介绍Topographic ICA原理 In ordinary independent component analysis, the components are assumed to be completely independent, and they do not necessarily have any meaningful order relationships. In practice, however, the estimated “independent” component
ArcGIS中读取LAS数据扩展功能 The LIDAR Analyst extension for ArcGIS is a necessary tool for anyone who has LIDAR data. LIDAR Analyst completely automates the extraction of 3D terrain surfaces, buildings, trees, and forest areas from LIDAR. Comprehensive testi
This volume discusses the basic geometric contents of an image and presents a tree data structure to handle those contents efficiently. The nodes of the tree are derived from connected components of level sets of the intensity, while the edges repre

bitmapBit Map is an offline map viewer for your own topographic or specialised maps in a variety of image formats including, PNG, JPEG, OZF2 / OZFX3 (non-RC4). Store multiple maps on your iPhone or iPad, and switch between them. With Bit Map, you ca
DEM-based Watershed Topographic Attributes Extraction and Analysis，原立峰，Zhang Youshui，n this paper we took Yan’er Gully watershed for an analysis instance, using ArcGIS software as a digital terrain analysis tool for studying topographic attributes ex
Confocal Raman microscopy is currently used for label-free optical sensing and imaging within the biological, engineering, and physical sciences as well as in industry. However, currently these methods have limitations, including their low spatial re
A simple biologically inspired feature extraction algorithm is proposed for object recognition. First, a set of statistical topographic filters modelling the properties of complex cells in a primary visual cortex (V1) are learned based on enhanced in
In this article, we reported near-field research on azobenzene polymer liquid crystal films using scanning near-field optical microscopy (SNOM). Optical writing and subsequently topographic reading of the patterns with subwavelength resolution were c
Digitized topographic maps normally have to go through the geometric calibration before practical utilization. Nowadays, the reference points for the calibration are still manually assigned. Corner points (graticule intersections) in a map are usuall
Graticule intersections in topographic maps are usually considered to be suitable candidates for reference points in geometric calibration because the corresponding geographical information can be directly retrieved from the maps or derived from shee
