# Syllabus

Computer Vision for Robotics steps

This Course syllabus is designed as follows :

(adsbygoogle = window.adsbygoogle || []).push({});

  1. Image Acquisition:

    Getting images form various source such as camera , video or images . Creating blank images and saving it for future usage

  2. Image Representation:

    Represent Images in a suitable data format so , it can be processed easily . Mostly it is represented as n-d array using numPY .

  3. Basic Operation:

    Modifying Images for displaying different effects which are done in Image editing software . Changing color scheme , Bluring, smoothing and generating shapes

  4. Detection:

    • Color Detection
    • Contour Detection
    • Line Detection
    • Corner Detection
    • Face Recognization
    • Sub Image Detection
    • Feature Detection
    • Object Detection

  5. Object Tracking:

    Track object using Optical Flow , CamShift and meanShift

  6. Robot Vision:

    This control the motion of robot based on the basic object detection

    • Line Following
    • Lane Detection and Tracking

# DISCLAIMER

This Computer Vision for Robotics course is a getting start with computer vision in robotics so , we can develop more intelligence machine to assist human race in future.

I hope to collaborate with you

# Requirement and Resource

This guide requires basic understanding of python . You can check yourself at learn python programming for robotics

All the code are found at : Github .

# Getting started

# 1. Download Code

Download or clone the GitHub repository Download .

If you downloaded the zipped version, unzip the directory somewhere you can access it.

# 2. Installing python

This simulator work with python 2.7.X.

# Linux, BSD and Unix users

You are probably lucky and Python is already installed on your machine. To test it type python on a command line.

If you have to install Python, just use the operating system's package manager or go to the repository where your packages are available and get Python.

# Windows users

Python doesn’t come prepackaged with Windows.

  1. Go to Python Download page .
(adsbygoogle = window.adsbygoogle || []).push({});
  1. Download python 2.7.x version
  2. Double-click the icon labeling the file python-2.7.x.exe.

# 3. Running code

In order to run code , Just move to code directory and type

python filename.py

# What is Computer Vision

Computer vision is the science of machines, robots, computer systems, and artificial intelligence analyzing images, recognizing objects, and acting accordingly.

In simple terms , In computer vision we extract data from images , videos, and high dimensional data and we make decision based on these data.

# Basic Terms

# Python

Python is an interpreted high-level programming language for general-purpose programming. Created by Guido van Rossum and first released in 1991, Python has a design philosophy that emphasizes code readability, notably using significant whitespace.

# PIP

pip is a package management system used to install and manage software packages written in Python. Many packages can be found in the default source for packages and their dependencies — Python Package Index. Python 2.7.9 and later, and Python 3.4 and later include pip by default

# Colorspaces

A color space is a specific organization of colors. In combination with physical device profiling, it allows for reproducible representations of color, in both analog and digital representations.

# Thresholding

Thresholding is the simplest method of image segmentation. From a grayscale image, thresholding can be used to create binary images.

# Image processing

The analysis and manipulation of a digitized image, especially in order to improve its quality.

# Gray-scale

In digital photography, computer-generated imagery, and colorimetry, a grayscale or greyscale image is one in which the value of each pixel is a single sample representing only an amount of light, that is, it carries only intensity information.

# Binary image

Binary image is a digital image that has only two possible values for each pixel. Typically, the two colors used for a binary image are black and white. The color used for the object in the image is the foreground color while the rest of the image is the background color.

# Optical Flow

Optical flow or optic flow is the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer and a scene. Optical flow can also be defined as the distribution of apparent velocities of movement of brightness pattern in an image.
