.S. Air Force Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) have a number of favorable characteristics for depicting the spatial patterns of Constructed surfaces on large scale. This paper presents a quantitative analysis on the brightness of nighttime lights and territorial development intensity (TDI) from pixel-scale using...
Based on the properties of integer wavelet transform and multiresolution analysis and combined with human visual specialties, an improved region of interest (ROI) progressive image transmission algorithm is proposed. With no impact on the subjective quality of ROI image, in the first instance, the coefficients in the ROI and the important wavelet coefficients for human vision are transmitted. Moreover,...
