Statistics for labeled regions
Computer Vision Toolbox / Statistics
The Blob Analysis block calculates statistics for labeled regions in a binary image. The block returns quantities such as the centroid, bounding box, label matrix, and blob count. The Blob Analysis block supports input and output variable-size signals. You can also use the Selector (Simulink) block from Simulink®, to select certain blobs based on their statistics.
For information on pixel and spatial coordinate system definitions, see Image Coordinate Systems and Coordinate Systems.

[a] Generated code will be restricted to MATLAB host computers when you set the FFT implementation parameter to FFTW, or when the transform length is not a power of two. [b] This data type is supported at the output port(s). [c] Fixed-point data types are not supported at the Major Axis, Minor Axis, Orientation, and Eccentricity output ports. |
