Introduction

In today’s era of digitalization, image processing plays a very important role in various fields such as medical imaging, robotics, agriculture, and many more. In image processing, counting the color shapes in an image is a tedious task, but Python helps us with its powerful libraries to simplify it.

Comparison with Traditional Methods

Earlier, traditional methods were used for counting colored shapes in images, which were time-consuming and prone to errors. These traditional methods involved identifying each shape manually and counting them one by one. But with the use of Python programming, this process has become very simple and efficient.

Accuracy

The accuracy in traditional methods is not up to the mark as human errors are possible while precisely locating, defining, and recognizing the shapes. In the case of Python, the program can strictly follow the predefined algorithms without errors (if written correctly).

Time Efficiency

Traditional methods could take up several hours for counting the colored shapes in images, while Python takes just a few minutes to complete the same task.

Python Libraries for Image processing

Pillow : This library is capable of opening different formats of image files like BMP, PPM, JPEG, GIF, PNG, and more. It also provides some essential features for image manipulation, such as cropping, resizing, and rotating, making it easier for image analysis and processing.

Scikit-image : It is one of the widely used libraries for image processing in Python that includes different classes and functions to handle different image processing tasks. Scikit-image has multiple algorithms that work well on binary, grayscale, and color images.

OpenCV : OpenCV is the most widely used library for image processing and computer vision. It provides a wide range of features from basic image manipulation (resizing, cropping, rotating) to advanced machine learning techniques.

Python Code for Counting Colored Shapes in an Image

In the following code snippet, we will use the Scikit-image library for counting colored shapes in an image. The steps involved are:

  1. Convert Image to Grayscale: The image is converted into a grayscale image so that edges and contours can be detected.
  2. Thresholding: Thresholding is used to convert the grayscale image into a binary image for easy detection of edges.
  3. Edge Detection: The edges are detected using the Canny edge detection algorithm.
  4. Counting Shapes: The number of shapes is counted based on the number of contours detected using the findContours() function.

Opinion on Python Method for Counting Colored Shapes in Images

Python is an excellent tool for counting colored shapes in images as it simplifies the process and provides several libraries that can be used to get the job done efficiently. The accuracy and time efficiency provided by Python make it a better option than traditional methods. Therefore, using Python for image processing tasks is a good choice.

Conclusion

Counting colored shapes in an image was a tedious and time-consuming task earlier but with Python’s powerful libraries, this process has become very efficient and accurate. By using the Scikit-image library for counting colored shapes, we can also save a lot of time and efforts. Python offers an automated approach with a low possibility of errors. Hence, Python is a great tool for image processing and counts colored shapes in images.
