| Research Abstract |
The purpose of this research was twofold. The first one is to develop new algorithms for hierarchical processing of remotely sensed multispectral data. The other is to make a software package including the hierarchical processing algorithms for the images above..
In the first one, we aimed at extending the functions of the algorithms we had already developed, and also developing new algorithms. We refined algorithms for automatic registration to make highly efficient one. The algorithm is to register multispectral images by dividing images into small triangles and by transforming then by a linear transform to match the triangles with each other. We developed also new classification algorithms. In one of them we devised a method to estimate a priori probability for each category using spatially hierarchical structure of the image to achieve high accuracy. We also succeeded high accuracy and high efficiency at the same time by developing purpose-oriented feature extraction algorithm.
In the realization of software package, we discussed to finalize the system structure of the package, unifying the specification of input and output image data format, the interface among the algorithms and user interface. We included several algorithms into the package which are "automatic registration algorithm, ""un-supervised classification (clustering) algorithm, " and "binary decision tree classification algorithm."
