1. A method of image data processing and collecting processed data in a designated database, comprising the following steps: selecting image data from a source file, wherein the image presents a structure spanned within multiple space regions in a standard area; dividing the image with voxels, and defining each space region with different characters; transforming spatial distribution information of the image into a sequence of characters, which is simplified as space code; and collecting the image data and the results of the previous step into a computer-readable recording medium.
