1, Introduction 1 Introduction to LSB algorithm The full name of LSB is Least Significant Bit (LSB), which is a simple and effective data hiding technology. The basic method of LSB steganography is to replace the lowest bit of the carrier image with the secret information to be embedded. The high-order plane of the original image and the lowes ...

Non ranging location algorithm This kind of localization algorithm estimates the target by relying on the physical deployment of the observation station and the simple binary detection information of "yes" and "no" of the detected target. There are mainly centroid localization algorithm, weighted centroid localization a ...

preface Digital filtering technology is an important part of digital signal processing, and the design of filter is one of the core problems of signal processing. IIR(Infinite Impulse Response) digital filter, also known as "infinite impulse response digital filter" or "recursive filter", is generally considered to have inf ...

MATLAB vector type: Row vector Column vector MATLAB line vector: Creates a collection of elements enclosed in square brackets by a row vector, elements separated by spaces or commas. r = [7 8 9 10 11] Execute the above statement and return the following results: r = 7 8 9 10 MATLAB ...

Addition and subtraction of MATLAB matrix MATLAB matrix can have addition and subtraction operations, but the matrix of two operands must have the same number of rows and columns. Detailed examples Create a script file in MATLAB with the following code: a = [ 1 2 3 ; 4 5 6; 7 8 9];b = [ 7 5 6 ; 2 0 8; 5 7 1];c = a + bd = a - b Ru ...

1, Introduction Mathematical morphology operations can be divided into binary morphology and gray morphology. Gray morphology is extended from binary morphology. Mathematical morphology has two basic operations, namely corrosion and expansion, and corrosion and expansion form open operation and closed operation through combination. The open ope ...

1, Introduction Target tracking is a technology that uses the information about the target obtained by various types of sensors to estimate and predict the real state and future state of the target. Target tracking technology is widely used in military and civil fields. With the progress of electronic technology and computer technology, a vari ...
