As the title points out I need to find an average of the L, a, b values from a region of a photo. I can find out the values for a single pixel but these values vary to some degree in the region I am interested in. If this can not be done in photoshop but in an other program i'd be if you could show me how.
View 8 RepliesIs there a way to select a portion of an image and display the average RGB or Lab values of that area? Right now I can only see the values of selected individual pixels. Instead of manually adding up these values to get the average value which is quite tedious, can someone help me to a better option?

View 9 Replies View RelatedI'm trying to show, using the eyedropper tool, the actual values of pixels in an 8-bit grayscale image (Mode command confirms that's what's there). In the Info panel, the eyedropper tool displays percentages for every type of color information (K, CMYK), while the "8-bit" field remains blank.
View 9 Replies View RelatedI am comparing multiple scanned images and I need to find out if one image is darker than another. For example, if you print a document on 5 different printers and then scan those documents into photoshop 7, is there a way to quantitatively analyze how dark each document is. Can photoshop 7 tell you the average darkness of a selected area of an image? They will all be scanned on the same scanner so the only variable should be the printers. I need a numerical value for each, not just a visual comparison.
I am using Windows XP and photoshop 7.
I have 10 layers and I want to blend them such that the resultant flattened image represents the average colour. i.e. If layer 1 has a white pixel and layers 2-10 have black pixels the result will be 90% black.
View 9 Replies View RelatedI need to analyze an image and read the value of each pixel, exclude the highest and lowest values (perhaps anything less than 10,10,10 and greater than 245,245,245) , then average the remaining. I may need to do this on each channel of RGB.
I can almost get a result blurring the sample and then using a large brush with the info tool, but is there any other method more direct and all inclusive?
I have an attribute blocks and this att block has two tag values , is there a simple code for to change 1st tag values automaticly according to 2nd values ?
for example :
1st tag (50x50) - 2nd tag ( 100 ) ==> 50x50-100
if i enter 201 valuse to 2nd tag then 1 st tag has to change as 100x100
if i enter 501 valuse to 2nd tag then 1 st tag has to change as 150x510
I attached a jpg file for explain much better
Is there a way to have no layer value set for the description keys. I set all the layers, and now I realize I'd rather set this to no layers (boxes are all unchecked). I'd rather see no value under the layer column, but there doesn't seem like a way to set this.

View 2 Replies View RelatedWhat formula Civil3D uses to calculate the average slope of a surface?
The formula I am using is S = I*L/A
S = Average Slope
I = Contour Invertval
L = Length of Contours (ft)
A = Area of parcel (sq. ft)
I just had to do four parcel calcs and the percentage I find using the formula is always 1-3% lower than the percentage Civil3D spits out. I can't find anything about how Civil3D arrives at that number, it just appears. I assume that Civil3D is more accurate but I can't give that number to a client without knowing how the program arrived there.
I have been able to undertake this with other software and have desperately tried to find this same function in Civil 3D .
Is there a command that returns the average level of any particular surface within a specified area, for instance if we have a generated a large surface and then draw a square in the middle of the surface, can it calculate the average level within the square only?
I have 2 different surveys of the same area of ground. If i create a surface from each data set, can they be averaged into one suface? I know you can past them together, but how does it paste? the first one on the bottom and the second on time? I would like an average.
View 9 Replies View RelatedLet's say a have an image mask (see image shown below) where the white areas are the selection islands and then apply that to an image. What I want to do is get the average color for each selection island in that object. Just blurring gives you a gradient effect and if you blur too big, you just get a single color. That's not what I want.

I am trying to automate the average path command to apply the action to a field of discrete objects. In the end, I want each object to be avereaged into separate paths and not the entire group averaged as a single path. I have a very large set of objects and it doesn't make sense to select each object on an individual basis.
View 17 Replies View RelatedAny quick way of calculating average Parcel Area? I used to export to LandXML and do an area report in CSV. That doesn't seem to be working for me when I export out of C3D 2012.
The workaround I found was to select all the parcels in Prospector, copy to clip board, paste in excel, find and replace "_Sq. Ft._" with 0, then do the average.
We have to compute the average elevation along the front, sides and rear of a proposed building envelope to calculate the required set back.

I am trying to record an action to find the center of a polygon with the following commands
1. Select the object
2. Copy and Paste in Front
3. Select > Object > Direction Handles
4. Cmd+X (Cut); do not deselect
5. Object > Path > Average: choose both axes
6. View > Guides > Make Guides
All is good & well except that step 5 never gets recorded as an action step.
Is there a way to change an object's fill from a gradient to a solid color that is the average of that gradient? What I want to do is have a grid of squares, select them all and apply a colorful gradient to them as a whole, and then average each square's color so I end up with a pixelated look. Kind of like the mosaic filter in Photoshop, but in vector.
View 3 Replies View RelatedI have an acad document connected to some .shp files, which contain polygonal shapes with some meta-tags.
I want to achieve the following: draw a polygonal shape and select all the tangent areas (I already know how to do so)take a property of those areas and calculate an area-proportional [or: area weighted] average value (proportional to the partial area defined by the drawn polygonal shape). I tried to achieve this by splitting the objects and merging them again with defined splitting (area proportional) and merging (average) options. The problem is: splitting & merging doesn't work until I disconnect the data files (checking the objects out doesn't work) and even then I can't split the areas. And, more important: This doesn't create a weighted average and I don't even want to manipulate the objects! I just want to get one value out of all these steps.
I appended a screenshot of my file. E.g. I want to take the value 923.2 and multiply it with the corresponding area percentage it represents in the drawn shape. So the calculation would look something like 0.02*923.2 + 0.2*926 + 0.12*945,9 [...] until all the 100% are covered and I get one single representative value.

I wonder if anyone knows how to select(crop) the same region from two different pictures. Typically we have been doing this by using the selection tool and saving the selection which we can then load into the second picture. This works great except when we need to rotate the selection box at an angle.
If we do these and then try to crop, photoshop essentially puts a box around the selection that is straight which gives extra blank spots on the edges. When you crop using the crop tool, you can crop on an angle and photoshop straightens it out fine, but I don't know how to make it crop the exact same region of the second image then.

My application is I am creating a GIF movie in which that image will be moved around on the main image like a sprite / puppet.I need the section of the image that I place the mouse on to control movement to be invisible to the part of the photo that is being turned into a GIF/video.
