Image Processing and Counting using MATLAB
7 Steps

This is fun project based on image processing with MATLAB, here we will come accross learing how to count the number of distinguishable objects in an image. Sounds fun ,dosen’t it …So lets get started!

The following tutorial is performed with the help of MATLAB. MATLAB stands for “MATrix LABoratory” and is a numerical computing environment and fourth-generation programming language, developed by MathWorks. Using MATLAB, we can solve technical computing problems faster than with traditional programming languages, such as C, C++, and Fortran.

The tutorial can be performed by executing the commands in each step sequentially in the command window of MATLAB.

## Step 1: Read the Image

An image is choosen so that it has considerable contrast with its background so that the objects can be identified. The function imread reads the image from a given location and stores it in the matrix img1. The imshow function displays the image.

imshow(img1)

NIce work done. Like this can u tell how to detect objects in an image and find their locations. It will be very useful.

It is possible that the objects appear overlapped in image. Is it still possible to count their numbers?

My girlfriend had to do something like this for a class using Matlab. Too bad she didn't read this first!

Great work, I think everyone should learn the basics like this! You could also use the watershed filter to pick our objects not so clearly defined. It could be useful to show something like that as an next step for people who want to try it with any blob structures that may touch.

maybe im planning 2 fill those up in my next instructable. Thanx anyway!!

When I first looked at that first image, I thought it looked familiar but I couldn't place it. When I closed out of the browser twenty minutes later, i realized that my desktop has that as the background. That's basically my life for you.
