Counting Objects in Images
Counting Objects in Images
Using only a few lines of code, it is possible to count the number of objects in a image. It is important to do the image acquisition with a standard background.
There are some basic steps:
1. Original image.2. Apply a Gaussian filter to reduce image noise.3. Binarize to get only a black-and-white binary image.4. Count the number of elements (white spots) with Mathematica's built-in function ComponentMeasurements, which returns a list with the center of each cluster.5. Original image with objects counted.
