Is it possible to create kernel which will blur the parts of image which are sharp and also will sharpen the areas which are blur?

For instance in this image I have marked regions with text which should be sharpen more (red frame) and areas which should be sharpen less (orange regions). The bottom ...

Ok, this is why I was confused because I expected IM layers works similarly like Photoshop, where all layers stay in memory and do not merge them-self or remove them-self until user does it.

It is more light than dark. If I applied levels, the result is what you see. The yellow routes were selected not rivers

Maybe I should just try to create my ...

Once you do -evaluate-sequence once, you no longer have the previous images.

That is important information.
Could someone add this to the description?

Looks like tomorrow I was too tired so I did not read snibgo's post completly or I don't remember what I read. So now again reading... Snibgo you said, you measured 0.12s with

I am back to learn how to work with multiple layers. Just tried examples from page 8 and they do not work for me suddenly. I have saved the batch files when I did this years ago but they do not work. For me. The colors in -fill are correct as I checked it again.

Now this command:

convert map.png ...

Sorry that was wrong assumption == non-sense. So another idea.

If the white mask of the water would contain empty places, would you perform compare (slow) or could you perform a search of rectangle inside the white area? Let's have this mask as a result of some search of water surface. Let's ...

Snigo, Well done. I found it is needed to add one more mask which is a bit darker. Down there at the river in the bottom there are ship-travel paths which are darker.

Now I have found your article Searching an image http://im.snibgo.com/srchimg.htm which is great because you write the scripts using Windows shell syntax. It will take some time to read it but now I am at this point:

"The script srchImg.bat does two or more searches. The first resizes the images ...

Please if you know more techniques for searching sub-images VERY fast gimme some examples. I need to work with big images like high resolution image of map to find the sub image. This could take long so more examples with better performence are welcome. Also the problem of this techniq is that is ...

I have written this batch file for Windows:


@ECHO OFF
cls
ECHO ON
REM To reduce processing time 18x I scale the image

Yes it works. I am waiting for result coz it takes long... 55 seconds for 1024x768px

This way it seems too much complicated. If I want to find blue rectangles on the map here:

I used output image too but that is strage. It still gave that error. That is not error of IM but of the system file not found
