例句与用法
- Discrete cosine transform ( dct ) is one of common transform encoding technique in common use of image compression . because such advantages as relatively matured theory , arithmetic and hardware ; ease to move relativity ; fit human vision system ; less calculation ( not include plural calculation ) : ease to realize and so on , dct compression is widely used
离散余弦变换( dct )是图像压缩中经常用到的正交变换编码技术，由于理论、算法和硬件相对成熟，去相关性好，适应人眼的视觉特性，计算量不大(没有复数计算) ，易于实现等优点， dct压缩编码的应用非常广泛。
