The Discrete Cosine Transform (DCT) along with frame diierencing, normal-ization and quantization are used in a variety of video compression techniques that are designed for image sequences. These techniques produce lower quality image sequences suuering from artifacts such as blocking, frame repeats, blurring, image persistence and edge business. The artifacts tend to increase with higher spatial-temporal information content in the image sequence. Bad image frames such as those suuering from… CONTINUE READING
