Hyperspectral images have considerable spectral information, and lots of spectral similarity measures have been developed for hyperspectral image analysis. However, little research has been done on the effectiveness of the spectral similarity measures. This paper introduced three spectral discriminatory measures, the spectral discriminatory probability, the discriminatory power and the spectral discriminatory...
In MPEG-2 to MPEG-4 Simple Profile (SP) transcoder based on the discrete cosine transform (DCT) domain, data conversion from the field DCT to frame DCT must be implemented. We proposed a low-complexity conversion method based on the DCT domain, which does not need performing inverse DCT and DCT. This method exploits the relationship between the filed DCT and the frame DCT on the transform domain to...
