这次应邀与才华横溢的插画家尧立女士合作，携手推出音画册《九色鹿》（中国少年儿童出版社出版），用视听融合的方式把九色鹿的故事传递给孩子和家长们，我感到极其荣幸。因为我觉得敦煌留给世界的不只是古老的壁画，还有信念，对慈悲的信念，对善良的信念，对大自然的爱与对和平的向往。正是这样的信念，让中华民族长久以来在世界上受人尊敬，也正是这样的文化遗产让世界友人向往中国、向往敦煌，聆听中华文明的故事。，详情可参考一键获取谷歌浏览器下载
Another way to approach dithering is to analyse the input image in order to make informed decisions about how best to perturb pixel values prior to quantisation. Error-diffusion dithering does this by sequentially taking the quantisation error for the current pixel (the difference between the input value and the quantised value) and distributing it to surrounding pixels in variable proportions according to a diffusion kernel . The result is that input pixel values are perturbed just enough to compensate for the error introduced by previous pixels.
