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.

Summary

In this chapter, two different computer vision problems were shown. In segmentation, both the pixel level as well as convolutional neural net-based methods were shown. FCN shows the effectiveness of segmenting an image using the feature extraction method and, as a result, several current applications can be based on it. In track, two different approaches were discussed. Tracking by detection and tracking by matching can both be used for applications to track objects in the video. MOSSE tracker is a simple tracker for fast-paced applications and can be implemented on small computing devices. The Deep SORT method explained in this chapter can be used for multi-object tracking that uses deep CNN object detectors.

In the next chapter, we will begin with another branch of computer vision that focuses on understanding geometry of the scene explicitly. We will see methods to...
