The proposed approach exploits spectral properties in conjunction with spatial properties, both of which actually provide complementary information to each other. First, high resolution pan-sharpened color image is obtained via the process of merging high resolution panchromatic and low resolution multispectral imagery yielding a color image at the resolution of panchromatic band. Natural and man-made regions are classified by using Normalized Difference Vegetation Index (NDVI). Then shadow is detected by using chromaticity to intensity ratio in YIQ color space. After the classification of the vegetation and the shadow areas, the rest of the image consists of man-made areas only. Then, the manmade areas are partitioned by mean shift segmentation. However, some resulting segments are irrelevant to buildings in shape. These artifacts are eliminated in two steps: First, each segment is thinned using morphological operations and the length of it is compared to a threshold which is specified according to the empirical length of buildings. As a result, long segments which most probably represent roads are masked out. Second, the erroneous thin artifacts are removed via principle component analysis (PCA). In parallel to PCA, small artifacts are wiped out based on morphological processes also. The resultant manmade mask image is overlaid on the ground truth image, where the buildings are manually labeled, for the assessment of the methodology. The proposed methodology is applied to various Quickbird images. The experiments show that the methodology performs well to extract buildings in complex environments.","PeriodicalId":412236,"journal":{"name":"2009 4th International Conference on Recent Advances in Space Technologies","volume":"5 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130232951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It drives materials recycle loop by biological and ecological functions and creates pleasant life environment on a distant planet. Choice of space diet is one of primary decision required for designing space agriculture. We shall consider diverse food culture as well. We propose cassava, Manihot esculentaand, for one major composition of space food materials. Cassava is a major crop in Africa. It can grow under severe environment. Once farming condition is optimized, the crop yield efficiency is the best among rice, wheat, potato, and sweet potato, in terms of required area to harvest biomass energy from limited area of planting. Propagation made by stem cutting is another advantage of cassava in space agriculture avoiding entomophilous or anemophilous process to pollinate. Cassava for space agriculture would be a good example of promoting mission planning under cooperation between advanced manned space nations and less-space faring countries. It might enforce robustness of the life support capability based on the diversity of agricultural system. More importantly, dream of flying space could be shared by people, regardless of their present commitment to space.","PeriodicalId":412236,"journal":{"name":"2009 4th International Conference on Recent Advances in Space Technologies","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132451257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since materials recycle is driven by limited resources available on extraterrestrial bodies, it can be an extreme model of terrestrial agriculture facing the growth limit at yet increasing population. Choice of food materials to meet nutritional requirements and foods cultural acceptability for space agriculture is the basis of its design. From Asian background, we selected rice, soybean, sweet potato, and green-yellow vegetables. In order to supplement fatty acids and certain vitamins, animal origin foods are required in diet. Among many candidate animals to breed, insects are of great interest since they have a number of advantages over mammals. We propose several insect species, such as the silkworm (Bombyx mori), the drugstore beetle (Stegobium paniceum), and the termite, (Macrotermes subhyalinus). These insects do not compete with crop production, but convert inedible biomass or waste into an edible form. Tri-culture of rice, water fern (Azolla), and loach fish (Misgurnus anguillicaudatus) in rice paddies is another proposal for space, and sustainable agriculture on Earth. In addition, we discuss symbiosis and biological interaction, allelopathy.","PeriodicalId":412236,"journal":{"name":"2009 4th International Conference on Recent Advances in Space Technologies","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114653001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents an approach for building detection in high resolution remotely sensed images incorporating structural information of spatial data into spectral information. The proposed approach moves along eliminating irrelevant areas in a hierarchical manner. As a first step, pan-sharpened image is obtained from multi-spectral and panchromatic bands of Quickbird image. Vegetation and shadow regions are masked out by using Normalized Difference Vegetation Index (NDVI) and ratio of hue to intensity in YIQ model, respectively. Then, panchromatic band is filtered by mean shift filtering for smoothing structures while preserving the discontinuities near boundaries. Next, differential morphological profile (DMP) is calculated for each pixel and a relative measure of structure size is recorded as the first maximum value of DMP which generates a labeled image representing connected components according to sizes of structures. However, there appear some connected components which are irrelevant to buildings in shape. To eliminate those connected components, their skeletons are obtained via thinning to get a relative length measure along with measuring areas of connected components. These measures are compared to a threshold individually, which provides a cue for a candidate building structure.","PeriodicalId":412236,"journal":{"name":"2009 4th International Conference on Recent Advances in Space Technologies","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116204968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
