template matching

Simple Template Matching with Variable Image Template Ratio: In this process, we aim to locate the template Itm (binary image) within the Is (grayscale image) using a canny edge-detected version of Is. The template matching method accommodates scaling, meaning the template size doesn't have to match the exact target size in the main image, allowing for scanning at various scale ratios of Itm. Input:- Is: The main color image containing the target.- Itm: The binary image of the template. Output:- Best Match Location (x, y): Coordinates of the optimal match.- Matching Score: Quality score of the best match.- Resized Image and Template: Outputs the resized main image and template for the best scale ratio found. Methodology:1. Edge Detection: Convert Is to a canny edge-detected image.2. Scale Adjustment: Iterate through various size scales of Itm and Is.3. Template Matching with Cross-Correlation: Utilize a cross-correlation approach to match edges between Is and Itm.4. Result Visualization: Display Is with the optimal match position highlighted. Primary Function: MAIN_find_template_in_image

Function temp_matching(t1, t2, upl_1, lor_1, upl_2, lor_2, th, cal) Function Purpose This function performs image matching between two input images. The process utilizes upper and lower coordinates for both images to match corresponding features based on a threshold and calculation method. Input Parameters: t1, t2: Input image data. upl_1, lor_1: Upper and lower boundary coordinates of image 1. upl_2, lor_2: Upper and lower boundary coordinates of image 2. th: Threshold value for matching. cal: Calculation method for matching accuracy. Output Variables: mt1, mt2: Matched points in image 1 and image 2. upl_mt1, lor_mt1: Upper and lower boundary coordinates for matched points in image 1. upl_mt2, lor_mt2: Upper and lower boundary coordinates for matched points in image 2. match_weight: Matching confidence weight. err: Error term indicating matching accuracy. Key Concepts: Image matching is crucial in computer vision tasks for feature recognition, alignment, and more. This function helps achieve optimal alignment between two sets of data by considering boundary and threshold conditions.

数据结构-匹配括号（栈） 本节课程主要讲解了使用栈来实现括号匹配的算法。栈是一种基本的数据结构，可以用来解决括号匹配问题。 栈的定义栈是一种后进先出（LIFO）的数据结构，它可以用来存储和检索数据。栈的结构体可以用C语言中的结构体来定义，如下所示： typedef struct Stack { elemtype data[Maxsize]; int top; } Stack; 其中，data是元素数组，top是栈顶指针。栈的基本操作包括入栈、出栈和判断栈是否为空等。 入栈操作入栈操作是将元素压入栈中。入栈操作的实现代码如下所示： Stack Push(Stack& S, elemtype e) { S.top++; S.data[S.top] = e; return S; } 出栈操作出栈操作是将栈顶元素弹出栈。出栈操作的实现代码如下所示： Stack Pop(Stack& S, elemtype& e) { e = S.data[S.top]; S.top--; return S; } 判断栈是否为空判断栈是否为空的操作是检查栈顶指针是否等于-1。如果等于-1，则栈为空。实现代码如下所示： bool Isempty(Stack S) { if (S.top == -1) { return true; } else { return false; } } 括号匹配算法该算法用于检查括号是否匹配。代码如下所示： bool BreacketCheak(Stack S, char arr[], int n) { elemtype s; int i = 0; int x = 0, y = 0; if (n % 2 != 0) { return false; } if (n % 2 == 0) { while (i < n xss=removed xss=removed xss=removed xss=removed xss=removed xss=removed xss=removed xss=removed xss=removed xss=removed>

相似图像匹配与搜索 知识点概览 相关系数：衡量两个变量之间线性关系强度的统计量。 汉明距离：一种度量两个同长度序列之间差异的方法。 归一化互相关法：用于评估图像之间相似度的一种方法。 互相关值：描述两个信号之间相似度的度量。 相关系数 相关系数用于评估两幅图像之间的相似度，取值范围在-1到+1之间。其计算公式为： [ r_{AB} = \frac{\sum_{i=1}^{n}(A_i-\bar{A})(B_i-\bar{B})}{\sqrt{\sum_{i=1}^{n}(A_i-\bar{A})^2} \sqrt{\sum_{i=1}^{n}(B_i-\bar{B})^2}} ] 根据相关系数的不同取值，可以将图像间的相似度分为几个等级：- 0.8 < r>- 0.6 < r>- 0.4 < r>- 0.2 < r>- 0.0 < r> 汉明距离 汉明距离用于度量两个同长度序列之间的差异，定义为不同位的数量。其计算公式为： [ H(u,v) = \sum_{i=1}^{n} [ u_ieq v_i ] ] 归一化互相关法 归一化互相关法（NCC）是一种常用的图像匹配技术，能有效处理亮度变化，具有旋转和平移不变性。其计算公式为： [ NCC(A,B) = \frac{\sum_{i,j}(A_{ij}-\bar{A})(B_{ij}-\bar{B})}{\sqrt{\sum_{i,j}(A_{ij}-\bar{A})^2}\sqrt{\sum_{i,j}(B_{ij}-\bar{B})^2}} ]

Cart Pendulum Template for MATLAB - This guide provides an overview of the MATLAB code for simulating the dynamics of a cart-pendulum system using the RDS2020 framework. The primary entry point of the application is main.m, which utilizes various dynamics-related functions through a wrapper. These functions are generated automatically by running derive_equations.m. Important: You must run derive_equations.m before main.m to initialize the required dynamics functions. Workflow: Symbolic Computation: derive_equations.m employs symbolic computation to create the cart-pendulum’s state-space dynamics. It exports this as MATLAB functions (e.g., autogen_drift_vector_field.m and autogen_control_vector_field.m). Controller Design: You can experiment with controller design in main.m. For certain controller types, a middleware layer may be necessary to customize control functionality. Note to Students: This code requires additional setup before it can run. You must complete derive_equations.m where you see TODO lines to finalize certain parts of the code.
