The feature selection process can be considered a problem of global combinatorial optimization in machine learning, which reduces the number of features, removes irrelevant, noisy and redundant data, and results in an acceptable classification accuracy. Feature selection is of great importance in pattern classification, medical data processing, machine learning, and data mining applications. Therefore, a good feature selection method based on the number of features investigated for sample classification is needed in order to speed up the processing rate, predictive accuracy, and to avoid incomprehensibility. In this project, particle swarm optimization (PSO) is used to implement a feature selection, and support vector machines (SVMs) with the one-versus-rest method serve as a fitness function of PSO for the classification problem.

MATLAB code of Image compression and Encryption using Fractal and DES respectively.
Hello, Guys posting a new project in the field of image compression and encryption. The title of the project is Image compression and Encryption using fractal and DES respectively. The ides behind this project is first input uncompressed image is compressed using a fractal compression method and then it is encrypted using the DES encryption algorithm. At the receiver side first, it is decrypted using DES decryption and then it is decompressed using fractal. The MATLAB implementation of the project is shown in the following YouTube video. just have a look.

Text Steganography by LSB substitution using genetic optimal key permutation MATLAB code
Hello, friends today I would like to post one project in the field of information security. The title of the project is Text Steganography by LSB substitution using genetic optimal key permutation. Data hiding techniques embed important data into multimedia data such as images, videos, or sounds. Digital images are considered good cover carriers because of their insensitivity to the human visual system. Watermarking and steganography are two major branches of information hiding technology. Each has its own specific characteristics. The MATLAB implementation of the project is shown in the following Youtube video. Just have a look.

Image Steganography by LSB substitution using genetic optimal key permutation MATLAB code
The popularity of the Internet offers great convenience to the transmission of a large amount of data over networks. Some of them may be secret information which is a candidate to unauthorized access. In order to keep the unauthorized user away, a variety of techniques have been proposed, data encryption and data hiding are two main methods in data security. Data encryption uses a certain algorithm to transform data into ciphertext only the user that has keys can decrypt the secret data from the ciphertexts. For any unauthorized user who does not have a key, the ciphertext will look like nothing but streams of meaningless code. Although data encryption is a good way to secure data, it still has some weaknesses. The appearance of ciphertexts would give unauthorized users an impulse to recover them. Moreover, the unauthorized users might even simply destroy the ciphertext out of range when they have trouble recovering them so that the legal receivers cannot get the data in time. That is the reason why data hiding has been researched recently.
