An Interdisciplinary Introduction to Image Processing: by Steven L. Tanimoto

By Steven L. Tanimoto

This ebook explores picture processing from numerous views: the artistic, the theoretical (mainly mathematical), and the programmatical. It explains the elemental rules of snapshot processing, drawing on key strategies and methods from arithmetic, psychology of notion, desktop technological know-how, and paintings, and introduces laptop programming which will get extra keep an eye on over snapshot processing operations. It does so with out requiring college-level arithmetic or previous programming adventure. The content material is supported by means of PixelMath, a freely on hand software that is helping the reader comprehend pictures as either visible and mathematical gadgets.

The first a part of the e-book covers such issues as electronic snapshot illustration, sampling, brightness and distinction, colour types, geometric modifications, synthesizing photos, stereograms, photomosaics, and fractals. the second one a part of the ebook introduces computing device programming utilizing an open-source model of the easy-to-learn Python language. It covers the fundamentals of snapshot research and development popularity, together with aspect detection, convolution, thresholding, contour illustration, and K-nearest-neighbor type. A bankruptcy on computational images explores such topics as high-dynamic-range imaging, autofocusing, and strategies for immediately inpainting to fill gaps or eliminate undesirable gadgets in a scene. purposes defined comprise the layout and implementation of an image-based online game. The PixelMath software program presents a "transparent" view of electronic pictures via permitting the consumer to view the RGB values of pixels via zooming in on a picture. PixelMath presents 3 interfaces: the pixel calculator; the formulation web page, a complicated extension of the calculator; and the Python window.

Text Processing in Python

Textual content Processing in Python describes innovations for manipulation of textual content utilizing the Python programming language. on the broadest point, textual content processing is just taking textual info and doing anything with it. this is able to be restructuring or reformatting it, extracting smaller bits of knowledge from it, or appearing calculations that rely on the textual content.

Learning IPython for Interactive Computing and Data Visualization

Learn IPython for interactive Python programming, high-performance numerical computing, and knowledge visualization.

Overview

• a pragmatic step by step instructional so one can assist you to interchange the Python console with the robust IPython command-line interface;
• Use the IPython computer to modernize how you have interaction with Python;
• practice hugely effective computations with NumPy and Pandas;
• Optimize your code utilizing parallel computing and Cython.

In aspect

You already use Python as a scripting language, yet do you know it's also more and more used for clinical computing and knowledge research?

Example text

The storage area is protected from the light, so that any change in the charge there is minimized. From there, all the charges from the many storage areas can be shifted over to an analog-to-digital (A/D) conversion circuit, typically on the same semiconductor chip as the array of photosites. The A/D unit produces numerical representations of the charge magnitudes. These numbers are then transferred from the sensor chip to a bulk storage unit such as a CompactFlash memory card. Before the image data are written on the flash memory card, they may be digitally enhanced within the camera and then reduced in volume using a method such as JPEG compression.

14. As mentioned before, there are two ways of using PixelMath: as an application on your computer or as an applet on the web. In application mode, you can navigate throughout your file system to find the image you want. png files. ” and you’ll see a list of files that are on the server and that are currently available to your PixelMath applet. 14b. It’s also possible to upload an image file to the server from your PC in order to make it available to PixelMath. 12 (plate 5) PixelMath startup: (a) the launch pad and (b) the calculator with the cover still closed.

One way to obtain value is to extract information. 10 Exercises 19 the pixels into beautiful objects (art). If we cannot obtain value or add value, we could of course delete images and recover disk space, memory space, etc. Or we could save the images but compress them to recover at least some of the space they take on disks. How do we do these things that add value or save space? That’s part of what this book is about. More than that, this is a book about empowering you to work with digital images using the rich languages of mathematics and computer programming, and about helping you understand at least some aspects of how the Internet and the objects in it really work.
