SRA's seminar on Introduction to Computer Vision Fundamentals

Overview

Introduction to Computer Vision

This repository includes basics to :

  1. Python
  2. Numpy: A python library
  3. Git
  4. Computer Vision.

The aim of this repository is to provide:

  • A brief idea of algorithms involved in Computer Vision .
  • Introduction to Version Control System: Git and GitHub.
  • Computer Vision and Image Processing basics, idea of implementation of various algorithms involved using numpy (instead of any dedicated image processing library like OpenCV.)
  • Introduction to a commonly used Image Processing Library: OpenCV

  • Add suboptimal 2D convolution

    Add suboptimal 2D convolution

    This pull request intends to add a suboptimal implementation of generic 2D convolution. This is done for the purpose of giving a rough idea to Fys about how to work with python arrays/loops, etc. Fys will be asked to improve this implementation and complete tasks related to convolution on top of it.

  • Port to C++ : Assignments related to PIXELS seminar

    Port to C++ : Assignments related to PIXELS seminar

    Is your feature request related to a problem? Please describe. This feature request is created to keep a record of porting and potential addition of new assignments related to the seminar in C++ as discussed in this thread.

    Describe the solution you'd like

    • Create a separate main folder for containing all assignments. Individual assignments related to specific topics might be grouped together inside the main parent folder of assignments.
    • You might chose to add reference links in individual questions, which may provide additional material on a related topic for that question (this is suggested solely for the purpose of providing more (potentially real world) info related to the topic asked in original question and hence, should not in any way lead to the solution).

  • Add Content: Interpolations.

    Add Content: Interpolations.

    Is your feature request related to a problem? Please describe. As discussed in the thread, concepts of interpolation can also be added.

    Describe the solution you'd like

    • Create a implementations of interpolation from scratch using necessary OpenCV C++ API.
    • Add a Makefile to compile and build executables.
    • Add a .md file to explain the theory of interpolations and instructions to build and run the executables.

    Additional context Reference: Ancient Secrets of computer vision.

    Note: Content is not finalised and open for discussion

  • Add Content: Image Storing Formats.

    Add Content: Image Storing Formats.

    Is your feature request related to a problem? Please describe. As discussed in the thread, It is important to have a familiarity of how images are store.

    Describe the solution you'd like

    • Add the theory of basic image storing formats such as .bmp, .tiff, .jpg, png etc.
    • Implement a .cpp file on how image can be read from the bmp format.
      • Consider only 8 bit grayscale BitMap image (Since they are easy to read and contains only 2D form of data).
      • Use simple posix read() api to read the image bitmap file.
      • Directly storing the values of various attributes of image in struct is suggested.
    • A similar example can be added to demonstrate how to edit/write a grayscale bitmap image.
    • Add a Makefile to compile and build the executable.
    • Add a .md file explaining the theory and instructions to build and run the executables.

    Note: Content is not finalised and open for discussion.

    Add Content: Build Systems

    Is your feature request related to a problem? Please describe. As discussed in the thread, Concepts of Build System should be added.

    Describe the solution you'd like

    • Content should be added for manual creating and linking the object files.
    • Importance of build systems.
    • Add the contents for Makefile.
    • Add contents for Cmake.

    Additional context Can refer from here: Embedded Study Group Week 2.

    Add Content: C++ basic concepts for seminar.

    Is your feature request related to a problem? Please describe. Since the seminar is being ported to C++ as discussed in this thread, it is important to teach some important C++ concepts.

    Describe the solution you'd like

    • Some advance concepts of C++ like handling 2D arrays/vector, pointer etc.

    Note: Content is not finalised and open for discussion.
