摘要
采用FPGA+ADV212来实现JPEG2000的图像压缩技术,不仅提高了压缩效率,同时也高效的发挥了FPGA的并行处理能力。由于2.6um到3.2um波段的短波红外的响应输出范围较窄,采用5/3压缩算法,避免了此波段的短波红外受压缩本身所产生的大量噪声影响。此系统能够灵活的配置压缩比、压缩深度等图像压缩的相关参数。最终系统不仅具有体积小、功耗低的特点,而且能够提供高质量的可复原的压缩图像。
By using the JPEG2000 image compression technology with the FPGA+ADV212, not only improved the compression efficiency, at the same time also brought into playing a parallel processing ability of the FPGA. Since 2.6um to 3.2um band of short-wave infrared response output range is narrow, the 5/3 when the compression algorithm, avoids the bands of shortwave infrared affected by compression itself produces a lot of noise. Since the range of output response in 2.6um to 3.2um band is narrow, by using the 5/3 compression algorithm, avoid this band of short-wave infrared to produce a lot of noise by itself. This system can be flexible configuration in the compression ratio, compression depth as well as the related parameters in the image compression. Finally the system not only has the characteristics of small volume, low power consumption, and also can provide high quality of compressed image which can be recovered.
