A New Intra-Frame Coding Algorithm for Image Compression
Chenggang Duan, Zhihang Zheng, Xiao-Wen Yang, Xin-Biao Hui, Zhou Zhu · 1996
In this paper, a new Intra-frame coding algorithm is proposed for image compression. Due to the small block size in transform coding, the DCT coefficients at the same frequency between the adjacent blocks have strong correlation with each other. For more effective coding, the interblock correlation is decreased. At last, this algorithm is compared with intra-frame coding method in MPEG.
