What is Image Processing?

Image processing is the computational transformation of images. This unremarkably involves working with computer languages to work on image as a 2 dimensional betoken through its pixel composition. Image processing too is a branch of signal processing.

Image Editing

Image editing can be the same outcomes of irresolute, altering, editing, enhancing the prototype but information technology usually implies doing those things through gui of paradigm editing software and non as a vector or point.

Image Processing vs Image Manipulation

Image manipulation, image processing and image editing can all be used interchangeably depending on the context however, one scenario image manipulation differs from image editing is that image manipulation can refer to more substantial changes such as moving objects, removing people, adding object, changing scene etc while image editing can be more appropriate for paradigm enhancing, resizing, rotating type operations.

What is PIL (pillow)?

PIL is an imaging library for Python programming linguistic communication.

Script is a slice of code that's used to automate organization oriented tasks. When you write code that carries out a practical task without needing compiling this tin can be called scripting.

PIL has very powerful epitome processing capabilities and it can handle many types of images (BMP, DIB, EPS, GIF, ICO, IM, JPEG, JPG, JPEG 2000, MSP, PCX, PNG, PPM, SGI, TGA, TIFF, WebP, XBM just to proper name a few formats) and image modes such as RGB, RGBA, B&Due west and monochrome.

PIL likewise works on practically all operating systems including,Windows,Linux, andMacOSX.

PIL 5.southward. pillow

Pillow is a fork of PIL, Python Imaging Library. PIL was released in late 2009 and maintained until 2022. In 2022 PIL development stopped. Luckily PIL cruel on a soft place since pillow library picked up from where information technology'southward left and it continues to exist as pillow today.

This can create some terminology defoliation simply it'due south condom to say that pillow and PIL refer to the same thing in most situations today every bit the terms became somewhat synonymous.

How to Install PIL (pillow)

            pip install Pillow or pip3              install Pillow                      

Normally used PIL (pillow) Modules

• Image : Nearly fundamental epitome operations can be washed with information technology such equally:
  • opening an image, showing an image, saving an epitome,
  • managing alpha transparency channels,
  • converting between image modes,
  • merging, blending and combining images,
  • copying and pasting images,
  • creating new images or image layers,
  • reading from and writing to prototype pixels
  • Cropping, rotating, resizing, flipping images
  • Transposing images
• ImageEnhance : Tin exist used for paradigm enhancement operations regarding; color, contrast, brightness and sharpness via these classes:
  • PIL.ImageEnhance._Enhance
  • PIL.ImageEnhance.Color
  • PIL.ImageEnhance.Contrast
  • PIL.ImageEnhance.Brightness
  • PIL.ImageEnhance.Sharpness
• ImageDraw : Useful to depict pretty much anything on an epitome.
• ImageFont : Used to create a font wrapper which tin can be used to draw text on images (supports bitmap and truetype fonts)
• ImageGrab : Useful to get contents of screen or from the clipboard. Similar function to the printscreen fundamental on keyboard.
• ImageFilter : Includes common useful filters that can be applied to images via many different means such as pixel thresholds, based on minimum pixels, maximum pixels, median pixels etc. Furthermore, these filter objects tin exist applied via a number of methods such as gaussianblur, boxblur, unsharpmax etc.
  • BLUR,
  • CONTOUR,
  • DETAIL,
  • EDGE_ENHANCE,
  • EMBOSS,
  • FIND_EDGES,
  • Acuminate,
  • Smoothen
• ImageCms: Image color profile management.
• ImageStat : Getting global statistics of images at pixel level such as; mean, minimum, maximum, count, sum, variance, standard divergence of pixels at each band.
• ImageColor : Colour table conversion operations

PIL has even more modules but near people will probably use top 6 modules listed here in well-nigh cases.

An Paradigm from PIL tutorials

Resource

• PIL has a documentation that's quite extensive which tin can exist found here.
• If you'd like to support your learning with watching a video, here is a relatively brusque Youtube tutorial (~15mins) explaining most basic operations in pillow very well and clearly, video below.

Summary

We have learned some digital prototype basics in this Python tutorial. Before agreement the fundamentals of digital images it's harder to carry out prototype processing operations with coding. Nosotros take too antiseptic some of the digital imaging terms such as image processing and image manipulation.

In one case you sympathise each pixel consists of numerical data it becomes a breeze to write Python code to do all kinds of imaging operations.

Then, nosotros have explainedhow to edit images in Python using PIL (pillow) library through PIL tutorials with Python.

Nosotros have too seen other prototype editing tutorials such as how to resize images as a batch, how to tell different pixels between images etc.
