What is Image Processing?

Digital image processing is the practice of applying computer-based intelligence algorithms for analyzing digital images. Ultimately, these digital developments are more capable than traditional analog employment for dealing with challenging techniques to the image.

 This page is about the latest research developments in the Digital Image Processing Area and the importance of Python in the DIP research field!!!

By the by, the most important operations involved in digital image processing are affine transformations and filtering. Majorly, it relies on analyzing the image for a better interpretation of humans and machines. To be exact, it operates on two-dimensional images to convert one image into another form by applying the required techniques.

Here, we have mentioned the few scientific disciplines that majorly intersect with digital image processing,

• Biological Vision
• Signal Processing
• Pattern Recognition
• Machine Learning
• Digital Electronics
• Artificial Intelligence
• Robotics and Robot Vision
• Machine / Computer Vision

As mentioned earlier, it is used in many engineering disciplines to support numerous digital image processing applications. And, some of them are given below for your reference.

• Biometrics Authentication (face, iris recognition, and fingerprint recognition)
• Digital Image Manipulation, Denoising, Improvement, Rectification, etc.
• Remote Sensing (Image Processing on satellite and aerial photographs)
• Industrial Applications (product assessment and particle structure identification)
• Medical Diagnostics using Clinical Image Analysis
• Space / Astronomical
• Image Processing (starting from Hubble images to ground-based telescopes) 

What are the Steps in Image Processing?

• Step 1: Image Acquisition (Obtaining Image(s) as Input)
• Step 2: Image Enhancement (Improving Image Quality)
• Step 3: Image Restoration (Recovering Original Image)
• Step 4: Color Image Processing (Simplifying Object Identification)
• Step 5: Wavelets Analysis (Evaluate the Adaptive Changes)
• Step 6: Image Compression (Minimize actual image size without affecting quality)
• Step 7: Morphological Processing (Analyze the Morphological Features of Image)
• Step 8: Image Segmentation (Partition the Image into Multi-Parts based on certain Constrains)

From the above, we have selected the “color conversion” step for demonstration purposes. Here, we just let you know about the implementation steps for the color conversion process. 

Color Conversion Flow Diagram 

• Step 1: Make the ready camera.
• Step 2: Capture the image from the camera
• Step 3: Next, apply a filter on duplicated image to minimize the noise
• Step 4: Then, transform the smoothen image into an HSV model
• Step 5: After that, acquire the HSV value from the HSV model
• Step 6: If HSV value match with the current value, then assign saturation, flag value, and color; else again, get the HSV value
• Step 7: Next, apply a filter on HSV image and detect the edge
• Step 8: Then, make the highlights on the required edges
• Step 9: Afterwards, print the captions and highlights on the actual image
• Step 10: View the output on the visual screen

In fact, there are three matrices in a single colored image to represent three different channels such as Red channel, Green channel, and Blue channel (RGB). When you are handling a color image, it is necessary to know about these channels. 

Installation of Python for Digital Image Processing Projects 

Note: For integrating the OpenCV library for your Digital Image Processing Projects using Python, Python (version 3) is needs to be installed on your system. After installation, run “import cv2” command in either command prompt or python shell to know whether the installation was completed successfully or not.

• Linux$
  • sudo apt-get install libopencv-dev python-opencv
• MacOS
  • $ brew install opencv3 –with-contrib –with-python3
• Windows
  • $ pip install opencv-python

For instance, in image processing, classifiers play a significant role in training and modeling the data to figure out the various image features for categorization. For user ease, it offers the provision to create customized classifiers for pattern recognition, object recognition. The below steps will give a clear idea about creating your own classifier in Windows,

• Gather images for a database
• Organize the Negative Images
• Mark Positive Images and Crop them
• Create a Positive Images Vector
• Accomplish the Haar Cascade Training
• Build the XML file

Most importantly, Python three is furnished with massive libraries to satisfy the needs of scholars or developers to build their desired Digital Image Processing Projects using Python. These python libraries support small-scale and large-scale data sets for performing all kinds of data engineering operations to make effective decisions. Further, we have given the special features that make Python 3 unique from other versions, 

Exclusive new features of Python 3 

• Chained Exception
• Unicode Separation by Bytes
• Extended Unpacking of Tuple
• Unicode Strings (in default)
• Declaration of Non-local Variables
• “Keyword-only” Arguments Syntax
• Function Annotations (add metadata to function return value and parameters) 

Which Python Library is used for Image Processing?

Python Imaging Library is shortly referred to as PIL. The Python enabled open-source library specially designed for processing digital images such as image reading, storing (in jpg, gif, png, bmp, etc.), and rescaling in dip projects. As well, it is commonly used for image representation, image analysis, and image archives.

Nowadays, computer vision and digital imaging demand are growing at ultra-speed over all edges of IT engineering. By knowingly or unknowingly, we are experiencing these services through many real-time solutions. Also, it paves the way for dealing with complex problems in digital software and hardware systems.

Similar to DIP, computer vision is also on the rise of geometric progression in parallel. And, the well-defined technologies and algorithms used in these areas, web and mobile projects are intentionally used to enhance data science and image informatics. We can support other programming languages libraries as follows,

To a great extent, computer vision and image processing support a large volume of different programming languages libraries. On the one hand, these languages are majorly used in the backend process, such as Ruby, C#, and Java. On the other hand, some of the languages are used in the front-end process, such as JavaScript. Here, we have listed out some important characteristics that need to note down in Python DIP projects, 

Key Features of Digital Image Processing Projects Using Python

• Write Text on Images
• Single Pixel Manipulations
• Image Filtering (Contouring, Edge Detection, Blurring, Smoothing)
• Image Mask And Transparent Overlays Management
• Image Enhancing (Adjusting Brightness, Color, Sharpening, Contrast)
• And many more
