In order to measure the dispersion coefficient of air refractive index and other transparent material rapidly and accurately, this paper studies the dispersion coefficient measurement system based on CCD imaging technology. On the basis of consideration of the air refractive index impacting on the measurement accuracy of dispersion coefficient by using the(More)
On aviation mapping, compression image maybe not decode because of wireless transmission interference. UEP (unequal error protection) scheme is put forward about layer and block structure of JPEG2000 image compression method, and realizes three degrees UEP of data block, data header, image data via various degrees correction-coding under the condition of(More)
