How do you detect a Blob?

A natural approach to detect blobs is to associate a bright (dark) blob with each local maximum (minimum) in the intensity landscape. A main problem with such an approach, however, is that local extrema are very sensitive to noise.

What is blob detection in OpenCV?

A Blob is a group of connected pixels in an image that share some common property ( E.g, grayscale value ). In the image above, the dark connected regions are blobs, and blob detection aims to identify and mark these regions.

What is Blob in image processing?

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 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.
