一种提高无线实时低传输率下传输图像质量的方法(英文)

Effective Method to Improve Image Impression in Real-time Low-capability Wireless Channel

设计并实现了一种提高无线信道中传输基于MJPEG2000格式的实时图像质量的方法,图像的压缩与解压缩采用专用硬件ADV212实现,通过配置ADV212芯片自身的寄存器实现跳场,利用FPGA实现补场,在信道速率较低的情况下,能够有效地提高传输后图像显示的质量。

Aiming to improve the visual appearance without increasing the data rate, a real-time field skipping image transmission system, based MJPEG2000 format in wireless channel, is proposed, ADV212 is used for field skipping, image compression and decompression, field interpolation operated in FPGA. In channel capability limited conditions, a good performance can be got for the transmission image.
