Lowest Band Coding Method in Band Division Coding

摘要

The present invention relates to a low-band image coding method in a band division encoding method. The method of the present invention relates to a low-band image when a size of a low-band image is not a multiple of 8 × 8 blocks. By setting the maximum size that can be encoded by the block discrete cosine transform, the discrete cosine transform can be performed, and the remainder can be encoded by the differential PCM to perform high rate encoding.
