Comparative study of transform coding for super high definition images
Junji Suzuki, M. Nomura, Shintaro Ono · International Conference on Acoustics, Speech, and Signal Processing · 2002
The characteristics of super-high-definition images with resolutions of up to 4096*2880 pixels are examined by autocorrelation measurement, and these values are compared with an image having spatial resolution comparable to existing TV. In order to obtain the basic characteristics of such images and coding performance, a simulation system including a digital camera with 4096*4096 pixels and a frame memory and monitor system with 2048*2048 pixels is set up. Two different DCT (discrete cosine transform) coding schemes, DCT with adaptive bit allocation and DCT with variable-length coding, are applied to evaluate the performance of transform coding on super-high-definition images.>
