谢谢经验分享, 写的很详细了。
我刚刚又看了一下老外的经验 (看我以前的帖子http://www.astronomy.com.cn/bbs/thread-291584-1-1.html) ,自己试了一下,终于也发现了一些心得。
目前我的经验是AI处理下来图象会更加细腻,过两天会上图比较。
With 3X drizzle & wavelets in Registax6 I rarely employ anything but #1 & #2 sliders set at "full throttle" (ie, "100") with "Linked Wavelets" checked and Sharpening=0.12, applying De-noising carefully & observing the magnified image with the "Zoom View" window enabled - along with watching the "Histogram" set to "Log Scale".....I suggest you do some little trials yourself with all of this because you can easily open 2 Registax6 windows side-by-side on your screen and with AS!2 opened at the same time you just stack a couple of different stack-sizes/%'s and compare them at the same time in R6 with the same wavelets settings, although as said you might perhaps need a tad more de-noising for the smaller stack - but this isn't inevitable...the smaller stack might have much better SNR and not need any more de-noising whatsoever, despite possessing fewer frames in its' stack (you know what I mean about having two R6's + AS!2 open at the same time, don't try to have AS!2 actually processing as you're playing with the wavelets in R6 - AS!2 is a greedy little bu**#! with processors and likes to gobble up all the efforts of my 8 CPU's..!
(在R6中的处理, wavelet 锐化居然只处理layer 1跟layer2到100%, “linked” 设置)
现在的经验:这个处理的核心在 R6要用“linked” 设置,然后layer 1根layer 2 必须要自己设定denoise, 否则出来的图根本没法看,我之前就是受害者。
Regardless, getting back to AstraImage I usually apply an LR deconvolution at a greater C/W followed by ME at a significantly lesser C/W: this might mean as a rough example atm for Mars on a drizzled image perhaps 3@1.7 @ 1.7 in LR & 5 @ 1.2 in ME or somesuch.....LR is "sharp but vicious" in comparison to ME which has better noise outcomes - the number of iterations with LR is also important to regulate...what you have to be mindful of is not pushing any image in any processing software too far towards the "Ugly Zone"
给出了Astra Image 的卷积算法经验, LC卷积 (1.7 3次) 然后ME卷积 (1.2 5次)
实际处理上这个设定根据自己的图象要有所调整
LC卷积更激进所以噪声控制要差些,ME卷积噪声控制稍好
