Resource Overview
This graphical user interface enables digital watermarking operations on images through DWT/IDWT transformations. Users can batch process image folders with single-click functionality, embedding watermarks in frequency-domain images while automatically calculating PSNR and MSE metrics for extraction quality assessment.
Detailed Documentation
This graphical user interface allows you to select any image and process it by adding digital watermarks. With simple button clicks, you can execute the code across entire folders sequentially. The system embeds images within other frequency-domain images using Discrete Wavelet Transform (DWT) for embedding and Inverse Discrete Wavelet Transform (IDWT) for extraction processes. The implementation includes automatic calculation of Peak Signal-to-Noise Ratio (PSNR) and Mean Squared Error (MSE) metrics to evaluate the effectiveness of the watermark extraction procedure. The core algorithm operates by decomposing images into wavelet coefficients, modifying specific frequency bands for watermark insertion, and reconstructing images while maintaining visual quality.
