DSP_JPEG2000_001.pdf
- 本文介绍了JPEG2000的静态图像压缩技术在TI TMS320DM642 DSP上的实现过程;对压缩技术核心小波算法结构进行改进,对硬件特点的程序结构、具体代码及总线读写等方面的改进作了详细描述.改进后的软件系统,对于1 024×768像素大小的图像、数据存储空间仅需6 KB,使得在资源有限的DSP芯片上能够运行JPEG2000图像压缩技术;编码速度相对于未改进的提高了l2~ 2O倍,可迭到3帧/s;压缩比为O.5 bit/p时,峰值信噪比可达到3O.-This paper introduce
JPEG2000_006.pdf
- 本文提出了一种基于提升算法的高效JPEG2000二维离散小波变换(2D—DWT)~ 结构,将边界延拓内嵌于离散小波变换过程中,减少了所需的内存空间和功耗。采用W 扫描输入方式和行列并行处理结构,加快了变换速度,大大提高了小波变换的效率。整个二维离散小波变换结构已经通过FPGA硬件仿真验证。-This paper presents a highly efficient algorithm based on lifting JPEG2000 two-dimensional discrete wave
