你发的第一张看上去像HDR.
Photomatix我用了很多年了,从3.0版用到现在的5.0版.这个软件还是比较简单的,
tutorial网上到处都是,包括这个公司的官方网站都有.但是真正用得好的人还是不多.
很多做出来还是太假.
至于ps的blend,你有没有试过mask的时候用image->apply image?

Thanks for the feedback people.
I am gonna give photoshop->merge to HDR pro and manual blending another try,
with more patience and look into Photomatix.
No have not tried image->apply image.

你可以试下对mask进行image->apply image
这是一个挺有意思的技术,就是把原来的图像加到mask上,根据原始图像的亮度来确定
mask上的灰度.这样一来,效果就是根据照片本身把暗的地方自然的mask了,如果你对欠
暴那
张采用这个mask,那么他的高光部分(比如天空)就被保留下来了.同样,你把mask
invert一下,对过暴那张使用,就保留了阴影部分.这个技术提供了一个很好的mask的
starting point.当然这个和HDR是没有关系的.纯粹是手工blend.
我的建议是,如果你走HDR的话,就用photomatix吧,是最专业的HDR软件,几乎没有之一.

啊哈,找了好一会终于找到了一个tutorial讲解我前面提到的那个很cool的image->
apply image的技术。而且他处理的那张照片很像你贴的那张。
http://www.youtube.com/watch?v=zSpyvMdRSlY&list=TL3fg61BG01iZL1
虽然视频里他做的不是真正的hdr,blend的结果也不是特别realistic,但用的技术是
一样的,减低点强度就会得到很好的效果。

"Is this Canon patent application describing a mirrorless system camera with
an EVF and IBIS? We tend to believe it does.
Canon patent application US20180041705 refers clearly to image stabilisation
“in camera”. Moreover, as one reader noted, it looks like it will use a
current Canon mount, since it doesn’t have the short flange a mirrorless

the possibility: without an initial step of retrieving a set of images
based on texts and tags, the random surfer model and the image feature
method proposed by the paper is impractical---that's what the paper is
about.
my point is that while impressed by the model and method advertised by
the paper, you should know the key requirement for it to work---texts
and tags. however, this latter part---the restriction---tends to be
overlooked by people.

他建议我PHD论文搞Digital Image Forensics这个方向。
我感觉这个方向搞的人好像不是很多,另外应用领域似乎也不是很宽,不知道前景到底
如何?听导师的意思好像将来出去主要是去金融和政府机构。
我个人还是比较喜欢像MSFT或者GOOGLE这样的大型软件开发公司。
不知道这里有没有大牛给些建议和意见?

小弟准备1年后毕业,对工业界情况不太很了解。请
问各位朋友哪些公司在做Medical Imaging,
Computer Vision的东西。我该去申请哪些职位?
面试前应该准备哪些东西?
我的情况大致如下。国内还不错的学校cs本科,美
国50-100名master,现ph.d在读。RA几年做
Medical Imaging, Pattern Recognition,
Computer Vision,4篇一作文章,除了1
篇Transaction的期刊外,都是很一般的会
议,估计毕业时可能会有6篇一作。在美国一家小公
司混过1年的software engineer,公司太小,也
没长什么见识。没其他什么工作经验。编程上只熟悉
C++和Matlab。
当时选这个方向是比较喜欢做些有idea的东西。
有人说这个方向好找工作,有人说不好找。当时也没
想太多就上手做了,觉得还蛮有意思。所以倾向于做
些R&D的Coding,纯粹的Coding的工作也愿意接
受。
请教各位有经验的朋友,有哪些公司在做这个方向,
我的背景该去申请什么样的职位?

Thanks.
If Java's performance is really bad, I will have to use JNI to connect to
other tools. One example is to use JMagick - ImageMagick. But I really want a
pure Java solution if possible.
Java Image APIs confused me a lot. We have Java2D, JAI (Java Advanced Imaging
API), new ImageIO API and some old APIs in AWT package. Hope some experts can
give me hints so I can shortcut to the right direction.

来自主题: Java版 - 求助Java Image Tools or API
JAI is not a part of J2SE. Like other packages such as Java3D, they
provide a Sun implementation of some multimedia processing utilities.
If you care about platform-neutralism, you have to stick with J2SE,
which provides very limited support in image processing. ImageIO API
is new in J2SE1.4, you will have compatible problem if some of your clients
are still using 1.3 or lower. However, it looks like you are gonna process
image only on server end. So that's not a big deal. Just go ahead and

首先, 这取绝于你的目的到底是什么, 如果你就是想ZOOM IN/OUT而不对IMAGE进行修改,
那么800/600放到1024/768肯定有锯齿, 没有剧齿才是不正确的, 用AffineTransform就行
了,
如果你想修改IMAGE, 那么必然要CREATE一个SCALED的INSTANCE, 肯定会有一些计算, 会
花一些处理时间, 但也是正常的, JAVA一般在这些地方不会比C慢.

You don't, but on the other hand, if there's no security issue,

in windows, you can build the image, and its pdb file (which is used for

so you ship a small size of image to customer.
if it crashes, you have the pdb file in house for debugging.

Google用什么方法我不知道。但是分析搜索结果我猜用了下面几种技术:
1. reverse image search,搜同一个图的不同版本. 用SIFT, SURF等local feature。
我的那个软件就是做这个的。
2. search by visual similarity. 可以简单地想像成按color histogram搜。Google
可能有比color histogram牛得多的特征。
3. search by surrounding text。
4. 可能还有别的零散的技术,比如人脸识别对象识别等等,从图片中抽取关键字。考
虑到Google财大气粗,甚至有能力对人进行建模,检测到人以后可以对前景/背景分别
提取特征。最近应该也用上了neural network吧。但neural network给出的标签应该是
非常high-level的,对搜索帮助不会特别大。
最后把所有的结果rank一下,出来大概就是这个结果。Google确实是牛。我见过一眼负
责image search的那个老头,一脸苦B的样子,可能压力也非常大。
