color image watermarking using DCT and DWT

详 情 说 明

In the given text, the topic discussed is color image watermarking using Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT). This technique involves embedding an invisible watermark into a color image to protect its authenticity and integrity. By utilizing the properties of DCT and DWT, the watermark can be inserted in a robust and imperceptible manner. This process allows for the detection and verification of the watermark, ensuring the security and ownership of the image.
