顺序拟合 动机 如果我们有一个只能采样的未知函数f(x) ,我们可以选择一个以参数向量p特征的已知函数g(x,p) 。 用最小二乘法,我们可以找到p最小化的总和-的平方误差\sum_{x\in X}(g(x,p) - f(x))^2以设定的采样点的X 。 如果评估f昂贵,那么仔细选择采样点符合我们的利益。 假设我们的模型已经很不错了,我们可以使用它来找出下一步要采样的地方。 猜测要采样的点是x^* ,其中g(x^*,p)的p梯度尽可能大(这是我们最有可能从采样中学到的东西)的地方。 我们还希望避免在同一位置多次采样。 该程序包实现了这种顺序采样方法。 使用范例 using SequentialFit, Plots gaussian (x,mu,sigma) = exp ( - ((x - mu) / sigma) ^ 2 ) function expensiveFunction (x

Hands-On Computer Vision with Julia: Build complex applications with advanced Julia packages for image processing, neural networks, and Artificial Intelligence Explore the various packages in Julia that support image processing and build neural networks for video processing and object tracking. Key Features Build a full-fledged image processing application using JuliaImages Perform basic to advanced image and video stream processing with Julia's APIs Understand and optimize various features of OpenCV with easy examples Book Description Hands-On Computer Vision with Julia is a thorough guide for developers who want to get started with building computer vision applications using Julia. Julia is well suited to image processing because it's easy to use and lets you write easy-to-compile and efficient machine code. This book begins by introducing you to Julia's image processing libraries such as Images.jl and ImageCore.jl. You'll get to grips with analyzing and transforming images using JuliaImages; some of the techniques discussed include enhancing and adjusting images. As you make your way through the chapters, you'll learn how to classify images, cluster them, and apply neural networks to solve computer vision problems. In the concluding chapters, you will explore OpenCV applications to perform real-time computer vision analysis, for example, face detection and object tracking. You will also understand Julia's interaction with Tesseract to perform optical character recognition and build an application that brings together all the techniques we introduced previously to consolidate the concepts learned. By end of the book, you will have understood how to utilize various Julia packages and a few open source libraries such as Tesseract and OpenCV to solve computer vision problems with ease. What you will learn Analyze image metadata and identify critical data using JuliaImages Apply filters and improve image quality and color schemes Extract 2D features for image com
