An Efficient Algorithm for Earth Surface Interpretation from Satellite Imagery
Many image segmentation algorithms are available but most of them are not fit for interpretation of satellite images. Mean-shift algorithm has been used in many recent researches as a promising image segmentation technique, which has the speed at O(kn2) where n is the number of data points and k is the number of average iteration steps for each data point. This method computes using a brute-for...
متن کاملAutomatic Discovery of Classification and Estimation Algorithms for Earth-Observation Satellite Imagery
Under NASA’s new Earth Observing System (EOS), satellite imagery is expected to arrive back on Earth at rates of gigabytes/day. Techniques for the extraction of useful information from such massive data streams must be efficient and scalable in order to survive in petabyte archive situations, and they must overcome the opacity inherent in the data by classifying or estimating pixels according t...
متن کاملAutomatic Construction of the Motion Database which Allows to Search Contents by a Motion Name
In order to reuse the human motion data recorded by the motion capture, we have proposed a motion database construction method named BUYOFU. In this method, captured motion data are divided into a basic motion which is easy to reuse, and the word explaining the motion is used as a search key. Since we have been performing these processes manually at present, if the amount of basic motion data i...
متن کاملMonte Carlo Based Non-Linear Mixture Model of Earth Observation Satellite Imagery Pixel Data
Monte Carlo based non-linear mixel (mixed pixel) model of visible to near infrared radiometer of earth observation satellite imagery is proposed. Through comparative studies with actual real earth observation satellite imagery data between conventional linear mixel model and the proposed non-linear mixel model, it is found that the proposed mixel model represents the pixels in concern much prec...
متن کاملSatellite earth observation in operational oceanography
The role and contribution of satellite data in operational oceanography is reviewed, with emphasis on northern European seas. The possibility to observe various ocean parameters and processes by existing satellite sensors, such as optical instruments, infrared radiometers, passive Ž . microwave radiometers, and active microwave systems altimeter, scatterometer, SAR is discussed. The basic param...
