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.

Computer vision research conferences

Some of the conferences to look for latest research and applications are as follows:

CVPR: Conference on Computer Vision and Pattern Recognition is held every year and is one of the popular conferences with research papers ranging from both theory and application across a wide domain
ICCV: International Conference on Computer Vision is another major conference held every other year attracting one of the best research papers
SIGGRAPH: Special Interest Group on Computer Graphics and interactive techniques though more on computer graphics domain has several applications papers that utilizes computer vision techniques.

Other notable conferences include Neural Information Processing Systems (NIPS), International Conference on Machine Learning (ICML), Asian Conference on Computer Vision (ACCV), European Conference on Computer Vision (ECCV), and so on.
