Photoshop :: Filtering Selection By Cluster Size
Feb 14, 2013
I have an artwork that eventually be used for laser cutting. The artwork was created by Illustrator. I would like to identify very small cuts so I can eliminate them. My thinking is that it will be easier to do the analysis after rasterizing the artwork and use Photoshop for the job.I was thinking to select by color the color that marks holes (white). This will yield a selection of multiple regions (clusters). Now I would like to filter out (or in) all the clusters that meet some size criteria (contains less than X number of pixels, or that the perimeter size is more or less a value) in order to identify the small clusters.

I was *so* hoping that we'd finally be able to filter (or create a Smart Collection) based upon file size.
There are many reasons why this would be useful but the thing that trips me up every once in a while is that I'll forget to flatten my layers in Photoshop and the resulting tiff could be over 500 MB! Everyone once in a while I'll manually find the large files, flatten the layers, then re-import them into LR - in the specific case I mentioned the file was reduced to 17MB.

I'm having a problem making paper size filtering 'stick'.
For years I've configured PC3 and their associated PMP files for each of our printers and plotters. As a part of the configuration, I filter out all the paper sizes we don't use. Once the PC3 and PMP files are configured, they're copied to all the local PC's. I've never had a problem with this, until now.
On the PC where the PC3 file is configured, the filtering is correct. On any other PC, various paper sizes are added. For instance, I'll filter out all paper sizes on printer "X" except for 8.5x11 and 11x17. On a similar PC, the paper sizes "16k 197x273mm" and "8k 273x394mm" are added.
If I point the PC's to a location on our network where the PC3 and PMP files are stored, I get the same results.
We have two OS's here - Win7 Pro and XP Pro. All OS's are kept up-to-date. All the Win7 PC's use the same version of the HP Universal Print Driver. All the XP PC's use the same version of the printer specific drivers.

I have a spider animated in CAT. I need to create 100’s of them now emanating from a hole and spreading out across the surface in all directions. What would be the best way to achieve that? It’s like a flock of birds but they all need to be crawling and stick to the ground or terrain.

I'm having a deformation problem with clusters. Basically, the clusters are deforming the object which they are parented to. I've checked "relative" for each cluster under the attribute editor.
Regarding hierarchies, the above is the last iteration I have tried. Before that, I tried parenting the clusters to curves first then parenting the curves to a master control. The object was also parented to the master control.
I've tried maya default of grouping individual clusters first then parenting them to either the object or the master control, but the same results are achieved.
Please see the video below.
At one point the clusters were behaving as required, but I can't reproduce the results. I was going to animate the CVs, but parenting the curve to geometry or control presents problems of its own.

Like in title, when I apply blendshapes to mesh with skincluster, I cannot paint weights anymore. It sais:
"maya expected a skin cluster deformer or a deformed shape. Found *.*blends instead".
I tried both, applying skin cluster first and blends first. I know for input graph (there are no issue).
There was no such problem with Maya 2011. I use Setup machine for the rig.

I have cropped a person from a photo and moved the image into another photo. I now want to increase the size of the "person" I moved while keeping the background the same. I'm sure it's a simple procedure but after a couple of hours of frustration.

I'm trying to use the quick selection tool to take part of an image out and combine it with another but when i click to make the first selection a "Could not use the Quick Selection because the result would be too big." message shows up. I havent even made a selection so how would it determine if it's too big? I just don't get it.

I am making selections of models off of a white background. I use the quick select tool and refine to make a clean selection. I go in and use the clone tool to remove the "halo" that is still there to make a super clean selection with no light bleed on the model. I put a black layer underneath to make sure that I got all of the remnants. I save the selection and turn it into a channel. I apply the layer mask and everything looks good. I flatten the image and put it on a white background (this is the desired form of delivery for client) Image saved and closed. When reopened, I make a selection using the channel and there is a distinct halo effect still present. I have tried making the selection and going over it a couple times with the brush at 100% and it works a little bit, but not entirely. I have already spent a lot of time going through cloning things out so it looks good, delivering the images, then they are sent back because of the halo.

I have a question that relates to a digital image that is of an old original B/W photograph.
The image is of an old, plain page of a book found by Police some 65 years ago, in it's orginal form the police had noticed what appeared to be indentations or very feint writing on this page and used graphite powder to highlight their findings and then went over the highlighted areas with what appears to be an early felt tip pen. This was then photographed and an image produced.
The intial image itself is quite small about 400 X 400 px.
It shows 5 lines of hand written characters with additional hand drawn lines.
Here is an example of a close up of the 'sharp end' of the two crossed lines in the centre of the page:
Here is that image reversed:
When I examined the image in more detail I noticed that the actual characters and lines were not simply black markings but in fact had various shades ranging from grey through to black within them.
I turned the image negative and it showed up what appeared to be smaller letters and numbers behind the initial blackened markings and lines. I have done some basic filtering and have managed to improve on the appearance but only a little.
The questions I have are these:
1. Are these real markings or are they some kind of digital noise? Most of the letters and lines on this page show signs of letters and words beneath the drawn over markings. (I have done a lot of research about micrography and such miniature writing does and did exist at the time and in fact has been around for 4000 years or more)
2. Is it possible for me to 'strip away' further layers of lighter coloured pixels to sharpen the markings that appear to lie beneath the overdrawn characters and lines?
3. This being so, what steps or processes can be used to achieve better clarity and hopefully a larger image.
I hope I got that right and it makes at least some sort of sense

I work on lots of images and sometimes when I get them they new feature 'layer filtering' is set to on, and sometimes it's off. I want it to always be off but can't find out if that's possible. I continually have to disable it manually when it hides layers I need and it's getting frustrating.

How do you see the size of a selection (in pixels?). In Photoshop this would be in the info dialogue window. I'm not finding the equivalent in GIMP (2.6).

I'm a former Photoshop user. The reason I no longer use it is because of a silly misunderstanding with the NSA and MI6. But hey, that's the past and I'm a believer in moving on.
Anyway, my first inquiry here is a simple one having to do with selection. When I used PS I would at times use the wand selector and then open a new file which already had the dimensions of the selection. Thing is, when I select something in Gimp and open up the new file it still has the same size as the main image from which an area was selected, i.e., if the main image was 500x500 and I selected something 100x100 the copy was still 500x500.
And I can assure you it has nothing to do with remote viewing and foreign embassies.

I have a need to repeatedly 'copy' an area of a certain size (say X by Y) from a number of images.
I can set the size, by eye, using the rectangular selection tool and then simply move that to each area on the image I wish to copy - no problem.
But I want to do the same size from a number of different images (and will be doing this over a number of different sessions/days etc.)

so, first off, am using photoshop CC on windows 8,
here's my question: they improved the layer filtering option to photoshop cc which is great, but it's activated by ctrl+double clicking, since i do vectors in photoshop i use ctrl+clicking to select shapes and move points, so when am working on my vectors and moving fast, i always activate and deactivate the layer filtering option, which is very annoying, i cant work as fast as i did in cs6, any way to change the shortcut or activation method for this option?
what i have notices so far is that when you ctrl+doubleclick on the path of a shape is switches filters that layer. so then i have to turn of the layer filtering thing to find my other laye
plase plase plase, how can i deactivate completelly this option, i have a lot of work to do and this is annoying me sooooo much.

I have to use the Image > Canvas Size option to resize the size of my canvas to a wanted size. However this means a lot of trial and error to get the canvas size the same size of my current selection. Is there a quick function that would resize the canvas size to my current selection?

Previously, every time I selected an object (line, shape, text...etc) the program gave me an option to rotate or change the size of the object by creating a square with four points around the selection. I could then click and drag a corner of my selection thus rotating it and/or changing it's size.
Now, for some reason, this feature has been disabled and the only way I can manipulate the object is by physically typing in a new percentage for it's size or by going to the Object>Transform Menu. Did I accidentally hit a key command that disables this feature?

I have two pictures and I try to copy a small part of one picture to the other.I did a rectangular selection of 2 cm square of the first picture and copied it but when I pasted it in the other picture the selection was now 4.68 cm square.
I suspect that's because the two pictures have not the same resolution. How can I keep the size of the selection from two pictures of different resolution?
