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.

Next, the three YCbCr components are treated independently to a discrete cosine transform and quantization. This transforms each 8×8 pixel block into 64 discrete spatial frequencies.

Discrete Cosine Transform is an image compression technique and can be applied as a preprocessing method for classification problems. The reduction of the number of irrelevant pixels within the image ...

Real time imaging is essential for internet multimedia and modern satellite communications. Discrete Cosine Transform (DCT) is the core for image processing such as image compression and coding for ...
