# Blob Analysis

Once the image has been segmented, has been masked, and has undergone morphological operations and connectivity analysis, you can obtain the results of the blob analysis. Blob results are returned in the form of a blob scene description. A blob scene description is a data object that provides access to all the information about all features in the scene, including the number of features (blobs and holes), the topological relationship among the features, and the geometric and nongeometric properties of each feature.

In addition, the blob scene description also provides a number of computed blob measures based on the fundamental blob attributes listed above. The specific information contained in a blob scene description is listed below.
