Overview of this book

In this book, you will find several recently proposed methods in various domains of computer vision. You will start by setting up the proper Python environment to work on practical applications. This includes setting up libraries such as OpenCV, TensorFlow, and Keras using Anaconda. Using these libraries, you'll start to understand the concepts of image transformation and filtering. You will find a detailed explanation of feature detectors such as FAST and ORB; you'll use them to find similar-looking objects. With an introduction to convolutional neural nets, you will learn how to build a deep neural net using Keras and how to use it to classify the Fashion-MNIST dataset. With regard to object detection, you will learn the implementation of a simple face detector as well as the workings of complex deep-learning-based object detectors such as Faster R-CNN and SSD using TensorFlow. You'll get started with semantic segmentation using FCN models and track objects with Deep SORT. Not only this, you will also use Visual SLAM techniques such as ORB-SLAM on a standard dataset. By the end of this book, you will have a firm understanding of the different computer vision techniques and how to apply them in your applications.

Transformation of an image

Transformation operations on an image are usually referred to as geometric transformations, applied on a photo. There are several other kinds of transformations as well but in this section we will refer to geometric transformations. These consist of, but are not limited to, shifting an image, rotating an image along an axis, or projecting it onto different planes.

At the core of transformation is a matrix multiplication of our image. We will look at different components of this matrix and the resulting image.

Translation

Displacement of an image in any direction can be done by creating a transformation matrix and applying the transformation to our image. The transformation matrix for translation...
