Howtosignalprocessing
The method of analyzing an image that has undergone binarization processing is called "blob analysis". A blob refers to a lump. Blob analysis is image processing's most basic method for analyzing the shape features of an object, such as the presence, number, area, position, length, and direction of lumps.

What becomes blob in an image?
A Blob, in a sense, is anything that is considered a large object or anything bright in a dark background, in images, we can generalize it as a group of pixel values that forms a somewhat colony or a large object that is distinguishable from its background. Using image processing, we can detect such blobs in an image.
What is blob detection used for?
In computer vision, blob detection methods are aimed at detecting regions in a digital image that differ in properties, such as brightness or color, compared to surrounding regions.
What is blob analysis in Matlab?
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.
What is a blob in Opencv?
Blob stands for Binary Large Object and refers to the connected pixel in the binary image. The term "Large" focuses on the object of a specific size, and that other "small" binary objects are usually noise.
What is blob in vision?
Blobs are sections of the visual cortex where groups of neurons that are sensitive to color assemble in cylindrical shapes. They were first identified in 1979 by Margaret Wong-Riley when she used a cytochrome oxidase stain, from which they get their name.
What is blob filtering?
A Blob filter is a routine that translates Blob data from one subtype to another. InterBase includes a set of special internal Blob filters that convert from subtype 0 (unstructured data) to subtype 1 ( TEXT ), and from subtype 1 to subtype 0.
