In order to reduce the pressure of data storage and transmission on satellite, researchers implemented a method of object region data extraction from remote sensing image in orbit. This method stores and downloads pixels of interesting region through interesting region labeling. But encoding data volume (EDV), hardware scale and real-time property (RTP) are difficult to be balanced. To solve this...
This paper studies influencing factors on the structure of clouds and the availability of satellite remote sensing images on base of that, and puts forward that the cloud area, cloud thickness and cloud fragment are the main factors. Combined with immune coding algorithm, the cloud area can be calculated; with the impact patterns on images by atmospheric scattering, refraction, and so on, a method...
For two-classes image pattern recognition problem about object and background, based on the existing feature selection methods, a novel image feature selection method named immune antibody construction algorithm (IACA) is proposed using immune antibody encoding mechanism. In the case of sample parameter estimation, this method dose not only take into account individual feature's sensitivity to object...
A novel chain code and a new clustering-based algorithm are proposed to detect the curve in the binary image. The novel chain code, which is termed angle chain code (ACC), is more proficient and precise in describing the local-shape of the edge than classic chain codes. Thanks to the ACC and the extraction of geometries, the clustering-based algorithm can detect the mathematic models of contours efficiently...
A novel image interpretation method for cloud detection under complex background was proposed utilizing the texture diversity of clouds and background in satellite remotely sensed images. The affinity formula of the training image's immune primitives was presented by statistical analysis, which bears an analogy with the lowest amino acids combinative energy according to the biological immune antibody...
