1. The mapping function could be strongly influenced by only a few extreme (low or high) pixel values, which may not be representative of the image content.

2. This can be avoided to large extent by "saturating" a fixed percentage (s-low, s-high) of pixels at the upper and lower ends of the target intensity range.

3. Predefined quantiles (s-low and s-high) of image pixels are "saturated", i.e., mapped to the extreme values of the target range. ) The intermediate values are mapped linearly to the interval [a-min, a-max].


最後要談到思想,在這裡,我發現了它才是我的真正屬性,只有思想與我密不可分。

有我,我存在,這是毋庸置疑的,可是,我能存在多久呢?我思想多久,就存在多久,換言之,只有當我思想時才存在。因為如果我完全停止了思想,則我或許就會完全不存在了。

我現在既然一律不承認任何虛妄的事物,因此,嚴格說來,我只是一個思想物(thinking thing),也就是說,我是一個心靈( mind),一個靈魂( soul ) ,或是一個理解(understanding),一個理性(reason ) ,這些名詞的意義都是我以前所不知道的。

無論如何,我是一個真實的東西,而且是實際存在的,可是,我到底是什麼勿東西」呢?我已經答覆過了:我是一個思想的東西。
