clarity是調整局部的對比度的,運作模式和銳化類似,我之前有篇系統講銳化的帖
子裡提到過
所謂局部,就是有色階差別的地方,比如左邊深一點,右邊淺一點
但是不一定是一刀兩斷,有條硬的邊界,通常是有個範圍來逐步過渡的,這個範圍PS裡
一般用一個叫“半徑”的參數來表示,單位是像素
加大clarity,就是搜尋這樣的地方,然後把兩邊對比增大,深的更深,淺得更淺
看上去便更加“分明”了
其實這“邊界上深的更深,淺的更淺”也就是銳化,不過銳化是在半徑約等於邊界範圍
裡做,比方一兩個像素
clarity是在半徑遠大於這個邊界的範圍裡,比如幾十像素寬的邊界,便在兩側幾百像素
的半徑裡調整
usm銳化裡,如果把半徑設為很大的值,那麼也能得到類似clarity的效果
反之把clarity往負方向拉,便是抹平這個邊界的差異,深色變淺,淺色變深,效果便是
更朦朧一點

最近拿到一些tumor, vessel图像,想把这些图像做成1000x1000像素大小,然后根据每
个点的颜色做成一个1000x1000的double矩阵
我是做cancer model的,没做过图像处理……
请问有什么solution么

The biggest problem with inexpensive Android smartphones in most markets
comes in when you observe the quality of the hardware and software being
deployed. While it is not expected that a device retailing for $200 off
contract be comparable to a flagship phone like the HTC One M8, that doesn’
t mean they should be pitted against hardware that’s several years old like
the HTC G1. Google announced an initiative to address this issue in
emerging markets throughout the world during Google I/O, and the first of
these smartphones with the Android One brand is now available in India.
Having an Android One phone is, essentially, having a guarantee that you
have a device capable of getting regular software updates from Google. This
is a two-stage problem in many emerging markets, as you require both
software capable of receiving the updates and the financial means to pay for
the often hefty download associated with the update.
The Micromax Canvas A1 with Android One is an Android 4.4.4-based smartphone
with a 4.5-inch 480 x 854 display and a 1700mAh battery. While nothing
earth-shattering, at $105 it’s not a bad little phone. To help with the
data struggles, if you are using Airtel as your carrier Google will foot the
bill for the first six months as well as the first 200MB of apps you
install.
This has been an impressive initiative from the beginning, and it is clear
that Google has no thoughts about slowing down. Alongside this impressive
announcement, Google’s Sundar Pichai announced partnerships with Acer,
Alcatel Onetouch, ASUS, HTC, Intex, Lava, Lenovo, Panasonic, and Xolo to
bring Android One hardware to Indonesia, the Philippines, and South Asia by
the end of the year.
Google’s plan to connect the next five billion people seems well on its way
, and with the next version of Android right around the corner it looks like
the claim that these phones will get Nexus-style updates will be tested
very soon.

没用过ps里的,用lightroom的~
好多人使劲的abuse这个功能啊~
人像会变别扭~=0=

you can use a software called Matlab. the functions involved are very simple
and direct.
Let me know if you need further help.

it should be simple to read pixels' info into a matrix.
I searched the help file, it came out 200 results....
could you tell me which function should be used? very thanks.

simple

我好久没有升级了,还在用老古董ps 7.0
这个clarity听起来好像就是一个high pass filter,然后加在原图上overlay

such as function: 'imread'
the input is the file name, the output the the pixel inforamtion matrix.
for example:
I=imread('C:\mypics\image_1.png');

你用camera raw的话会有,PS里是没有。

用什么机器拿到的图像?1000×1000很高了。通常我们都做512就不得了了,如果多就
分解开,否
则处理起来很麻烦。
