SUN Hang, FENG Qiang, HAN Hong-xia. Infrared Sequence Image Dynamic Compression Display Based on FPGA[J]. , 2011,26(4): 551-554 DOI: 10.3788/YJYXS20112604.0551.
When compressing image of high bit-wide infrared cameras to 8-bit analog image to display
it exists that image lost the most details
this paper put forward a new algorithm that use the Gauss filter to make the image still to keep the infrared image detail information after compression. The paper introduced the method how to make algorithm to be realized on FPGA hardware
and make an experiment that 12 bit camera image is compressed to 8 bit analog display on real-time. The experimental results show that the system can keep the detail information perfectly under the condition of restrain noise
and can change 12 bit-wide 320240 surface array of infrared cameras into analog video under preserving details.
