The esthetic appeal of Yi’an Style is manifested in the sincere sentiment, lofty savors, implicit style, happy rhythm and the novel sentence, which forms the unification of the content and form.

This article analyses its manifestation from three aspects: nationalism, fantasy and frankness.

His straightforwardness,his great ideology and emotional extroversion shaped his arrogance,elegance and frankness,demonstrating the marvel and charm of his personality.

It is due to his forthright and sincere aesthetic pursuit in this period.

And for the encoder,two weighting methods of the rate-distortion slope are proposed.

In order to implement the real-time code-stream truncation during the Tier1 coding in JPEG2000,the rest rate-distortion information of an image tile is combined with the rate-distortion slope of the current coding pass to determine the truncation of the current coding pass,thus effectively guaranteeing the real-time coding and decoding of the JPEG2000 system.

The UTCQ superset indices can be represented by coefficient bit plane, Rate-distortion optimized embedding code allocates available coefficient bits with decreasing R-D slope, so the first coding bits are ones that have the steepest R-D slope.
