Analysis, Search, and Display. This new software is a widely applicable, crosscutting technology. The labeling tool greatly facilitates the identification of region segments and the selection of appropriate levels of segmentation detail. These more general applications would be keyed on making a set of hierarchical image segmentations a generally available standard data product.
Image segmentation is a partitioning of an image into sections or regions.
The regions consist of groupings of multispectral or hyperspectral image pixels that have similar data feature values. Image segmentation is a key first step in a number of approaches to image analysis and image compression. In image analysis, the group of pixels contained in each region provides a good statistical sampling of data values for more reliable labeling based on multispectral or hyperspectral feature values. In addition, the region shape can be analyzed as an additional clue for the appropriate labeling of the region. In image compression, the regions form a basis for a compact representation of the image data.
