MATLAB code of Image Enhancement using Brightness Preserving bi-Histogram Equalization

Hello, Friends today posting one project in the field of image processing. The title of the code is Image Enhancement using Brightness Preserving bi-Histogram Equalization. The Brightness preserving bi histogram equalization firstly decomposes an input image into two sub-images based on the mean of the input image. One of the sub-image is set of samples less than or equal to the mean whereas the other one is the set of samples greater than the mean. Then the BBHE equalizes the sub-images independently based on their respective histograms with the constraint that the samples in the formal set are mapped into the range from the minimum gray level to the input mean and the samples in the latter set are mapped into the range from the mean to the maximum gray level.

MATLAB code of RSA Encryption and Decryption of Text

Hello, guys today I would like to post one more project in the field of information security. The title of the project is Encryption and Decryption of text using RSA (Rivest-Shamir-Adleman). RSA (Rivest-Shamir-Adleman) is an Asymmetric encryption technique that uses two different keys as public and private keys to perform the encryption and decryption. With RSA, you can encrypt sensitive information with a public key and a matching private key is used to decrypt the encrypted message. Asymmetric encryption is mostly used when there are 2 different endpoints are involved such as VPN client and server, SSH, etc.
