oddly, pointing at other watermarks in said folder (we have different colours/sizes for different outputs) the error goes/those watermarks show - but checking out our standard one, it still has its alpha and seems fine.
I don't know if it is connected issue but for me sometimes happens that ENS doesn't see some textures but it happens on start up of ENScape.. The textures oddly are there.. I searched for them on my PC.. Usually in temp folder.. pointing again to them doesn't change a thing.. So it looks like very similar issue. Closing sKetchup and opening model again solves problem. Somehow ENS seems to loose the track of texture if there is too much time between turning on sKetchup and ENScape window..?
In the below picture we are setting up 2x Projection screens (colorbars), some black drape, a stage and some white scenic panels (white boxes). I have a client that is requesting that we use projection on the scenic elements to create a projection mapping look. Is there a way to represent this in SketchUp?
I have a model that has the same white box scenic component used in various forms and I would like to be able to apply a picture to it to see what the potential projection would look like. Is there a way to apply the one jpeg texture (in this case the blue shooting stars) stretched across multiple components?
Unfortunately, You can apply textures to different components but it will not map correctly. You will want to apply textures to the face but as they are all the same component, you still wont get the results you are wanting.
Option 2 - You can select one the textured tiles and then change the mapping via the Texture > Position feature. After you have remapped the texture on the tile, you can sample the new mapping from the tile and apply it to the other tiles.
robertjuch, thank you for this option. This works well. The only thing is I have to be mindful of the grouping of the tiles. Sometimes I have multiple clusters that I want to apply different textures to.
After applying textures, you can group them in separated groups Triple click on each box (in my case double click on each face) will select all edges and surfaces on each element and custom keyboard shortcut for grouping will help you make it faster.
A quick warning, features like these in H&E slides are more often a result of sample preparation, staining, and tissue variance than anything of clinical relevance. The two images above do not look like they were captured from two differing regions of the same tissue slice, but two differently prepared tissue slices.
Haralick features: I recommend looking up the old paper, that is where I started. I believe it has been linked on the forum in other posts discussing the features. They can be calculated constrained to objects - so the easiest way to look at the features within nuclei would be to use no Cell expansion. That way, when you calculate the Haralick features, they are constrained to the nucleus. Or use the Nucleus option when selecting the ROI. Unless you have a very high resolution scan with no JPEG compression, there may not be enough information in a single nucleus to get good measurements, but you can certainly try. It might be interesting!
Haralick features and other Add intensity features can also be used in areas around objects using the circular or square ROI tile option. That tends to include some background information about the surroundings and has been more stable in my experience.
There are a few ImageJ measurements available through scripting, since much of the original ImageJ is accessible within QuPath. Alternatively, you can point to a Fiji application through the Preferences, and run a macro across tiles of your WSI. There are a few posts on the ImageJ Macro Runner that have more information if you are interested in something that Fiji can provide.
I still do not understand what Haralick distance means or how I know what value to use. Also, I have searched on line but cannot find a simple description of what the different features mean. When would I be interested in Contrast and when would I be interested in Correlation (for example).?
From your example image, the standard deviation, min and max measures for haematoxylin intensity in the nucleus (all available by default from cell detection), may be used to distinguish the textured vs normal nuclei.
In my (non-representative) test using your example image, the object classifier returned Eosin std dev and Haematoxylin std dev as some of the few top variable importance. Eosin probably came up on top because its staining intensity is clearly higher in the left image than the right.

Alternatively, there are even fairly recent papers published using/about the features: Haralick texture features from apparent diffusion coefficient (ADC) MRI images depend on imaging and pre-processing parameters Scientific Reports
Because I need a material with same resolution for many objects of different sizes.
I also know real size of photo that I use as a material texture. I know that 1024 pixels are like 1024 mm +/-.
Doing it my way I import texture just once, and if I use it for multiple objects (sometimes 50 or more) - texture has same scale (matches with other objects), no matter if object has 10mm or 3 meters.
I use a simple template, every now and then when I choose an object, click on Ctrl B to choose a texture, click on the texture, it suddenly crashes. and It happens quite a lot. Happened when I had the free version, happens now that Im paying for it.
You did send in a bugsplat in November, and that looks like you were editing materials at the time. This new crash you had may be the same kind, and for that one we do have a fix that will be in a future update.
