昨天被虫子咬醒

July 19, 2008

年久失修,凉席生虫子了,虫子好生厉害,凌晨4点把泡泡咬醒,七咬七个包,还想嫁货给蚊子,亏泡泡借IPOD灯光侦察蚊帐没发现蚊子踪迹,证明了蚊子的清白。会不会觉得我很无聊~嘿嘿

一大早起来晒被子晒席子晒枕头,下午突降暴雨,看来只能睡木板了。

还有些发现,被咬醒了睡不着,继续我的COLOR空想。想起昨天扫的篇ANNUAL REV NEURO,COLOR PERCEPTION。
原来HVS有3条parallel channels:luminance, red-green,blue-yellow pathway.在retinal circuit的时候已经把颜色信息分类初加工了,这个和HSV COLOR SPACE有些像,但HUE并没有完全提取出来,倒是有些奇怪luminance怎么这么快就被提取了,那说明要retinal circuitry还是很有研究价值的,至少很bottom-up,…
有时间了去折腾一下color context,information redundency of color
