Super-resolution techniques reconstructing a higher resolution image from one or multiple low-resolution images are helpful to visual recognition under the scenarios of insufficient acquisition resolution. Due to the limited wireless network transmission bandwidth or mobile device processing capacity, image resolution in mobile phones and other mobile devices is not as high as expected, which restricts...
This article discusses real estate apportionment and automatic calculation model, and achieves automatic calculation of apportionment area, which belongs to real estate thematic map based on Auto CAD secondary development. It also provides a useful approach to generate real estate thematic map automatically, shows a series of software operating procedures, and demonstrates an example of the combination...
The tendency from the "Digital Scenic" to "Smart Scenic" is still a new challenge and opportunity for the sustainable development of scenic area. Through many deeply studies by related scholars, the grid technology is presented to participate in the smart scenic construction. This paper introduces theoretical foundation and practical applications of grid management and service...
The demands of surveying and mapping products in the management of digital city is increasingly high, the traditional 4D products cannot comfort the demands. With the properties of real-time, integrity, readable, measurable and can be tapped, the 5th surveying and mapping product, can provide information, which is more intuitive and effective compared with the traditional 4D products. Several flaws...
As a specific application of close-range photogrammetry, digital measurable images, combining with the business data in specific field, can provide users a visible, elaborate, high-efficiency system. In this paper, concept, theory and production process of digital measurable image will be presented in detail. On that basis, facade measurement service based on digital measurable images is put forward...
Remote sensing study focuses on not only information of image its own, but also geographic analysis based on these information. Unlike normal image, remote sensing image holds several special characteristics, which make impossible to create hierarchical semantic of remote sensing image only applying classic achievements on image hierarchical semantic. In this paper, we firstly indicate two characteristics...
Considering the inter-scale dependency between the coefficients, a novel progressive rotation-invariant texture retrieval means based on inter-scale dependency is proposed in this paper. Firstly, Logpolar transform and Non-Subsampled Contourlet Transform (NSCT) are combined to get rotation-invariant multi-scale and multi-direction coefficients, then Generalized Gaussian Distribution (GGD) model is...
