Practical Computer Vision

By: Abhinav Dadhich

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.

Datasets

In computer vision, datasets play a key role in developing efficient applications. Also, now, with the availability of large open source datasets, it has become much easier to create best performing models for computer vision tasks. In this section, we will see several datasets for computer vision.

ImageNet

ImageNet is one of the largest annotated datasets for computer vision. The data is arranged according to a hierarchical order. There are 1,000 classes with 1.4 million images overall. Though the images are for non-commercial use, ImageNet is still one of the most popular datasets when it comes to learning computer vision. Especially in deep learning, the dataset is used to create image classification models due...
