Explain Reduction of the Resolution, Motion Estimation and Discrete Cosine Transform of MPEG compression process.

Explain Reduction of the Resolution, Motion Estimation and Discrete Cosine Transform of MPEG compression process.

Reduction of the Resolution:

1. Performs the conversion of RGB-color space into YUV color components.

2. The chrominance components U and V can be reduced to half of the pixels in the horizontal direction.

Motion Estimation:

1. Two successive video frames often have small differences.

2. MPEG standard has a standard to reduce this temporal redundancy.

Discrete Cosine Transform:

1. It is similar to Fast Fourier Transform.

2. The frame blocks of size 8x8 or 16x16 pixels are represented as frequency components.

3. This transforms into frequency domain by implementing standard formula.
