  • This perhaps is a problem for blobs, as the connecting pixels will have a different property. The better defined the target is, in terms of pixels, the better the blob detector will be. I suspect blob detector would work very well on a classified satellite image. This is just one example.

BLOB DETECTION. Follow 92 views (last 30 days) Ziaul Haque Choudhury on 31 Oct 2011. Vote. 0 ⋮ Vote. 0. Answered: Image Analyst on 10 Apr 2015 A few words of introduction. A blob is a region of an image (a group of connected pixels) shares some common properties. The main objective of blob detection methods and algorithms is to detect image regions that differ in these properties. Here we decided to use OpenCV approach as a SimpleBlobDetector class, based on a rather simple algorithm ...
Nov 13, 2020 · Blob tracking is a method by which computers can identify and trace the movements of objects within images. A blob is a group of pixels the computer identifies as an object. A person, for example, could be a blob. This tracking method allows the computer to find the blob’s position in successive frames.

Example of Face Detection using OpenCV in Python. We will discuss how we can apply Face Detection using OpenCV. We go straightforward with a practical reproducible example. The logic it the following: We get the image from the URL (or from the hard disk). We convert it to an numpy array and then to a grayscale.

Using contours with OpenCV, you can get a sequence of points of vertices of each white patch (White patches are considered as polygons). As example, you will get 3 points (vertices) for a triangle, and 4 points for quadrilaterals. So, you can identify any polygon by the number of vertices of that polygon.
