Each of these shows the 2 input images and 1 output image by following methods

Hi,

I would appreciate if someone can please let me know how to stitch or merge 2 images together based of a reference point or region on each images so that a new image is joined by overlapping or superimposing point or region from each image. This is something like page 10-12 of below document ...

Thanks for help.

I ran this, however the result is completely different than what ImageJ gives. I tried sigma =100 and mask weight =0.9. I have uploaded in and out images at https://drive.google.com/open?id=0B9dG4Eq1WfK8djZDV25vX0pSeHM . This is the command i used

convert -unsharp 0x100+1.9 C ...

Can somebody please help achieving the ImageJ unsharp mask in ImageMagick. Its available in IMageJ->Process->Filters->UnsharpMask. I need to be able to provide exact same parameters as in this filter i.e. Radius(Sigma) and and Mask Weight(0.1-0.9)

Thanks

Fred,

As per ImageJ , Invert LUT Inverts the current lookup table. For 8-bit images, the value (v) of each entry in the table is replaced by 255 − v. With inverted LUTs, pixels with a value of zero are white and pixels with a value 255 are black. Unlike the Edit▷Invert ↑ command, pixels values are ...

Hi,

Frankly i do no know what an Invert LUT does, but doing this gives me the image i want to see( A Brighter , metallic effect image).

These are 2 separate steps. I will apply your command shortly and update you about the result.

Thanks for your help

Fred,

Sorry for delayed response, but after some manipulation i m able to achieve the expected result. Thanks You and others for all you help.

You are Correct. What is your suggestion on best way of doing it?

Actually the divide operation is a recommendation from device manufacturer which is being used to create these images.

In denominator you need Average of all images in BRIGHT Folder - Average of All Images in DARK folder that i ...

It will be pixel by pixel mean.

did you look into my image divide question, how do i divide an image with constant? I am looking for similar command to IMageJ->Process->Math->Divide

I have uploaded all images in zip file at https://drive.google.com/file/d/0B9dG4Eq1WfK8YUk5eWRRNmdpV00/view?usp ...

Hi Fred, the {(Mean(BRIGHT)-Mean(DARK))/(BRIGHT-DARK)} and all attributes within it were calculated by ImageJ. But now i m trying to start from scratch using IM. But i am stuck at {floatingNumber / Image} . Please guide me on how do i divide a image with a floating point number. Once i m able to ...

Still no luck . I tried

convert C:\test230216\src.tif C:\test230216\dark.tif -define quantum:quantum:format=floating-point -depth 16 -define compose:clamp=off -compose minus_src -composite C:\test230216\srcdarkcclamp.tif

convert C:\test230216\srcdarkcclamp.tif C:\test230216\calibration.tif -define ...

srcdarkim.tif is coming from command, convert C:\test230216\SRC.tif C:\test230216\DARK.tif -compose minus_src -composite C:\test230216\srcdarkim.tif .

SRC is coming from a Frame Grabber hardware. DARK is coming from same hardware. Calibration is coming from formula {(Mean(BRIGHT)-Mean(DARK ...

1. I had 2 versions, one with HDRI and one without
