In imaging science, image processing is processing of images using mathematical operations by using any form of signal processing for which the input is an image, a series of images, or a video, such as a photograph or video frame; the output of image processing may be either an image or a set of characteristics or parameters related to the image. Most image-processing techniques involve treating the image as a two-dimensional signal and applying standard signal-processing techniques to it. Images are also processed as three-dimensional signals where the third-dimension being time or the z-axis.
Image processing usually refers to digital image processing, but optical and analog image processing also are possible. This article is about general techniques that apply to all of them. The acquisition of images (producing the input image in the first place) is referred to as imaging.
Closely related to image processing are computer graphics and computer vision. In computer graphics, images are manually made from physical models of objects, environments, and lighting, instead of being acquired (via imaging devices such as cameras) from natural scenes, as in most animated movies. Computer vision, on the other hand, is often considered high-level image processing out of which a machine/computer/software intends to decipher the physical contents of an image or a sequence of images (e.g., videos or 3D full-body magnetic resonance scans).
This video is just to understand what is Image Processing, its purpose and why is it important?.

Cameras are everywhere, even in your phone. You might have a new idea for using your camera in an engineering and scientific application, but have no idea where to start. While image processing can seem like a black art, there are a few key workflows to learn that will get you started. In this webinar we explore the fundamentals of image processing using MATLAB. Through several examples we will review typical workflows for: Image enhancement – removing noise and sharpening an image Image segmentation – isolating objects of interest and gathering statistics Image registration – aligning multiple images from different camera sources Previous knowledge of MATLAB is not required.

The robot arm controller is a Raspberry Pi 2 Model B. The Servomotors are Dynamixel AX-12A. There is a Raspberry Pi camera module mounted on the top for image processing. The Computer Vision algorithms applied here are Edge Detection, Binarization, Pixel Expansion, Labeling and Object Extraction. In this Video I tried to show how the robot see’s the world by adding pictures directly out of the Image Processing algorithms (I just added the coloring in the Labeling process). I also tried to sync the pictures to the superb music of the great artist “broke for free”. Here's some further info on the thing: I didn’t use OpenCV. The image processing algorithms applied here are all very simple. I wanted to write them by my own. Two important libraries which I used are pythons "picamera" and a ...
The gaussian blur algorithm is one of the most widely used blurring algorithms. It is accomplished by applying a convolution kernel to every pixel of an image, and averaging each value of each color channel of each pixel with the corresponding elements of the convolution matrix. You can also weigh the kernel so that each pixel processed takes a fraction of its neighboring pixels instead of the whole value. LIVE DEMO: http://easylearntutorial.com/live-demo/gaussian-blur-image-processing-algorithm.php The algorithm (source: WikiPedia) The Big-O value for the Gaussian blur algorithm is O(Kw * Kh * Iw * Ih), where K[w,h] and I[w,h] are the width and height of the kernel and image, respectively.

ECSE-4540 Intro to Digital Image Processing Rich Radke, Rensselaer Polytechnic Institute Lecture 13: Morphological image processing (3/19/15) Follows Sections 9.1-9.5 of the textbook (Gonzalez and Woods, 3rd ed.).
For downloadable versions of these lectures, please go to the following link: http://www.slideshare.net/DerekKane/presentations This lecture provides an overview of Image Processing and Deep Learning for the applications of data science and machine learning. We will go through examples of image processing techniques using a couple of different R packages. Afterwards, we will shift our focus and dive into the topics of Deep Neural Networks and Deep Learning. We will discuss topics including Deep Boltzmann Machines, Deep Belief Networks, & Convolutional Neural Networks and finish the presentation with a practical exercise in hand writing recognition techniques on the MNIST dataset.
