Code for DCT_SNN, an input encoding scheme for SNNs using DCT

CIS 4110 Comparison of Image Steganography Techniques (DCT vs LSB)

Block Discrete Cosine Transform (block DCT) using TensorFlow

Implementation and Performance Analysis of DCT Steganography Algorithm. Tests found that it has excellent imperceptibility (PSNR all above 40). When encountering noised images, the error rate of watermark extraction is low, indicating certain robustness. By introducing the scaling factor, the best embedding effect can be obtained for the specifi…

This project focuses on detecting a specific form of image forgery known as a copy-move attack, in which a portion of an image is copied and pasted elsewhere.

Steganography techniques to encode secret messages in various mediums.

Uses LSB, DCT, and DWT to insert pieces of text into images.

Twitch and other streaming platforms rely on advanced video compression this project showcases a simplified version of those principles (DCT, quantization, motion estimation), but is not connected to Twitch itself.
