There is the concept of connected domain in mathematics, image processing and other fields. Today, I will tell you about the functions that extract the connected domain in matlab? 1, bwlabel function bwlabel function is the simplest function to be introduced today. Its usage is as follows: % Binary image data BW = [ 0 1 0 0 0 ...

Written by @hzj //JinXing Project #2021.11.21 V1.0 1. Fixed point positioning of filter and use of Beyond compare (1) Why fixed-point positioning? 1. Fixed point: the existence of fixed point is due to the binary operation inside FPGA. The decimal point (floating-point data) in the actual operation cannot be accurately represented by bi ...

Pyplot is a sub Library of Matplotlib, which provides a drawing API similar to MATLAB. Pyplot is a commonly used drawing module, which can easily allow users to draw 2D charts. Pyplot contains a series of related functions of drawing functions. Each function will make some modifications to the current image, such as marking the image, generatin ...

1, PNN probabilistic neural network speech emotion recognition 1 speech emotion recognition system In the speech emotion recognition system, the recorded corpus contains five different emotions of five actors, namely happiness, fear, sadness, anger and neutrality. At the same time, the corpus is divided into training set and test set. The desi ...

MATLAB is a powerful software and is widely used in the field of automatic control. This series of blog posts will be based on control system simulation. Refer to the book MATLAB/Simulink and control system simulation. This series of blog posts and the author's automatic control theory (postgraduate entrance examination) complement each other. ...

Next, I will use three examples to learn the trajectory planning of seventh degree polynomial with you. The first one has a problem and we look forward to solving it together. Is it just caused by the solution of inverse solution? The first model is the GLUON-6L3 manipulator in the previous paper clear;clc;close all; % DH Modeling part theta, ...

Using matlab to filter the noisy sine wave signal This is my little job. There may be all kinds of small errors in the program. Firstly, the sinusoidal signal is generated, different signal-to-noise ratios are set, and the moving average filter is designed to filter the noisy signal. For a fixed signal-to-noise ratio, the influence of the order ...

1, Introduction to sift algorithm Scale invariant feature transform (SIFT) is a computer vision algorithm used to detect and describe local features in images. It looks for extreme points in spatial scale and extracts their position, scale and rotation invariants. This algorithm was published by David Lowe in 1999 and summarized in 2004. Its ...
