摘要：

A novel interpolation method, using the type I discrete cosine transform (DCT-I), is introduced. The original definition of the DCT-I has been modified to suit this application. Three options for the modified DCT-I are proposed. © 1990, The Institution of Electrical Engineers. All rights reserved.
