Technical Terms DCT (Discrete Cosine Transform): A mathematical technique that converts spatial pixel data into frequency components, crucial for energy compaction in image and video compression.

Today, image data is part of the development of big data whose volume, variety, and velocity are huge. The watermarking process is one of the simplest methods but effective and popular methods to ...

Fortunately, there are several methods of image compression available today. These fall into two general categories: lossless and lossy image compression. The JPEG process is a widely used form of ...
