# Labeled Connectivity Analysis

Depending on the kind of image processing your application performs, you might want to perform blob analysis on images that are segmented into groups of pixels other than object and background pixels. For example, you might segment an image into four different groups of pixels, each group representing a different range of pixel values. This kind of segmentation is called labeled segmentation. When you perform connectivity analysis on an image that has undergone labeled segmentation, the connectivity analysis connects all pixels with the same label. With labeled connectivity there is no concept of object and background.
