Extraction of loess shoulder-line based on object-based image analysis
Based on the morphological characteristics of loess hilly and gully areas, a simple and effective method for extracting loess shoulder-lines based on object-based image analysis is proposed. A case study is conducted in the northern Shaanxi Loess Plateau of China and the digital elevation model with a grid size of 5 m is applied as original data in this research. In order to get clear edge of D...
متن کاملA New Extraction Method of Loess Shoulder-Line Based on Marr-Hildreth Operator and Terrain Mask
Loess shoulder-lines are significant structural lines which divide the complicated loess landform into loess interfluves and gully-slope lands. Existing extraction algorithms for shoulder-lines mainly are based on local maximum of terrain features. These algorithms are sensitive to noise for complicated loess surface and the extraction parameters are difficult to be determined, making the extra...
متن کاملConditional Random Fields for Airborne Lidar Point Cloud Classification in Urban Area
Over the past decades, urban growth has been known as a worldwide phenomenon that includes widening process and expanding pattern. While the cities are changing rapidly, their quantitative analysis as well as decision making in urban planning can benefit from two-dimensional (2D) and three-dimensional (3D) digital models. The recent developments in imaging and non-imaging sensor technologies, s...
متن کاملSimultaneous Determination of Carbazoles in Water Samples by Cloud Point Extraction Coupled to HPLC
Cloud point extraction (CPE) as a rapid, simple and efficient method coupled with high performance liquid chromatography (HPLC) was used for sample preparation and subsequent determination of carbazole, trinitrocarbazole (TrNC) and tetra nitro carbazole (TNC) in water samples. Some effective parameters on extraction, such as volume of Triton X-100, extraction time, extraction temperature, ionic...
متن کاملSelective Cloud Point Extraction for the Spectrophotometric Determination of Cetylpyridinium Chloride in Pharmaceutical Formulations
In this work, we developed a simple and selective method for separation and spectrophotometric determination of trace amounts of cetylpyridinium chloride (CPC) in pharmaceutical products using cloud point extraction (CPE) technique. The method is based on cloud point extraction of the CPC in alkali conditions using of nonionic surfactant Triton X-114. Under selected conditions, the calibration ...
