Image re-ranking, as an effective way to improve the results of web-based image search, has been adopted by current commercial search engines such as Bing and Google. Given a query keyword, a pool of images are first retrieved based on textual information. By asking the user to select a query image from the pool, the remaining images are re-ranked based on their visual similarities with the query...
Wetland ecosystems have strong ability for carbon storage and fixation, and play important roles in the global carbon cycle. The accurate estimation of the leaf chlorophyll content is a significant foundation for researching wetland ecosystem cycle models. In this paper, the inversion of the leaf chlorophyll content was based on PROSPECT model from the physical mechanism angle. Leaf spectrum was simulated...
This study selected aquatic vegetation in BaiYangDian Wetland Nature Reserve in Hebei Province. Measuring the spectral reflectance of typical aquatic vegetation included stonewort, reed, lotus and typha, involved high-resolution GeoEye-1(GE) remote sensing image, based on spectral reflectance of different species simulating bands of GE, calculated the simulated bands, educed better bands or band combinations...
